There may be situations where you accidentally emptied the flash or if the flash is damaged on your board. In these situations, it's better to recover the bootloader. 36 | 37 | Before you recover the bootloader, please double check the boot mode jumpers(Switch_2) on your board has already been switched to UART mode(GPIO_1,GPIO_0: 1,1); 38 | 39 | 1. Configure the serial port settings: 115200bps; 40 | 41 | 2. Power up, you will see an output like this: 42 | 43 | ``` 44 | CCCCCCCCCCCCCCCCCCCCC 45 | ``` 46 | 47 | 3. Please transfer the recovery binary **`jh7110-recovery-20221205.bin`** by xmode and you will see recovery menu automaticlly; 48 | ``` 49 | JH7110 secondboot version: 221205-74596a9 50 | CPU freq: 1250MHz 51 | idcode: 0x1860C8 52 | ddr 0x00000000, 4M test 53 | ddr 0x00400000, 8M test 54 | DDR clk 2133M, size 8GB 55 | ********************************************************* 56 | ****************** JH7110 program tool ****************** 57 | ********************************************************* 58 | 0: update 2ndboot/SPL in flash 59 | 1: update 2ndboot/SPL in emmc 60 | 2: update fw_verif/uboot in flash 61 | 3: update fw_verif/uboot in emmc 62 | 4: update otp, caution!!!! 63 | 5: exit 64 | NOTE: current xmodem receive buff = 0x40000000, 'load 0x********' to change. 65 | select the function to test: 66 | ``` 67 | 4.

By contrast, the GNU General Public 38 | License is intended to guarantee your freedom to share and change free 39 | software--to make sure the software is free for all its users. This 40 | General Public License applies to most of the Free Software 41 | Foundation's software and to any other program whose authors commit to 42 | using it. (Some other Free Software Foundation software is covered by 43 | the GNU Library General Public License instead.) You can apply it to 44 | your programs, too. 45 | 46 | When we speak of free software, we are referring to freedom, not 47 | price. Our General Public Licenses are designed to make sure that you 48 | have the freedom to distribute copies of free software (and charge for 49 | this service if you wish), that you receive source code or can get it 50 | if you want it, that you can change the software or use pieces of it 51 | in new free programs; and that you know you can do these things. 52 | 53 | To protect your rights, we need to make restrictions that forbid 54 | anyone to deny you these rights or to ask you to surrender the rights. 55 | These restrictions translate to certain responsibilities for you if you 56 | distribute copies of the software, or if you modify it. 57 | 58 | For example, if you distribute copies of such a program, whether 59 | gratis or for a fee, you must give the recipients all the rights that 60 | you have. You must make sure that they, too, receive or can get the 61 | source code. And you must show them these terms so they know their 62 | rights. 63 | 64 | We protect your rights with two steps: (1) copyright the software, and 65 | (2) offer you this license which gives you legal permission to copy, 66 | distribute and/or modify the software. 67 | 68 | Also, for each author's protection and ours, we want to make certain 69 | that everyone understands that there is no warranty for this free 70 | software. If the software is modified by someone else and passed on, we 71 | want its recipients to know that what they have is not the original, so 72 | that any problems introduced by others will not reflect on the original 73 | authors' reputations. 74 | 75 | Finally, any free program is threatened constantly by software 76 | patents. We wish to avoid the danger that redistributors of a free 77 | program will individually obtain patent licenses, in effect making the 78 | program proprietary. To prevent this, we have made it clear that any 79 | patent must be licensed for everyone's free use or not licensed at all. 80 | 81 | The precise terms and conditions for copying, distribution and 82 | modification follow. 83 | 84 | GNU GENERAL PUBLIC LICENSE 85 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 86 | 87 | 0. This License applies to any program or other work which contains 88 | a notice placed by the copyright holder saying it may be distributed 89 | under the terms of this General Public License. The "Program", below, 90 | refers to any such program or work, and a "work based on the Program" 91 | means either the Program or any derivative work under copyright law: 92 | that is to say, a work containing the Program or a portion of it, 93 | either verbatim or with modifications and/or translated into another 94 | language. (Hereinafter, translation is included without limitation in 95 | the term "modification".) Each licensee is addressed as "you". 96 | 97 | Activities other than copying, distribution and modification are not 98 | covered by this License; they are outside its scope. The act of 99 | running the Program is not restricted, and the output from the Program 100 | is covered only if its contents constitute a work based on the 101 | Program (independent of having been made by running the Program). 102 | Whether that is true depends on what the Program does. 103 | 104 | 1. You may copy and distribute verbatim copies of the Program's 105 | source code as you receive it, in any medium, provided that you 106 | conspicuously and appropriately publish on each copy an appropriate 107 | copyright notice and disclaimer of warranty; keep intact all the 108 | notices that refer to this License and to the absence of any warranty; 109 | and give any other recipients of the Program a copy of this License 110 | along with the Program. 111 | 112 | You may charge a fee for the physical act of transferring a copy, and 113 | you may at your option offer warranty protection in exchange for a fee. 114 | 115 | 2. You may modify your copy or copies of the Program or any portion 116 | of it, thus forming a work based on the Program, and copy and 117 | distribute such modifications or work under the terms of Section 1 118 | above, provided that you also meet all of these conditions: 119 | 120 | a) You must cause the modified files to carry prominent notices 121 | stating that you changed the files and the date of any change. 122 | 123 | b) You must cause any work that you distribute or publish, that in 124 | whole or in part contains or is derived from the Program or any 125 | part thereof, to be licensed as a whole at no charge to all third 126 | parties under the terms of this License. 127 | 128 | c) If the modified program normally reads commands interactively 129 | when run, you must cause it, when started running for such 130 | interactive use in the most ordinary way, to print or display an 131 | announcement including an appropriate copyright notice and a 132 | notice that there is no warranty (or else, saying that you provide 133 | a warranty) and that users may redistribute the program under 134 | these conditions, and telling the user how to view a copy of this 135 | License. (Exception: if the Program itself is interactive but 136 | does not normally print such an announcement, your work based on 137 | the Program is not required to print an announcement.) 138 | 139 | These requirements apply to the modified work as a whole. If 140 | identifiable sections of that work are not derived from the Program, 141 | and can be reasonably considered independent and separate works in 142 | themselves, then this License, and its terms, do not apply to those 143 | sections when you distribute them as separate works. But when you 144 | distribute the same sections as part of a whole which is a work based 145 | on the Program, the distribution of the whole must be on the terms of 146 | this License, whose permissions for other licensees extend to the 147 | entire whole, and thus to each and every part regardless of who wrote it. 148 | 149 | Thus, it is not the intent of this section to claim rights or contest 150 | your rights to work written entirely by you; rather, the intent is to 151 | exercise the right to control the distribution of derivative or 152 | collective works based on the Program. 153 | 154 | In addition, mere aggregation of another work not based on the Program 155 | with the Program (or with a work based on the Program) on a volume of 156 | a storage or distribution medium does not bring the other work under 157 | the scope of this License. 158 | 159 | 3. You may copy and distribute the Program (or a work based on it, 160 | under Section 2) in object code or executable form under the terms of 161 | Sections 1 and 2 above provided that you also do one of the following: 162 | 163 | a) Accompany it with the complete corresponding machine-readable 164 | source code, which must be distributed under the terms of Sections 165 | 1 and 2 above on a medium customarily used for software interchange; or, 166 | 167 | b) Accompany it with a written offer, valid for at least three 168 | years, to give any third party, for a charge no more than your 169 | cost of physically performing source distribution, a complete 170 | machine-readable copy of the corresponding source code, to be 171 | distributed under the terms of Sections 1 and 2 above on a medium 172 | customarily used for software interchange; or, 173 | 174 | c) Accompany it with the information you received as to the offer 175 | to distribute corresponding source code. (This alternative is 176 | allowed only for noncommercial distribution and only if you 177 | received the program in object code or executable form with such 178 | an offer, in accord with Subsection b above.) 179 | 180 | The source code for a work means the preferred form of the work for 181 | making modifications to it. For an executable work, complete source 182 | code means all the source code for all modules it contains, plus any 183 | associated interface definition files, plus the scripts used to 184 | control compilation and installation of the executable. However, as a 185 | special exception, the source code distributed need not include 186 | anything that is normally distributed (in either source or binary 187 | form) with the major components (compiler, kernel, and so on) of the 188 | operating system on which the executable runs, unless that component 189 | itself accompanies the executable. 190 | 191 | If distribution of executable or object code is made by offering 192 | access to copy from a designated place, then offering equivalent 193 | access to copy the source code from the same place counts as 194 | distribution of the source code, even though third parties are not 195 | compelled to copy the source along with the object code. 196 | 197 | 4. You may not copy, modify, sublicense, or distribute the Program 198 | except as expressly provided under this License. Any attempt 199 | otherwise to copy, modify, sublicense or distribute the Program is 200 | void, and will automatically terminate your rights under this License. 201 | However, parties who have received copies, or rights, from you under 202 | this License will not have their licenses terminated so long as such 203 | parties remain in full compliance. 204 | 205 | 5. You are not required to accept this License, since you have not 206 | signed it. However, nothing else grants you permission to modify or 207 | distribute the Program or its derivative works. These actions are 208 | prohibited by law if you do not accept this License. Therefore, by 209 | modifying or distributing the Program (or any work based on the 210 | Program), you indicate your acceptance of this License to do so, and 211 | all its terms and conditions for copying, distributing or modifying 212 | the Program or works based on it. 213 | 214 | 6. Each time you redistribute the Program (or any work based on the 215 | Program), the recipient automatically receives a license from the 216 | original licensor to copy, distribute or modify the Program subject to 217 | these terms and conditions. You may not impose any further 218 | restrictions on the recipients' exercise of the rights granted herein. 219 | You are not responsible for enforcing compliance by third parties to 220 | this License. 221 | 222 | 7. If, as a consequence of a court judgment or allegation of patent 223 | infringement or for any other reason (not limited to patent issues), 224 | conditions are imposed on you (whether by court order, agreement or 225 | otherwise) that contradict the conditions of this License, they do not 226 | excuse you from the conditions of this License. If you cannot 227 | distribute so as to satisfy simultaneously your obligations under this 228 | License and any other pertinent obligations, then as a consequence you 229 | may not distribute the Program at all. For example, if a patent 230 | license would not permit royalty-free redistribution of the Program by 231 | all those who receive copies directly or indirectly through you, then 232 | the only way you could satisfy both it and this License would be to 233 | refrain entirely from distribution of the Program. 234 | 235 | If any portion of this section is held invalid or unenforceable under 236 | any particular circumstance, the balance of the section is intended to 237 | apply and the section as a whole is intended to apply in other 238 | circumstances. 239 | 240 | It is not the purpose of this section to induce you to infringe any 241 | patents or other property right claims or to contest validity of any 242 | such claims; this section has the sole purpose of protecting the 243 | integrity of the free software distribution system, which is 244 | implemented by public license practices. Many people have made 245 | generous contributions to the wide range of software distributed 246 | through that system in reliance on consistent application of that 247 | system; it is up to the author/donor to decide if he or she is willing 248 | to distribute software through any other system and a licensee cannot 249 | impose that choice. 250 | 251 | This section is intended to make thoroughly clear what is believed to 252 | be a consequence of the rest of this License. 253 | 254 | 8. If the distribution and/or use of the Program is restricted in 255 | certain countries either by patents or by copyrighted interfaces, the 256 | original copyright holder who places the Program under this License 257 | may add an explicit geographical distribution limitation excluding 258 | those countries, so that distribution is permitted only in or among 259 | countries not thus excluded. In such case, this License incorporates 260 | the limitation as if written in the body of this License. 261 | 262 | 9. The Free Software Foundation may publish revised and/or new versions 263 | of the General Public License from time to time. Such new versions will 264 | be similar in spirit to the present version, but may differ in detail to 265 | address new problems or concerns. 266 | 267 | Each version is given a distinguishing version number. If the Program 268 | specifies a version number of this License which applies to it and "any 269 | later version", you have the option of following the terms and conditions 270 | either of that version or of any later version published by the Free 271 | Software Foundation. If the Program does not specify a version number of 272 | this License, you may choose any version ever published by the Free Software 273 | Foundation. 274 | 275 | 10. If you wish to incorporate parts of the Program into other free 276 | programs whose distribution conditions are different, write to the author 277 | to ask for permission. For software which is copyrighted by the Free 278 | Software Foundation, write to the Free Software Foundation; we sometimes 279 | make exceptions for this. Our decision will be guided by the two goals 280 | of preserving the free status of all derivatives of our free software and 281 | of promoting the sharing and reuse of software generally. 282 | 283 | NO WARRANTY 284 | 285 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 286 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 287 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 288 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 289 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 290 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 291 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 292 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 293 | REPAIR OR CORRECTION. 294 | 295 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 296 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 297 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 298 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 299 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 300 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 301 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 302 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 303 | POSSIBILITY OF SUCH DAMAGES. 304 | 305 | END OF TERMS AND CONDITIONS 306 | 307 | How to Apply These Terms to Your New Programs 308 | 309 | If you develop a new program, and you want it to be of the greatest 310 | possible use to the public, the best way to achieve this is to make it 311 | free software which everyone can redistribute and change under these terms. 312 | 313 | To do so, attach the following notices to the program. It is safest 314 | to attach them to the start of each source file to most effectively 315 | convey the exclusion of warranty; and each file should have at least 316 | the "copyright" line and a pointer to where the full notice is found. 317 | 318 | 319 | Copyright (C) 320 | 321 | This program is free software; you can redistribute it and/or modify 322 | it under the terms of the GNU General Public License as published by 323 | the Free Software Foundation; either version 2 of the License, or 324 | (at your option) any later version. 325 | 326 | This program is distributed in the hope that it will be useful, 327 | but WITHOUT ANY WARRANTY; without even the implied warranty of 328 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 329 | GNU General Public License for more details. 330 | 331 | You should have received a copy of the GNU General Public License 332 | along with this program; if not, write to the Free Software 333 | Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 334 | 335 | 336 | Also add information on how to contact you by electronic and paper mail. 337 | 338 | If the program is interactive, make it output a short notice like this 339 | when it starts in an interactive mode: 340 | 341 | Gnomovision version 69, Copyright (C) year name of author 342 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 343 | This is free software, and you are welcome to redistribute it 344 | under certain conditions; type `show c' for details. 345 | 346 | The hypothetical commands `show w' and `show c' should show the appropriate 347 | parts of the General Public License. Of course, the commands you use may 348 | be called something other than `show w' and `show c'; they could even be 349 | mouse-clicks or menu items--whatever suits your program. 350 | 351 | You should also get your employer (if you work as a programmer) or your 352 | school, if any, to sign a "copyright disclaimer" for the program, if 353 | necessary.
