zigbee OTA提示OTA invalid image

fff

ota 到最后结束时，设备提示 ota invalid image. 什么意思？ 怎么处理？

TL_YB

应该是格式或校验失败了，可以在ota_imageDataProcess()中定位一下。

fff

你好，不知道如何处理这个？

TL_YB

在ota_imageDataProcess()函数中加一些调试变量，看是哪里返回的invalid image。

fff

是这里CRC异常，怎么解决？

Maybe you can have a look in my post with this issue - https://forum.telink-semi.cn/forum.php?mod=viewthread&tid=417&extra=page%3D6
I don't know if it is the same issue.

谢谢，没有理解你怎么解决的。怎么操作的。

The problem I had was that the file tl_check_fw2.exe in tools directory was missing - it was deleted by antivirus. The CRC is added to the end of the firmware file. This files generates CRC after compilation.

At the end of compilation I had the following message:

    "../../../tools/tl_check_fw.sh" ht7017 tc32
    *****************************************************
    this is post build!! current configure is :ht7017
    copy from `ht7017.elf' [elf32-littletc32] to `ht7017.bin' [binary]
    ../../../tools/tl_check_fw.sh: line 6: ../../../tools/tl_check_fw2.exe: No such file or directory
    **************** end of post build ******************


If you have the same message (after you clean the project and recompile it) check the tools directory if you have file tl_check_fw2.exe.

You can also open your firmware file with any hex editor and have a look at offset 6-7. You should have 5D 00 if there is CRC in the firmware file

That's what is checked in this function first - it is reading flash_read(baseAddr + 6, 2, (u8 *)&crcFirmware);

flash_read(baseAddr + 6, 2, (u8 *)&crcFirmware);    if(((crcFirmware & 0xff) == 0x5D) && ((crcFirmware >> 8) & 0xff) == 0x02){

You may have a different reason. That was my problem.

我们可能是同一个问题，你怎么解决这个问题？

我参考了文件夹，没有这个tl_check_fw2.exe 文件
