Hi Team,
Using TMS570LC4357 for online upgrade function. The app runs by writing the app program to the app store through the bootloader and then the boot program runs to the app. However, the app program does not run after power-up through software, hardware, or power-down.

2) Flash writes to the liabrary:
3) Once the program is written, entering app:
4) The bootloader powers up and runs to app:
5) The bootloader also writes and saves some app parameters after flash (0x003E0000U).
And the test results are as follows:
a. Download bootloader, erase only the area used by bootloader and boot app program, the app is working properly.
b. After the bootloader writes the app program to memory, boot the app program directly, and the app works.
c. After the bootloader writes the app program to memory, it does not run the app, the software resets the CPU. Boot the app program, app does not function properly.
d. After the bootloader writes the app program to memory, it does not run the app, and the CPU is reset by hardware. Boot the app program and the app works.
e. After the bootloader writes the app program to memory, do not run the app, power it up again, boot the app program, app does not function properly.
Could you help check this case? Thanks.
Best Regards,
Cherry
