Tool/software:
Hello Team,
I am working with the AM62x-SK Board and encountering a "Bad Data CRC" error when attempting to boot from flash after using USB DFU to load kernel images.
Error with USB DFU Boot Process:
- I switch to USB DFU mode to load the same images.
- After transferring the images via USB DFU and writing them to flash, I attempt to boot using sf read.
This results in the following error:
Verifying Checksum ... Bad Data CRC
ERROR: can't get kernel image!
Successful Boot Process (Using UART Boot Mode):
- I boot the processor using UART mode.
- I load images into DDR via UART and then copy them to flash using sf write.
- Booting from flash afterward using sf read works perfectly without errors.
Troubleshooting Steps Taken:
- Verified that images are not corrupted when loaded via UART.
- Ensured flash offsets and sizes are correctly set during both UART and USB DFU processes.
- Compared memory contents in DDR after sf read from flash for both methods and observed data differences.
Could you advise on any specific configurations, limitations, or steps related to USB DFU on AM62x that could resolve this issue?
