Hi Expert!,
We are using our custom HW (AM625).
We trying to boot the device from usb-dfu tool.
Faced some issue for our custom HW. We created a binary from YOCTO and tested on our custom HW and SK-EVM AM62x HW also.
In whole day we are able to flash binary on custom HW only once. After that if we tried to flash another time it shown like below.
FYI... we tried to uninstall the dfu-utill app and upgradation also but same issue we observed on our custom HW.

Any HW changes we need to do for that? because same binary tested on AM62x SK EVM it was working fine and dfu-util tool working fine as well.
In above statement once we flash tiboot3.bin it should show "tispl" name instead of bootloader.
When we did dfu-util -l then only.
Please check once.
Thanks,
Suraj.
