Hello guys, I try to flash my r36.4 to Jetson Orin NANO board, but the debug serial gives me this error Bad parameter: eks image not correct. The board works for r35.5.0, but when I try to flash with r36.4 it fails.
Environments
- Customized board (we do not have devkit)
- SDK version: r36.4
- Default eks img
What I’ve tried:
- regenerate eks.img with
example.sh - add debug info in
jetson_user_key_pta.c.
Regenerating eks.img has no help to this problem
I try to print ekb_content with the following code in ekb_extraction_process

It seems that the ekb_addr has missed 16 bytes offset, the magick number is at 0x24 but the code gives me 0x14.
