BootROM bug? Seek solution to recover SOM fused with SBKPKC but not OemKeyValid bit

Hi Jerry,

Thanks for your support.

It seems like we are not in sync with what the problem is.

The problem is: I cannot fuse it anymore. The mb1 sent to SOM is rejected. The host side (Linux PC) gets error “"ERROR: might be timeout in USB write.”

Here are the detailed log files:

log-on-host-side.txt (19.3 KB)

log-on-target-side.txt (36.9 KB)

current-fuse-content.txt (1.0 KB)

The fuse command & conf are exactly yours

sudo ./odmfuse.sh -X ${FUSE_CONF_XML} -i 0x23 -k ${RSA_KEY} -S ${SBK_KEY} jetson-orin-nano-devkit-super

These two threads seem to have the same problem. but they were closed without the solution in them.
