Hi, I’m trying to test and validate the process outlined at - Tegra Linux Driver I’ve generated pkc, sbk and kek2 keys. pkc = openssl key generated as mentioned in guide sbk = 4x 8bit hex values, e.g. 0xaaaaaaaa 0xbbbbbbbb 0xcccccccc 0xdddddddd kek2 = 128 bit hex value I first attempted with -…

@DaneLLL Some good news, I was able to flash successfully (on the new devkit) and boot successfully. serial.log (37.6 KB) flash-secure.log (433.9 KB) I’ll reply to the email thread about the bricked jetson, thanks for your help.

I’m guessing I need to use the -p option?, but that would mean I can no longer make or test changes?

Hi, There is a patch for odmfuse.sh: [image] Secure Boot odmfuse programming step fail on 32.2.1 Jetson TX2 Matt Madison was able to solve this issue with a patch to odmfuse.sh . Based on his comments this fix might be TX2 specific. Please apply it and try again.
