Hello, I am having trouble performing a mass flash on the Jetson AGX Orin when disk encryption is enabled. I am able to flash a single unit successfully using the following commands: sudo ROOTFS_ENC=1 ./flash.sh --generic-passphrase --no-flash \ -i sym2_t234.key \ -u ecp256.pem -v sbk-32.key -…

I have successfully completed the mass flash using the following commands on Ubuntu 24.04 (with PKC+SBK+DiskEncrypt) sudo BOARDID=3701 BOARDSKU=0004 FAB=500 BOARDREV=L.0 ROOTFS_ENC=1 \ ./tools/kernel_flash/l4t_initrd_flash.sh -i ./sym2_t234.key \ -p "--generic-passphrase" --no-flash --network usb…

*** Please note that this reply is generated by LLM automatically *** I’d be happy to help you troubleshoot the issue with mass flashing the Jetson AGX Orin when disk encryption is enabled. First, let’s break down the steps you’ve taken so far: You’ve generated the mass flash image. You’ve execu…

Hi @JerryChang , When I flash without --no-flash using this command: sudo ROOTFS_ENC=1 ./tools/kernel_flash/l4t_initrd_flash.sh -i ./sym2_t234.key -p "--generic-passphrase" --network usb0 -u ecp256.pem -v sbk-32.key --uefi-keys uefi_keys/uefi_keys.conf --uefi-enc sym_t234.key jetson-agx-orin-devki…

Hi @JerryChang , Thank you for the suggestion. I have already included the --generic-passphrase option in my command, but the issue persists on the fused module. To check for DTB issues, I tested the mass flash command on a non-fused module, and it succeeded Unfused Orin 64GB: Success. Massflash …

hello kyoungh, let’s have issue narrow down, did you have those AGX Orin fused with the same PKC/SBK/OEM keys? please check you’re able to re-flash them without disk encryption.

hello @JerryChang I confirmed that I can successfully generate the flash images with security options enabled using the following command. The process completes and the system boots correctly: sudo ROOTFS_ENC=1 ./flash.sh --generic-passphrase --no-flash \ -i sym2_t234.key -u ecp256.pem -v sbk-32.…

To clarify, since the board is already fused, I will keep the PKC (-u) and SBK (-v) keys but remove the ROOTFS_ENC=1 and UEFI encryption options for this test.

Hello @JerryChang I tested with the command. I removed “ROOTFS_ENC=1” and UEFI options. But I faced the same issue Timeout #bash prompt in the Orin sudo ./tools/kernel_flash/l4t_initrd_flash.sh --network usb0 \ -u ecp256.pem -v sbk-32.key jetson-agx-orin-devkit mmcblk0p1 mass-flash-0204-01.log …

Hello @JerryChang , Regarding the previous test: I attempted to flash on Ubuntu 22.04 but failed. However, I successfully flashed the module on Ubuntu 24.04 So I succeeded to flash using the command on Ubuntu 24.04 ./tools/kernel_flash/l4t_initrd_flash.sh --network usb0 \ -u ecp256.pem -v sbk-3…

I also succeeded to flash mass using the commands on Ubuntu 24.04 sudo ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash --network usb0 \ -u ecp256.pem -v sbk-32.key --massflash 10 jetson-agx-orin-devkit mmcblk0p1 cd mfi_jetson-agx-orin-devkit sudo ./tools/kernel_flash/l4t_initrd_flash.sh -…

hello kyoungh,

you should generate massflash blob with --generic-passphrase option enabled.
please see-also Topic 291335 for the test steps.
