Hi,

I’m using BSP 35.2 for Jetson Xavier and I’m running flash.sh to sign the images, but the signig fails with the following log:

Welcome to Tegra Flash

Command tegrahost_v2 --chip 0x19 0 --magicid MB1B --appendsigheader mb1_t194_prod.bin zerosbk

I have a few questions about that tegrahost_v2 tools:

  • What does it do?
  • What could cause the return value -11?

hello aleksei.fedotov,

may I also have your complete command-line for reference?
besides, did you fused your device or not?

I’m running the following command

FAB=100 BOARDID=3668 BOARDSKU=0001 BOARDREV= CHIPREV=2 FUSELEVEL="fuselevel_production" ROOTFS_AB=1 NO_ROOTFS=1 NO_RECOVERY_IMG=1 ./flash.sh --no-flash --no-systemimg --no-root-check --bup --multi-spec jetson-xavier-nx-devkit-emmc mmcblk0p1

The device I want to flash is fused but not connected.

hello aleksei.fedotov,

since the target is fused, you’ll need to provide all those keys.
besides, these commands looks contradiction. are you trying to speed-up the process to create sign/encrypt binary files?

since the target is fused, you’ll need to provide all those keys.

I already run flash.sh to sign the binaries and I’m running this command just to generate capsule update (BUP) for the device.

hello aleksei.fedotov,

there’s a script file, l4t_generate_soc_capsule.sh.
please see-also developer guide, Generating the Capsule Update Payload.

besides,
you may see-also external wiki page for the steps to run capsule update.
