I have some problems while trying to use the ota tool.

What could be the problem here that the file cannot be found?

Hi,

Please provide the complete commands for performing an OTA update.
What are your BASE_BSP and TARGET_BSP?
Have you followed the official guidance?

Thanks

I would like to reflash a board flashed with the same version.

I have used the following environment variables:

export BASE_BSP=/home/nvidia/nvidia/nvidia_sdk/JetPack_5.1.2_Linux_JETSON_ORIN_NX_TARGETS_BASE_BSP/Linux_for_Tegra
export TARGET_BSP=/home/nvidia/nvidia/nvidia_sdk/JetPack_5.1.2_Linux_JETSON_ORIN_NX_TARGETS/Linux_for_Tegra

sudo ROOTFS_AB=1 ./tools/ota_tools/version_upgrade/l4t_generate_ota_package.sh brla4n-orin-nx R35-4

For the custom board i adapted the ota_board_specs.conf and extended it:

brla4n_orin_nx_ota_emmc_r35_spec=( 
'boardid=3767;fab=000;boardsku=0000;boardrev=;fuselevel_s=1;chiprev=;chipsku=00:00:00:D3;board=brla4n-orin-nx;rootdev=nvme0n1p1;bup_type=bl;signed_img_dir=images-R35-ToT'
)

BRLA4N_ORIN_NX_R35_4_ALIAS="brla4n_orin_nx_ota_emmc_r35_spec"

T23X_DEVICES=(
	'IGX_ORIN_DEVKIT'
	'JETSON_AGX_ORIN_DEVKIT'
	'JETSON_AGX_ORIN_DEVKIT_INDUSTRIAL'
	'JETSON_ORIN_NANO_DEVKIT'
	'BRLA4N_ORIN_NX'
)

I found the problem. The custom device was not supportet in the l4t_generate_ota_package.sh

SUPPORTED_EXTERNAL_DEVICES=(
	'jetson-xavier-nx-devkit-emmc:nvme0n1'
	'jetson-orin-nano-devkit:nvme0n1'
	'brla4n-orin-nx:nvme0n1'
)

It might be good to allow any custom device.
