hello tanzelur,
it’ll be an issue with this 3rdparty board.
for instance, please check.. $OUT/Linux_for_Tegra/tools/ota_tools/version_upgrade/ota_board_specs.conf
re-cap as below..
# List the supported t23x devices
T23X_DEVICES=(
'JETSON_AGX_ORIN_DEVKIT'
'JETSON_AGX_ORIN_DEVKIT_INDUSTRIAL'
'JETSON_ORIN_NANO_DEVKIT'
as you can see.. there’s no board configuration, p3509-a02-p3767-0000
please see-also Topic 332980, which gives an example for customize board to create OTA payloads.
