Jetson TX2i - Disable ECC using Jetpack 4.6.5

[zekun.zhang]

Hello ! I try to disable the ECC on a new Jetson TX2i module (PCN210521). However the flash process always hangs at 99% with error CPU Bootloader is not running on device or Cannot open USB.

My Jetpack version is 4.6.5 because of the firmware changes in this TX2i module.

I followed the doc in previous version of Jetpack (3.2), because I couldn’t find instructions on ECC deactivation in newer documentations of Jetpack. The doc is shown in the following image

I also used docker image sdkmanager:2.1.0.11682-Ubuntu_18.04 to flash TX2i, my command is docker-entrypoint.sh --cli --action install --login-type devzone --product Jetson --target-os Linux --version 4.6.5 --host --target JETSON_TX2_TARGETS --flash --license accept --stay-logged-in true --collect-usage-data disable

I also tried to modify jetson-tx2-devkit-tx2i.conf (because the TX2i module is installed on the TX2 devkit) with the same modifications as jetson-tx2i.conf, but it doesn’t work either.

Is it still possible to disable ECC on TX2i with Jetpack 4.6.5 ?

Hi zekun.zhang,

Have you referred to Removing the DRAM ECC Partition which is from developer guide of R32.7.5?

Please also share the full flash log for further check.

I also used docker image sdkmanager:2.1.0.11682-Ubuntu_18.04 to flash TX2i

Please get a standalone Ubuntu as you host PC instead of using docker/VM to flash the board.
