In the DRIVE OS 5.2.0 update matrix, changing to DRIVE Software 10 says to contact NVIDIA for details. What are the steps to downgrade from DRIVE OS 5.2.0 to DRIVE Software 10?

Hi @Michael_L ,

I’m check this with internal team and will get back to you. Thanks.

Downgrade from DRIVE OS 5.2.0 to DRIVE Software 10 is all done by sdkmanager except Aurix firmware.

After installing with sdkmanager, if you notice any problems with DRIVE Software 10, please refer to Flashing AURIX to flash DRIVE-V5.1.6-E3550-EB-Aurix-With3LSS-ForHyperion-StepA-3.05.04 with memtool on windows host (because Flashing AURIX on Xavier doesn’t work).

Important: In any case, do NOT click erase button to erase the UCB area. Once UCB is erased, the chip is dead.

Thanks for confirming it should work Vick. I’ll report back how it goes.

To prevent from accidentally bricking the system in using Memtool to flash aurix firmware, below is the prefered steps for downgrading everything to DRIVE Software 10 (also aurix firmware). Thanks.

  1. scp ~/nvidia/nvidia_sdk/DRIVE_Software_10.0_Linux_OS_DDPX/DRIVEOS/drive-t186ref-linux/targetfs_a/lib/firmware/DRIVE-V5.1.6-E3550-EB-Aurix-With3LSS-ForHyperion-StepA-3.05.04.hex to /lib/firmware/ of target system
  2. $ sudo /bin/bash /etc/systemd/scripts/nv_aurix_check_fw.sh -force_update DRIVE-V5.1.6-E3550-EB-Aurix-With3LSS-ForHyperion-StepA-3.05.04.hex
  3. install DRIVE Software 10 with sdkmanager.
