TX2 (p3310) UART configuration

hello Henry.Lou,

please enter /etc/systemd/, you may modify nvgetty.sh for adding configurations.

Hi @JerryChang
We added configuration in the nvgetty.sh on the host pc, and used “flash -r -k kernel jetson-tx2 mmcblk0p1”. But, when device brought up, the script did not chang. Could you give the right command to flash?

hello Henry.Lou,

you don’t need to re-flash kernel partition, just edit the script and save the modifications.

Hi @JerryChang
There are thousends of products, we can not edit the nvgetty.sh one by one.
So, please offer us the flash command.

hello Henry.Lou,

can you please test on single device to confirm adding the configurations in nvgetty.sh resolve your issue.

once you confirm the solution, you may modify the file on your local host.
that’s rootfs for flashing to targets. for example, ~/nvidia/nvidia_sdk/JetPack_<version>_Linux_<platform>/Linux_for_Tegra/rootfs/etc/systemd/nvgetty.sh

if you would like to install binaries, or having a different rootfs, please refer to Setting Up the Root File System.

for flashing devices.
you should execute the flash.sh without -r options, for creating a new system.img to include that changes.
