Issue Description
<Please provide details about your query/application pipeline/usecase/pictures here >

Hello,

I want to know how to be able to change the os_args or kernel cmdline from the userspace.

This one is the default:

pl:[I]: Kernel Cmdline: aurixfw=AFW root=/dev/vblkdev0p1 loglevel=3 ip=off usr_fs=/dev/vblkdev1:/mnt/persistent/metadata usr_fs2=/dev/vblkdev2:/mnt/persistent/data rw_overlay=/dev/vblkdev3:/rw_overlay gpt rootwait rw gpt tegra_k

is there a tool in the userspace to change it?

Regards

Does Passing Additional Kernel Parameters | NVIDIA Docs? help?

Hi,

Thanks for the response.

I tried it, but it seems it is not supported for hypervisor:

Check finished successfully
There is no supported for specifying kernel-dtb with Hypervisor

command line used was:
['/drive/drive-foundation/tools/flashtools/bootburn/./bootburn.py', '-b', 'p3710-10-s05', '-B', 'qspi', '-x', '/dev/ttyACM5', '-d', 'kernel-dtb', '/drive/drive-foundation/virtualization/hypervisor/t23x/configs/t234ref-release/pct/p3710-10-s05/linux/tegra234-p3710-0010-a01-linux-driveav-gos.dtb', '-D']

Failed to initialize target config

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/drive/drive-foundation/tools/flashtools/bootburn/../bootburn_t23x_py/bootburn.py", line 255, in bootburn

Is there another way?
