Attempting to flash a TX2 NX SoM throws UnicodeDecodeError #23

Closed atoaster closed 1 year ago

atoaster commented 3 years ago

Hi All, it's me again

I've been toying with using a TX2 NX SoM on your amazing baseboard, but I am getting a UnicodeDecodeError when trying to flash it with the L4T tools.

Here is the full output from nvautoflash in JetPack 4.6 (note that this folder was made by the sdkmanager):

*** Checking target board connection ... 1 connections found.

I've gone down the Nvidia Forum rabbit hole and it led me here, indicating I need some kinda board configuration file "from the vendor".

Does this file exist anywhere? Or do I need to make it? Has anyone succeeded in flashing JetPack 4.6 on a TX2 NX SoM with this baseboard?

I've not tested 4.6, but the CLI workflow does work for 4.5.1 (e.g L4T 32.5.1).

wget https://developer.nvidia.com/embedded/l4t/r32_release_v5.1/r32_release_v5.1/t186/tegra186_linux_r32.5.1_aarch64.tbz2
wget https://developer.nvidia.com/embedded/l4t/r32_release_v5.1/r32_release_v5.1/t186/tegra_linux_sample-root-filesystem_r32.5.1_aarch64.tbz2

export L4T_RELEASE_PACKAGE='tegra186_linux_r32.5.1_aarch64.tbz2'
export SAMPLE_FS_PACKAGE='tegra_linux_sample-root-filesystem_r32.5.1_aarch64.tbz2'

tar xvf ${L4T_RELEASE_PACKAGE}
cd Linux_for_Tegra/rootfs/
sudo tar xvpf ../../${SAMPLE_FS_PACKAGE}
cd ..

sudo ./apply_binaries.sh
sudo ./flash.sh jetson-xavier-nx-devkit-tx2-nx internal

I can try the above with the proper links for 4.6, but likely not in the next day or two. If you want to attempt, the L4T archive has the URLs:

Welp, just tried 4.5.1 using the sdkmanager and it worked fine, whereas 4.6 did not.

I guess it's just something to do with 4.6 specifically?

Will leave this issue open if you find anything but otherwise my problem is solved by just using 4.5.1 :)
