jetson-io.py issue #67

Closed SentryCoderDev closed 6 months ago

SentryCoderDev commented 6 months ago

Hello, I installed your OS, but unfortunately I still have the same problem. When I run the 40 pin expansion header (jetson-io.py), it turns on and off for half a second.

Do you have a solution suggestion?

Qengineering commented 6 months ago

I'm sorry. I'm not familiar with jetson-io.py. Given the number of posts on the NVIDIA forum, it looks there are a lot of similar issues. And all pretty low-level. Also with there solutions. One thing for sure, it is not your hardware.

SentryCoderDev commented 6 months ago

Hello, after reinstalling it was fixed. Your OS will be very useful to me, thank you again.

I also am getting this issue, with the error stating that no APP partition was found (when it runs lsblk -n -r -o partlabel). Here are the app partitions I do have:

TBC RP1 EBT WB0 BPF BPF-DTB FX TOS DTB LNX EKS BMP RP4

Will post update if I see a fix.

The issue is that the root file system needs the "APP" label, I'm guessing the image doesn't have this by default. I just verified the partition and added the label and now the utility loads.

sudo blkid (make sure you find the disk and partition number, probably the below mmc and partition 1) sudo parted /dev/mmcblk0 name 1 APP quit

Edit: this let me access the jetson-io and enable SPI, but it still doesn't work (the loopback test fails).
