Hello Teacher:
When I was debugging UART with my own designed Orin Nano devkit (JetPack 5.1.5), I found that UART 0 and UART 2 were not turned on in the device tree, so I modified the device tree(Previously, Teacher Kevin FFF helped me with debugging guidance, but he seems to be too busy lately). The modification result is as follows:
The original image is as follows:
The modified image is as follows:
But after the modification, the system cannot start up. Could you please guide me, teachers? Have I not finished the modification yet？
orin_nano_start.log (49.0 KB)
The following are the logs saved during my startup process, please refer to them.
It was correct to change the “status = "disabled"” to “status = "okay"”. Do verify that the device tree edit was actually used in the running device tree. This directory is an exact reflection of the running device tree, and you can navigate through it just like the device tree file until you get to the directory corresponding to “serial@3110000”, and then “cat status” to see if it says “okay”:
cd /proc/device-tree
# ...just navigate to your edit with cd and use cat to verify...
This the duplicate topic as Request to resolve UART debugging issues - #38 by KevinFFF, I have updated there.
Let’s just discuss same issue in one topic, thanks.
You reply to messages very slowly, and I am reposting, but you are not happy. What should I do to solve the problem?
Sorry that it’s the holiday season and I’m not here to update.
I’ve replied you in another topic.
