Hello All,
Currently We are having issues with the USB controller inside the device tree table for the AGX 32 GB Development Module not working.
We are using a custom carrier board with the USB configuration in the attached diagram.
Changes from the NVIDIA carrier card dev kit include:
• Pins F12 and F13 of the AGX module remain unchanged from the NVIDIA carrier card dev kit circuit configuration, and the USB Type C port is working correctly.
• Pins C10 and C11 of the AGX module have been modified to connect to a single USB 2.0 Type A connector port.
• Pins A10 and A11 of the AGX module, originally connected to M.2 KEY E, have been changed to connect to a single USB 2.0 Type A connector port.
• Pins G10 and G11 of the AGX module are now unused.
environment:
Jetpack6(rev.2)
JetsonLinux R36.3
sdkmanager 2.1.0.11698
This is the serial log I see when I connect to the debug serial port during a boot:
DebugUARTPort.txt (70.9 KB)
This is the dmesg:
dmesg240823.txt (53.6 KB)
This is the device tree file I have been modifying
・The edited part is padctl@3520000 node
・Surround the original part with /**/ to mark the modified parts
kernel_tegra234-p3737-0000+p3701-0004-nv.dts (320.2 KB)
The USB Type A ports are not functioning properly.
We are seeking advice on two things:
・The correct modifications for the parts that are incorrectly edited in the file
・Other areas in the nodes that should be edited.
Any insights or suggestions would be greatly appreciated.
