AM3352: Am3352 USB crash

Hi Anees,

Anees Shahul1 said:

I have an issue with USB port , when I disconnect the cable from usb port from AM335x , I get kernel panic, or if I remove the cable and do ifconfig some times, it will crash. the kernel panic is below

Please describe the USB topology in your setup.

The DTS shows USB0 port is configured in peripheral-only mode and USB1 is in host-only mode? which port the cable is attached to? Is another USB port in use while disconnecting the cable?

When you do ifconfig, it is to the CPSW Ethernet port or a USB Ethernet port?

Please run the following script on your board after booted into linux and before trigger the issue, and provide its output.

Hi Anees,

What is the OS running on the USB host?

I am not sure what causes the issue. Just for testing, please do the following change in your kernel:

1. change usb0 dr_mode from "peripheral" to "otg" in DTS;

2. configure kernel to build g_ether driver as module, not build it in kernel. And do 'modprobe g_ether" on your board linux prompt to load this driver after booted;

3. do the test to see if the issue still happen.

Hi

I followed a TI document where USB configuration is mentioned

Looking forward to your test result.

Yes, i will get to it . thanks!!!
