usb3.0 fail on i.mx8mq

wenfu · ‎10-13-2020

Hello,

Hardware:customer board with i.mx8mq SOC

Software: linux 5.4.24 nxp release

We use USB3.0 host port to connect with a USB3.0 device. USB disconnect randomly during the communication preocess. Sometime it happens after several minutes and sometimes several hours.

But our application is very strict on stability.

Here are some kernal log when fail happens:

Hi wenfu

one can try patch provided on link

https://community.nxp.com/t5/i-MX-Processors/i-MX8M-USB3-0-HC-died-with-external-USB3-0-hub/m-p/9685...

Best regards
igor

wenfu · ‎10-14-2020

thank you igorpadykov,

we have seen this issue in the communitytryed this patch before and we have tryed it. but the issue still exist.

I think this patch can solve issue with USB HUB, but my sinario has no HUB, the USB device was connected to i.mx8 directly.

igorpadykov · ‎10-14-2020

Hi wenfu

also issue may be related to usb layout (high signal loss, noise), suggest to recheck it using

i.MX8M Hardware Developer’s Guide

Best regards
igor

wenfu · ‎10-17-2020

I don't think this is a hardware issue because we can use USB3.0 Disk normally.

igorpadykov · ‎10-17-2020

one can try to reproduce issue on NXP i.MX8MK EVK reference board,

if it can not be reproduced, then seems this issue is related to custom board.

Best regards
igor

Hi igorpadykov,

i.MX8MK EVK reference board is OK. We have tested it.

We have found some clue for the failue of USB3.0. When we run iperf to test the ethernet throughput capacity, no matter there are USB transfer or not, and no matter what the devices is,U-disk or other usb3.0 devices, it will fiall. like the bellow kernel msg shows. So it seems ethernet cause USB3.0 fial. I konw EVK board is OK, and we have belief on i.mx8 platform, that's way we choose nxp. I just want you team to give some advices or guidance. The main difference between nxp EVK and our board is we use 2GB ddr4 and rohm pmic and EVK use 3GB lpddr4 and nxp pmic. Looking forward to you reply.
