TCIEVMK2X: xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command

Ben Aranguren
Prodigy 60 points

Part Number: TCIEVMK2X

The EVM board I'm using is labeled rev 40 running TI processor SDK ver 03.03.00.04.

root@k2hk-evm:~# uname -r
4.4.41-rt50-g968d071ce9

I run a USB transfer test which includes reading from a USB 2.0 flash drive and writing to /dev/null in a loop

dd of=/tmp/400M if=/dev/sda1 bs=100M count=4

After a few iterations, dd command would fail with the following message in dmesg:

[  158.182218] xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command.

The following UCD updates have been done:

  1. UCD9090_104_A04_TI_30%_20151120.txt
  2. UCD9244_52_A05.txt

Any suggestions?

    Hi, Ben,

    Let me try with the latest SDK and see if I can reproduce the issue. Your kernel version is very old and beyond support. The latest kernel version is 4.19. I'll get back to you once I have a result.

    Hi, Ben,

    I don't see the issue with 4.19.59 kernel (PLSDK 6.1 release). Below is the console log. I increased the loop to 100 and still not seeing the issue. Do you want to try the latest SDK?

    for (( i=0; i<10; i++ ))
    do
    echo -n "$i "
    dd of=/tmp/400M if=/dev/sda bs=100M count=4
    printf "\r\n"
    done
