imx6 ehci XactErr

[angelo_d]

Hi all,

was trying to get more info about this error.

imx6q manual says "not receive a valid response from the device (Timeout, CRC, Bad PID, etc.)."

What would be "etc", and how to determine the exact error in the above list ?

I am getting this error on storage media communication at 12Mbit in u-boot, after several retries, an error is returned. While Linux then can mount the media properly.

Thanks

angelo

Hello, were you able to fix that issue ?

We have the same problem here on an imx6 custom board,

with some USB drives reading files from u-boot fails with an XAct error, while it is working fine in the kernel.

Thanks,

Nicolas

Hi Angelo

"etc" means any data which are not listed as valid in usb specification.

>how to determine the exact error in the above list

usb errors can be debugged using description of usb driver

in Linux Manual included in Linux 4.19.35_1.1.0 Documentation

and usb specification found on usb.org Document Library | USB-IF 

Best regards
igor
