Dear all,

 

Our system has a problem of the unanticipated USB disconnection.

 

I found following Errata.

 

http://cache.nxp.com/files/32bit/doc/errata/IMX6SDLCE.pdf

- ERR004534 USB: Wrong HS disconnectio n may be generated after resume

- ERR004535 USB: USB suspend and resume flow clarifications

 

Our system is based on L3.0.35_4.1.0_130816_source.tar.gz(NXP BSP).

 

I understand that these Workarounds are included in this BSP.

 

However, I suspect that Errata issue occurs.

Therefore I want to confirm whether these Workarounds are included.

 

Would you tell me a file position and the concrete code that these Workarounds are included in?

 

Best Regards,

Yuuki
