Linux Kernel

[inigo_irisbond]

Dear NXP Support Team,

We are working on Linux Debian based embedded device with a kernel version 4.19.35.  We are working with an iMX8Mmini, and we are configuring it as USB port device; our device is connected to tablets (as Host) via USB communicationOur application works well when the device we are connecting to is awake, however, we have an error after that device goes to suspend-wake up.In these cases, we can observe, from the Linux side, that EP1 and EP2 endpoints (write and read endpoints) are blocked. At Kernel level, we can see the following error coming from the configs-gadget module:

# [   26.043343] configfs-gadget gadget: End Point Request ERROR: -108
# [   26.118312] configfs-gadget gadget: high-speed config #1: c

Could you please advise on how to resolve this issue?

Hello @inigo_irisbond 

Unfortunately, we do not support Debian in our boards. Could you please give to me some steps to try to replicate the issue (if possible). Also, you can try with our BSP that you can download in our web page:

I hope this can helps to you.

Best regards.
