Are there clear indicators that ERR050101 is occuring?

Hi there,

I am running into an issue on the RT1051. The device has isochronous USB IN and OUT endpoints. When connected to certain hosts (both directly and through a hub) the USB audio device enumerates properly and the host sends isochronous data to the device, however the OTG1_IRQHandler is not invoked by the isochronous packets. I am wondering if the issue I am seeing is related to the 'ERR050101 USB: Endpoint conflict issue in device mode' defect as described in Chip Errata for the i.MX RT1050, Rev. 2.2 (see attached).

Are there any clear indicators that I can observe using my IDE and debugger to determine if ERR050101 is occurring?

Thanks,

Michael

Hello Michael,

Unfortunately, there is no flag or specific register that could tell us that the errata is occurring. However, if you are in the same scenario as described in ERR050101 when ISO IN endpoint is used and the corresponding interrupt is not occurring then we can infer you are facing same issue.

Best regards,

Felipe
