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
