Hello
I’m attempting to debug a USB channel using a K22. The driver I’m using is a modified version of the Virtual Comm port example contained in the MQX 4.1.1 release. Namely it has been modified to provide 3 virtual comm ports.
The issue I’m seeing seems to be linked to not receiving a token done interrupt when I expect to and after that I can’t get any more data through that comm port. It feels like a state transition issue or an interrupt configuration issue to me but I can’t put my finger on it.
Any thoughts would be greatly appreciated.
Thanks,
