Hi Felipe, I am having an issue with dwc3 on TI AM57x device, and would like to ask for your comments. I use configfs to create a multi-function gadget on dwc3, mass_storage is the last function, it seems if I create 3 functions, the mass_storage enumeration will fail on the host. It works fine if only create 2 functions. The dwc3 tracepoints log shows after all the ep0 transfers for mass_storage, the very first epXin transfer is not complete - dwc3 programmed the urb, but never generates RX completion event. This also matches the bus analyzer trace - dwc3 NAKs the very first IN token for ever. I use the attached script to create the gadget, The macro FUNCS in the beginning of the script defines the functions to be created. Any comments are appreciated. -Bin.
