I am developing a custom USB device on a iMX6q platform (Wandboard) Chipidea HDRC (highspeed dual role controller). The HID interface consists of a single Interrupt IN ep and ep0. It is required to send HID reports from Host to Gadget over ep0 (with set_report cmd on hidraw interface) in OUT direction. The size of each HID report is 64 bytes. The Chipidea HDRC is unable to receive/ process the 64 bytes of data over ep0 (OUT). The setup stage is fine. No UDC interrupt is raised by controller to indicate completion of transaction. The same data transfer works fine for <64 bytes (63, 63 etc) and >64 bytes (65, 66 etc) where the transfers are split as 64+n. Analyzer logs attached. 1. Is there an issue with Chipidea HDRC receiving wMaxPacketSize (i.e. 64 byte) aligned data transfers on ep0 in OUT direction? 2. Anything that needs to be configured/ added in descriptor or source to have completion interrupt hit on 64 bytes data transfer on ep0 OUT? THank you!!
