Dear Champs,
Customer used our usb_dev_serial example code to test USB FIFO.
The client is MCU and the host is CPU. Wehn host CPU sent 1.8KB data(1000 frames, every frame including 2 head bytes and 16 data bytes) to MCU.
But met some frames are lost in the usb driver function, USBEndpointDataGet (USB buffer is 1.8KB). They count the 16bytes data and only about 938 can be read.
Do you have any suggestions for this testing?
Thanks a lot.
