Hello,
I am working on the USB Peripheral driver for the OMAP3530 to be used by the CDC funcion class. I am able to enumerate the device, this is my setup:
EP1 -Interrupt
EP2- Bulk IN
EP3- Bulk OUT
When I am connected in Full Speed mode this is what happens:
* When I send data (via a Hyperterminal or PuTTY, just one character at a time) I am able to send few bytes, sometimes only 1, others only 4, sometimes 15 or a little more and then EP3 starts NAK'ing.
On High Speed:
* When I send data I get a NYET, then a PING (which is ACK'd) and then the host tries again but it receives a NYET packet.
I noticed that since the first packet (which is only one byte) I read 0x03 on the RXCSR for the EP which means RXPKTRDY and FIFOFULL, but I have only sent one byte. I am configuring the FIFOs (I have checked the registers after configuring the Endpoints) correctly (in FS, 64 bytes per endpoint).
Anyone has any idea as to what could be wrong?
