Other Parts Discussed in Thread: OMAPL138
Hi,
I am new to usb programming. I read the reference spruh77a and assume that the OMAP L138 usb programming procedure is:
1. PHY setup
1.1 clock setup
1.2 Mode setup
2. Endpoint setup
I don't know if this procedure is all for OMAP side usb programming. I assume that OMAP uses isr to trigger usb data transfer.
Also, I am confused about two issues:
1. How does OMAP side data transfer to Endpoint FIFO. Does it use loop like:
for int i = 0; i < packet_length; i++
*(TXFIFOADDR +i) = * (src + i);
2, How does Endpoint FIFO send data to host? Does FADDR = set_address work, where set_address is address send by host?
Any suggestion is welcomed. Thanks!
