Hi
i have a problem
I'm trying to implement a loop back similar to exemple bulkscr but i want not to use the autopointer for copy endpoint out to enpoint in (for read my write). I would like access to ram by make the copy directly.
I tried to use the command
for (i=0;i<512;i++)
EP6FIFOBUF =EP2FIFOBUF; // EP2 OUT and EP6 input
but doesn't work
is the assigment correct for fifo ram buffer?
thanks a lot

Hi,
Yes, you can access the fifo contents by firmware but FIFOshould be configured for Manual mode. For more details on manual and automode please look into section 9.3.4 Auto-In / Auto-Out Modes of TRM-page 111. You can configure FIFO modes using EPxFIFOCFG register.
