Hi all,

I am developing usb serial interface for sam9263-ek. I ported the code from SAM7 example to u-boot. I am currently facing problems in SendData function of cdc_enumerate.cwhich i think may be a synchronocity problem with CSR register. Can anyone please may be tell me if you know some special cases where such things occur. I also used sniffer "USBTrace" in the host side and found that there is no "IN" packet received by the HOST at all even though in the device side the data is written to the FDR. If you can throw some light and give some pointer where to check that wil be a great help.


Thanks,
Krishna.
