Hello! when i use the USB of C6748 ,i found the example USB_DEV_BULK is too simple to satisfy my project. I need to auto send data to PC when the FIFO is full which is sized when configration. but your example just only use function of USBDBulkInit,without the arguments to config the FIFO the endpoints and DMA,rather than the outo mode.I want to config the registers ,but the work is complicate. SO, can u give me some advice to conplete my peoject ,and give me some examples both the C6748 and the PC,and give me files.

  Thank you!

Have a nice day.

    Hi Qiyou chen,

    I just experimented that USB dev example and able to send a  file of size 12MB from PC to RAMDISK of C6748 LCDK as well as from PC to RAMDISK of C6748  LCDK. If this transfer is able to happen successflly, then the FIFO should definetly be configured to make this transfer happen successfully.

    After detecting the C6748 LCDK board as a USB memory device, did you format it using the FAT filesystem using the Host PC ( Windows /Linux ) ?? 

    Once the formatting is done, you will be able to transfer the data to and fro.

    Below is the screenshot for your reference that the FIFO is configured and active for data transfer.
