C5515 data transfer 6kbytes

Pierre-Alain Conus
Prodigy 20 points

Hi All,

I work on C5515  with  Csl LOW-POWER 3.00.00.02.

I started with CSL_USB_DmaExample_Out and I changed endpoint 1 and endpoint 2 to interrupt mode and i am able to transfer 63 bytes of data.

I use USB_postTransaction to initiate transfer which works for data size 63 bytes, but when i try to increase data size  it cuts after n bytes  specified in descriptor, max packet size.

Could you please tell me how to manage multi packet in order to transfer data size greater than 6 kbytes ?

Thank you for your help

Best regards,

Pierre-Alain
