Hi,

I understand that you want to send the same data from the P port to both USB and SD sockets. This is called a multicast channel.

To implement a multicast channel, please refer this example project

C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\dma_examples\cyfxbulklpmulticast

-->exactly right,but i want to read sd card data in the pc also from control center.

means...

1)p port->u port

2)p port->s0 port->u port

once at a time,

is it possible??
