ZC706 PL receive data from PC

[wzy96321]

Hi,

    I find the Uart and Etherenet PHY only in PS.So Is there any other way to receive  data from PC to PL？ IF no，can the J63 ( the XADC  header)or other interface external a uart to USB circuit toachieve it？

                                                                                                                                                                             Regards,

you can have an Ethernet IP on the PL but I don't think it's practical. If I had to use Ethernet I would use the one in the PS and DMA data to the PL as needed.

Alternatively, you can have a Microblaze and a UART interface. Much lighter. It all depends in the amount of data and complexity of the link.

The amount of data is little , Use Microblaze ,mean have to use PS,it can't transmit data between ZC706 board and PC by PL(use verilog code to achieve it) only?

For small amounts of data I wouldn't take the burden of Ethernet.

Microblaze is not exactly PS, it resides in the PL. It requires software, yes, but I think you can't get away without that. If you are brave enough, you could try some HDL, but I think you'd end up doing the same but from scratch.

Thanks,looks like it's going to have to be done PS+PL.
