Unix Communication Driver between A53 and FPGA Xilinx eval board ZCU102

Hi,

I am looking for an interface AXI (Linux driver) between A53 and FPGA for ZCU102 Rev 1.x board.

I searched github repos and forum but could not locate. Your quick help is sincerely appreciated.

Regards,

Milind.

Hi @Milind 

 

What do you mean "Unix Communication Driver" ?

Did you refer uio driver and mmap ?

If my understanding is correct, you can use uio driver or mmap to achieve what you want to do.

Dear sir,

I looking to (communicate) do the data transfer A53 ARM processor to FPGA and vice-e-versa , I have Ubuntu OS on my SD card and looking for device driver which can be called by my file transfer program to transfer data (by passing) OS (using kernel).

If uio and mmap is helpful then I will look at those drivers.

My apologies, I am very new to this Xilinx boards (I've experties in Unix)

Kind regards,

Milind.

Hi @Milind 

 

I suggest you to use DMA driver in this case.

Would you refer it ?

Also, there are relevant information. Would you refer, too ?

Thank you sir..

To simplify my request.. 

I have a Xilinx Zynq UltraScale+ FPGA with ARM A53 processor board (part number XCZU19EG-2FFVC1760E).

I need a Linux based driver that will allow me to communicate between the A53 processor and the FPGA over the AXI bus. 

Please let me know where/how I can get a copy of this driver.

Regards,

Milind.

Hi @Milind 

 

> Please let me know where/how I can get a copy of this driver.

 

Sorry. I don't understand it.

Did you try kernel config to enable ex. DMA driver by ex. petalinux-config command ?

If no, would you refer this document ?
