pcie: fpga: programme FPGA PROM’s

[ Please keep me in CC as I'm not subscribed to the list]

Hi All,

We have a Kintex7 FPGA board connected to Intel Atom PC running Ubuntu
on PCIe bus.
We are looking for a tool to allow us to remotely programme FPGA
PROM=E2=80=99s via the Intel Atom PC on PCIe bus. Does any one already done
this or can someone share the ideas?

Hi

why You do not use jtagplayer from Xilinx?


with best regards

Yes, JTAG can be used. But we have a lot many of these FPGA boards,
using JTAG costs more. And also we want to automate the PROM
programming.

Are you using a Tandem flow? What kind of PROM are we talking about QSPI flash?

Cheers,

I'm not sure about the Tandem flow, can you please clarify me on this?

Okay, we have two onboard PROM=E2=80=99s (Micron=E2=80=99s SPI NOR Flash MT=
25QL128).
The FPGA will be loaded from one of the two onboard PROM=E2=80=99s, it will=
 be
up and running before the PC powers up.
When the Intel Atom PC powers up the FPGA will enumerate over PCIe.
I'm looking for any available Linux tool(user space or kernel space)
to program the PROM's via PCIe interface.

In which case you don't need Tandem. Tandem basically just brings up
minmal bitstream to bring up PCIe link and does the rest via some sort
of partial reconfiguration flow. This allows to meet the PCIe deadline.

Any reason you can't drop a SPI controller in the fabric and use that
to program the FPGA or do you intend to do the initial programing of
the PROM also over PCIe?

No, we use a removeable dongle with a pre-loaded PROM.
