Arria 10 configuration through Linux fpga-arria10-passive-serial driver

Hello, We have a products which has iMX8M-Plus processor with an Arria 10 GX FPGA. We want to configure FPGA each time when our embedded system boots. To do that we have connected a SoM SPI p...

Hi,


As mentioned, you need to use Partial Reconfiguration, in order to be able to configure the FPGA via Linux, as the fabric cannot be configured from Linux. If you need to define or change the fabric behavior from Linux, you must use PR (partial reconfiguration):

Thus, to answer your question, please refer to below:

Hi,

Thank you for your effort but, we are not using Arria 10 HPS.

We have Arria 10 GX which doesn't have hard processor system (HPS).

And with the GX, it is possible to use an external processor with Linux and configure GX through Passive Serial Interface as shown at below link:

7.2.2.1. Passive Serial Single-Device Configuration Using an External Host

Thanks.
