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 port to FPGA's passive serial configuration port and in the linux device tree I added following lines:

 

&ecspi1 {
    status = "okay";

    altera_spi: altera_spi@0 {
            compatible = "altr,fpga-arria10-passive-serial";
            spi-max-frequency = <40000000>;
            reg = <0>;
            nconfig-gpios = <&gpio5 0 GPIO_ACTIVE_LOW>;
            nstat-gpios = <&gpio4 31 GPIO_ACTIVE_LOW>;
            confd-gpios = <&gpio4 20 GPIO_ACTIVE_LOW>;
            status = "okay";
        };
};

 Our linux systems (Kernel v5.4) boots fine. Under the /sys/class/fpga_manager folder, I have:

 

root@localhost:/sys/class/fpga_manager/fpga0# ll
total 0
-r--r--r-- 1 root root 4096 Sep 23 12:38 consumers

-r--r--r-- 1 root root 4096 Sep 23 12:38 suppliers
-rw-r--r-- 1 root root 4096 Sep 20 10:44 uevent

 

Now any idea how can we send our rbf file into the FPGA? I couldn't find any documentations or help for the rest of the operation.

 

You helps are highly appreciated.

Thank you.

Hi,


Do you have any further update?

Hi,

 

Thank you for the guideline, it was really helpful.

 

But in our case we don't have fpga0 in our /dev folder to use it with dd if=soc_system.rbf of=/dev/fpga0 bs=1M command as suggested in the link you provided. 

 

Is there any particular field in the device tree file to have fpga0 in the dev folder?

 

Thank you.

Hi,


Unfortunately, that was the old flow for reference. Because the FPGA cannot be configured from Linux. If you need to define or change the fabric behavior from Linux, you must use PR (partial reconfiguration).


But may I know the reason to configure the FPGA via Linux? For newer flow, you need to read the description here:

https://rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Appendix_45_Reducing_Arria_10_Fabric_Configuration_Time

Hi,

 

Like I mentioned at the beginning that we have a product which has iMX8M-Plus processor with an Arria 10 GX FPGA. We are not using Arria 10 SX SoC. 

 

We connect Passive Serial Port of Arria 10 GX FPGA to SPI port of our iMX8M-Plus processor.

It is very possible to configure Arria 10 GX FPGA fully through its Passive Serial Configuration port which will be controlled by Linux at the end. 

 

My question was about how to use fpga-arria10-passive-serial driver available in the latest linux kernel developed by Altera. And unfortunately my initial question is still valid.

 

Thank you.

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):


https://rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Appendix_45_Reducing_Arria_10_Fabric_Configuration_Time


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

https://www.intel.com/content/www/us/en/docs/programmable/683034/current/partial-reconfiguration-with-the-hps.html

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

https://www.intel.com/content/www/us/en/docs/programmable/683461/current/passive-serial-single-device-configuration-92795.html

 

Thanks.

Hi,


Thanks for the info, I have confused myself with the question, I get your inquiry now.


I need to check with our configuration expert on this issue, I will get back to you once I have the info for you, regarding configuring your A10 GX FPGA when your hosts boot up, if this is possible.

Hi,


Unfortunately, we do not have a direct documentation for this example.

The connection need to be like in the link you have shown previously:

https://www.intel.com/content/www/us/en/docs/programmable/683461/current/passive-serial-single-device-configuration-92795.html


Since you are using you own processor to do configuration, you may need to use JAM player. Running C coding from your processor to interact with FPGA.
