How to use LW HPS to FPGA Bridge in Arria10 HPS?

[sunyeong]

Hello,

I am trying to implement some features using Bridge interface.(Lightweight HPS-to-FPGA)
The "bridge enable" command in u-boot didn't work properly.
So, I modified the device tree and I can see that the command was operating properly.
And then I wrote application to control led_pio to verify whether bridge is working properly. But, it's not working properly.

Can you give me a guide about using this bridge feature?
(Chip/SoC: Arria10,  linux kernel version: 6.1.68)

I attached device tree and application that I modified or wrote.
(arch/arm/boot/dts/socfpga_arria10.dtsi)

Although the Bridge feature is a basic feature provided by the chip,
there are almost no examples or guides to verify this feature.

Regards,

Jung
