Hello,

You should be able to read a message by uboot saying that it has read your rbf file loaded successfully.

## Executing script at 02000000

reading system.rbf

3088784 bytes read in 163 ms (18.1 MiB/s)

You can also view your devices on FPGA side from linux, if they are not available, it means it was not configured.

cat /sys/class/fpga_manager/fpga0/state

If you see the output "operating" then your FPGA is configured.

I use a script to load the FPGA image boot.scr, you can use it and test your system. You need to set the rbf name to system.rbf and the device tree file to socfpga.dtb.

Thank you
