AGILEX 5 cvp mode

Hello,

I'm using the Arrow Eagle board and trying to use CVP mode. I've flashed the JIC file and am now trying to upload the core.rbf file using this command

echo <filename>.core.rbf > /sys/kernel/debug/fpga_manager/fpga0/firmware_name

but the directory /sys/kernel/debug/fpga_manager/ does not exist.

I noticed that the directory /sys/class/fpga_manager/fpga0/ exists, but there is no firmware_name file

ls /sys/class/fpga_manager/fpga0/ =>

device/ name power/ state status subsystem/ uevent

How can I resolve this issue?
