[Agilex]:Error Sending Bitstream..!

Dear Experts,

We are currently working with the Agilex 7 F-Series SOC Development Kit and following the steps outlined in the provided link:
[Agilex PCIe Root Port | Documentation | RocketBoards.org]

However, during the Linux boot-up process, we are encountering the following issues:

“Error sending bitstream!”
“FPGA image is corrupted or invalid.”
“SCRIPT FAILED: continuing…”
" Unable to read file / "

It’s important to note that we are booting from an SD card and using the prebuilt binaries for the PCIe Root Port reference design.

We would greatly appreciate your assistance in resolving the issue and ensuring a successful boot-up process.
