CycloneV U-Boot FPGA Load Fails: Code -6

Hello, I am trying to program the FPGA of my CycloneV from U-Boot. It appears to be failing and I am not sure why. The exact u-boot commands are echo --- Programming FPGA --- echo -----Loading imag...

Hi,

Are you trying to store the kernel or the FPGA image on the flash? (like Nand flash)

I saw this issue before while storing them on a NAND flash. We recommend storing the file system on NAND.

Please confirm.

    with the Cyclone V SOC Development Board

    i have the same issue, loading from u-boot the rbf file:

    => dhcp ${loadaddr} soc_system.rbf
    .....
    Bytes transferred = 7007204 (6aebe4 hex)
    => fpga load 0 ${loadaddr} $filesize;
    Command 'load' failed: Error -6

    But if i compress the rbf file:

    => dhcp ${loadaddr} soc_system_compressed.rbf
    Bytes transferred = 3051080 (2e8e48 hex)
    => fpga load 0 ${loadaddr} $filesize;

    it works

    is there a size limit somewhere ?

    thanks

      I think this is a good question and begs for an answer.
      Running into a similar issue and also speculating about a size limit of .rbf file that perhaps u-boot or the FPGA driver is able to handle.
      Anyone can shed light on this?
      Thanks!
