CycloneV U-Boot FPGA Load Fails: Code -6

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!
