on Arria10, how to load FPGA data that was not generated by UBoot mkimage tool

Hi,

On Arria10 that was build in Altera 20.1 environment, when using UBoot 2020.4 , how can I load FPGA data that was not created by the UBoot mkimage tool?

Currently my UBoot only loads (using QSPI) FPGA data that I generated using the mkimage tool . Generated the FPGA data with a similar command to this one:

tools/mkimage -E -f board/altera/arria10-socdk/fit_spl_fpga.its fit_spl_fpga.itb

(taken from this guide https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10)

When I try to place the RBF files directly on the flash with JTag, when they were not wrapped with mkimage tool it doesn't load and run. In this case they don't have the right header and for that reason it fails (the error message is "No FDT magic number")

What is the command to load FPGA data that was not created with mkimage tool?

Hope I was clear enough, thanks in advance,

Yoels
