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

Hi Aik Eu,

Sorry for this late response. Thank you for your last suggestion regarding using "fpga load".

It could work, and I can use it, but I would have to know in advance the size of the fpga file to be loaded, so it's just like using a header that contains that information.

The thing is, I upgraded the Uboot version I'm using from Uboot 2014 to Uboot 2020.

In Uboot 2014, you could load the RBF files without a header, and in Uboot 2020, you have to wrap the RBF files with a header before loading them.

I want to know if in Uboot 2020 I can still load, in some way, the RBF files without a header, and that is the main thing I'm trying to understand. Maybe I can't, and they changed the way Uboot works, so without a header (or knowing the RBF file size), you can't load the FPGA file.

I want to know that because it affects the way the RBF will be given to me. I receive them from someone who, until now, has produced them without a header since he doesn't know about uboot and its mkimage tool.

(I can say the excat uboot command where the calling to header exists in Uboot 2020 if it will help.)

(By the way, I looked at the Uboot information about it. That from this and this version, you have to start using a header, but I couldn't find anything.)

So that's what I'm trying to understand. So I'll know how to act from now on regarding it. Maybe he would just give me the RBF files, and I would add a header to them each time, although I less prefer this option.

Thanks again for trying to help.
