I have been trying to build an FPGA image on my STEMLab 125-10 (following the docs from Red Pitaya here) for around 6 months now and at my current state I cannot get past the Makefile.x86 install command.

I have the entire ecosystem installed from 3.2.2.4.2, however, after calling the settings.sh and disabling the library overrides, I run

Code: Select all

make -f Makefile.x86 install MODEL=Z10

which throws a bad value error for the '-march=' switch, with a small snippet of the error shown below:

Code: Select all

I have tried looking for the source of the error within the code so that I may change it, but I can't seem to find it, and the solutions I have found (namely this solution from Nils Roos) have not worked for me. Any help would be greatly appreciated!

For reference, I am running WSL with Ubuntu 22.04.1 LTS on a Windows 10 desktop.

Hi

I see that you are using the wrong compiler to build the kernel.
You have a gcc compiler for the x86 architecture, but you need it for the arm architecture

You can used scripts for easy build ecosystem
https://github.com/RedPitaya/RedPitaya/ ... ld_scripts

Apologies for the time since you replied, I have been bogged down by my other college work.

In my case (as detailed somewhat in my original post) I have succeeded in the automatic build process in 3.2.2.4.2 as detailed here. I.e.,

Code: Select all

cd ./RedPitaya/build_scripts
sudo ./build_Z10.sh

worked as expected.

So are you saying that if I have already ran the build script to completion, then I don't need to do anything else with the Makefiles? I.e.,

Code: Select all

make -f Makefile.x86 install

or

Code: Select all

make -f Makefile.x86 fpga

is redundant and will not work based on my architecture.

If so, I appreciate the input. Otherwise, please elaborate on your post. I am not super familiar with Linux other than my work done with the Red Pitaya, so architecture aren't quite as intuitive to me.

We forwarded the question to our developers. Unfortunately, there will be some time until they can answer as they are on vacation.
