PiSCSI service fails to start, "Illegal instruction"

[ktaggart]

Hello,

I purchased my kit quite a while ago, and for many reasons, didn't get around to putting it together/setting it up until recently.

As the title indicates, after following the instructions (https://github.com/PiSCSI/piscsi/wiki/Setup-Instructions), the result of the build process (easyinstall.sh)is that the resulting files are generating an illegal instruction error.

My hardware is the RaSCSI v.2.4a (full spec) with the Pi Zero W v1.1.

Any insights would be helpful.

Would you be ok running a slightly older Raspbian OS version? We officially only support Bullseye.

We have pre-configured images ready to be flashed on an SD card in the releases section.

Thanks for the response, is there a specific version you would recommend?
