Illegal hardware instruction

[B3nMo]

I installed a Manjaro on my Surface Go, with linux Surface kernel on it. Everything works like a charm except the stylus pen. It turns out that the iptsd daemon (actually, all binaries of the ipts project compiled so far, in any version) fail with an "illegal hardware instruction (core dumped). Any idea how to diagnose this? Thanks.

The Surface Go line doesn't need iptsd, the touchscreen is fully supported by the upstream kernel.

[..] except the stylus pen [..]

I know the question is stupid, but have you checked if the pen is charged?

Thanks a lot for your reply. Your question is not stupid ; actually, I was considering testing the pen at my favorite store before entering my loop of failures... ;-)
