Segmentation fault when using ReadPipeUIntArray via Python

tschue-nxt — Mon, 20 Jul 2026 11:14:26 GMT

Hi,

I am running into issues currently where I want to use a pipe to stream data packets (header+payload) from target to host.

When using ReadPipeUIntArray to read the binary data I am running into fmlite crashes frequently. I attached a python example and fmlite output as reference.

Thanks in advance

Hi @tschue-nxt,

Could you check the attached fmlite binary and let us know if it works in your case.
