"Ungültiger Maschinenbefehl"

[TomCat112]

Hello,
i made the installation like you descripe in the wiki. After all i trie to test it. But with the parameter -D i just get this output:

Registering demod for TFA_1 KlimaLoggPro
Ung?ltiger Maschinenbefehl

What can be the fault?

Thanks for your reply and thank for the great work

Sound like compiling for the wrong CPU, but maybe it's a real bug. Can you enable the -g debug-option in the makefile, "make clean; make" and run it again in gdb? Then the stack trace of the crash can optained by "thread apply all bt"

I had a similar error trying to get tfrec run on my Raspberry Pi Zero W.
Solution is to adjust the CXX flags in the Makefile:
..
CXXFLAGS=-O3 $(PROFILING) -mfpu=vfp -march=armv6 -mfloat-abi=hard -ftree-vectorize -ffast-math
...

Details about compiler flags for different Raspberry models can be found in the raspbian FAQ or here

Have a great day,
Robert

There is now a adapted Makefile.raspi2, should also work for the Zero
