Hayati Ayguen h_ayguen at web.deHello, now tested the binary compiled on RPi 1 on the RPi 2 - after copying the full source including build directory of cmake and executing "sudo make install" on the RPi 2. The result: this works fine! Do i have to conclude, that Raspbian's g++/gcc compiler does produce wrong code when executed on RPi 2 ?! gcc/g++ (Debian 4.6.3-14+rpi1) 4.6.3 OK, now verify: make clean, rebuild and install new binary (from the build directory copied from RPi 1): this works! but, i don't understand why! Now reboot, so that kernel module reloads: still works! In the end, i'm happy that it works "somehow". But, i've no idea where the problem lies! kind regards, Hayati Am 08.07.2015 um 09:38 schrieb "Hayati Aygün": > > Hi Marcus, > > librtlsdr is OK, because rtl_tcp works fine, which transfers full I/Q > spectrum of ~ 1.4 MHz to SDR# on Windows/PC. > The problem must lie in rtl_fm.
