@ABelliqueux : I've got the same error, but after a reboot it launches without any error:
pi@raspberrypi:~/PiFmAdv/src $ sudo ./pi_fm_adv --audio sound.wav --freq 103.3
Carrier: 103.30 Mhz, VCO: 826.4 MHz, Multiplier: 15.303704, Divider: 4
Allocating physical memory: size = 4354048, ioctl_set_msg failed:-1
mem_ref = 4354048, bus_addr = 3, virt_addr = 0x7f985d8003
Master PLLC Locked
Outputting signal on GPIO 4.
It emits on the default freq but without any sound and the rpi 4b crashes.
Edit: I finally succeeded with either https://github.com/ChristopheJacquet/PiFmRds and https://github.com/markondej/fm_transmitter on a low frequency (<92MHz).
Running on a rpi 3b, running Debian 12 Wormbook, Linux 6.1.0-rpi7-rpi-v8 aarch64.
I've added
gpu_mem=250
to /boot/config.txt.I built successfully but when trying to run, the program instantly exits 'cleanly' after
Outputting signal on GPIO 4
, no matter what arguments I use :After running either of these commands, with a radio tuned to the right freq, it makes the white noise go away, until I reboot the rpi.
I can play and hear the sound file fine with
aplay
via the jack output. I've checked for modules that use the GPIO, but found none.Is there something else I should be trying ? How can I get a more verbose output ? Any idea ?
