PiFmAdv on Raspberry pi 4 #72

Closed haiko1994 closed 2 years ago

haiko1994 commented 4 years ago

Hello All!

i'm new here and my english is also not the best but i try to do my best. I hava bought an Raspberry pi 4 and want to install the PiFmAdv. But when i try to start the application i get a error message 'Warning: Master PLLPA Not locked' and i get no music on the selected Frequency.

Is there someone who as a solution or the samen problem?

miegl commented 4 years ago

The PLLA (Auxiliary PLL) is used for the camera interface, but changing its frequency can also collide with video from my experience. That's why I usually recommend running the Raspberry Pi headless (i.e. without graphical interface). Perhaps describe your setup a bit?

I'm having the same issue. I'm using image 2020-05-27-raspios-buster-lite-armhf.img with no camera or desktop installed config.txt

Can you try commenting dtoverlay=vc4-fkms-v3d ?

pwrobot commented 4 years ago

I am having the same issue with my PI 4B saying "Warning: Master PLLA NOT Locked", have you been able to find a solution yet?

mobluse commented 3 years ago

I have the same issue with "Warning: Master PLLA NOT Locked" on Raspberry Pi 4 B 4GB RAM and no sound or RDS (the same FM-radio in Android phone works fully with PiFmAdv on Raspberry Pi Zero WH):

I run pi_fm_adv after having rebooted after changing config.txt to this (no known config.txt works for me).

Fixed in https://github.com/miegl/PiFmAdv/commit/9f4cbc32d9361527d3d5f40c18a9f1b8150dcfa2 PiFmAdv now default to using PLLC, PLLA doesn't seem to work on Raspi 4 (it can be enabled with --pll a).
