Please can we see your olad -l 4 logs (I think the ones you've provided will just be -l 3: I assume it was the same electronics and lights (with the same DMX addressing and control data) working on the previous release (was that bullseye)? |

Hi all,
I had a working raspberrypi / ola 10.5 setup thats been running for several years.
However I needed to upgrade to the newest OS (raspian bookworm) and have been unable to get ola to work on this platform.
I've got a https://www.bitwizard.nl/shop/DMX-interface-for-Raspberry-pi bitwizard card.
So I've compiled a 0.10.9 using the process on https://www.lautuscastings.nl/wiki/index.php/Dmx_interface_for_raspberry_pi#bullseye
then I've made sure I've put init_uart_clock=16000000 into the config.txt, theres no bluetooth to disable on this RPI.
my cmdline.txt is just
console=tty1 root=PARTUUID=55a70236-02 rootfstype=ext4 fsck.repair=yes rootwait
my ola-uartdmx.conf is
now the symptom is that the log shows its loading and running:
but the dmx lamps are flickering like they're receiving corrupt or just junk packets of nonsense. But it must be recognisable dmx frames, since they do attempt to display what they're told. I'm feeling like this is symptomatic of a speed mismatch on the uart or something?
At this point I'd appreciate any thoughts or ideas to get this hardware running again.
cheers all,
Rob
