Re: Wake from halt

Is there any way to configure which GPIO pin is used to wakeup? I am working on a CM3+CMIO3, and both GPIO1 and GPIO3 are occupied (I'm using the dpi24 overlay). I am able to shutdown via the gpio-shutdown overlay, and wake by grounding the RUN pin. But it would be ideal if I could configure the sa...

Re: Raspberry Pi Zero overclocking

Can you over clock a pi zero w? (sorry for not making a new thread) My RPI0W runs at 700 MHz. (as does all zero w I assume) Also is there going to be an update to the raspi-config to allow for zero w to be OC without editing the config.txt? It runs at 700MHz when idle and 1000MHz when busy (the cor...

Re: Kodi does not start on PI 3

OSMC has separate images for Pi0/1 and Pi2/3. You need to run the correct image.

For help in transferring existing setup to the new Pi2/3 image you should ask here:

Re: OpenArena package

its not running at all is there a fix for this? It probably uses the firmware gl drivers (e.g. /opt/vc/lib/libEGL.so) which have now been renamed to /opt/vc/lib/libbrcmEGL.so). Ideally the openarena package should be rebuild with new libs names. For now: cp /opt/vc/lib/libbrcmEGL.so /opt/vc/lib/lib...

Re: Interpreting get_throttled=0x10000 or 0x30000

How should I interpret get_throttled=0x10000 or 0x30000 ? 0x10000 means low voltage has occurred 0x30000 means low voltage has occurred and arm frequency has been capped (due to temperature over 80'C). Normally low voltage will trigger throttling of turbo, but that can be disabled with "avoid_warni...

Did you enable the (experimental) GL driver? It's not compatible with omxplayer (or anything else using the GPU).
Setting gpu_mem=16 would be another way of stopping omxplayer working in this way.

If you are running latest rpi-update firmware then no need for total_mem=1024 in config.txt. The extra 16M will be available.

Re: Under-voltage warnings

If the power drops below the voltage threshold are brief (e.g. a few milliseconds) then you won't spot it on the LED.
But get_throttled has some persistence (matching the visible warning symbol) so it will show any undervoltage events that occurred recently (~ 1 second).

The seting max_framebuffer_height helped. What was not expected: when the virtual height was set to 2401, the physical height was set to 2400 instead of desired 1200. Expected: set the virtual height to 2400 and don't touch physical height I've had a closer look and I have seen something suspicious...

Re: New firmware works bad when virtual framebuffer height >

That is expected behaviour. We consider the 1920x1200 the maximum supported framebuffer resolution. We allow up to double the maximum supported dimensions for a virtual framebuffer (e.g. 3840x2400). But you can change these limits. Try setting, e.g. max_framebuffer_height=1600 and you should be able...
