A heads-up for anyone who uses a push button to toggle their pCP on and off: there's another new feature in the RPi 4B. The halt command apparently puts the device into a very low power state, from which it can no longer be woken by grounding GPIO3. One of my front panel buttons is dedicated to doing a safe shutdown (using the pCP shutdown overlay), and I had used GPIO3 for this specifically so that the same button could be used to wake the device.
There is a way to reinstate this behaviour though. 'This post' (https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=244165#p1495167) on the Raspberry Pi forum details how to tweak the on-board bootloader. The downside apparently is that after this tweak the 4B will draw more power once halted than the 3B does, but in my case I felt that the benefit of being able to toggle the 4B on and off with the same button outweighed this extra current draw, since my 4B will rarely be halted like this. So I went ahead and applied the tweak, and now the old behaviour is working again. ------------------------------------------------------------------------ chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=110727 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
