Hello,
Fresh install of the Raspberry Pi OS 64bits on a Rpi 4B using the latest image (i.e. 2023-12-05-raspios-bookworm-arm64.img.xz).
Install latest Witty Pi's software. Reboot the Rpi => no problem.
Update packages using "sudo apt update" and "sudo apt upgrade". Reboot the Rpi => shutdown immediately after startup.
Here is the wittypi.log content (packages upgrade between 22:31:47 and 22:43:44, Witty Pi removed at 22:44:07):

Sorry, I didn't notice that a new firmware was released a few days ago.
But same behavior with 2024-03-12-raspios-bookworm-arm64.img.xz
No need to update the packages this time. Just burn the image and install the Witty Pi software.

Please double check your connection, Witty Pi's software complained that it can not find the I2C device.
When you Witty Pi gets powered, does its white LED blink?

Connection is OK. I only had to remove the Witty Pi to start the RPi and check the log.
I have used the Witty Pi 4 for months now. There was an issue with Bookworm in January that you fixed with the version 4.14. Everything worked perfectly until recently when I did some updates.
My guess is that there is something wrong with the new kernel 6.6.20
Edit: yes the LED blinks.

Can you boot up your Pi with Witty Pi 4 mounted, by connecting power supply to your Raspberry Pi directly?
If so, you can then run "i2cdetect -y 1" and check if it can see your Witty Pi 4.

The problem is clearly related to GPIO 04:

@jeromebriot Your new log shows no error on I2C communication now. The firmware ID, firmware revision, current output voltage and current etc., they are are values from the I2C registers, which are correctly printed out.
What I see in the log, is that it claimed the GPIO-4 was pulled down, so Witty Pi shut down the Pi. If you didn't tap the button, or short GPIO-4 to GND, then the problem may come from gpio-util again.
You may do this test: enter the wittyPi directory, and then run "sudo ./daemon.sh", if something goes wrong you will see error message on screen.

That's the same error I mentioned in my previous posts. The issue is at line 297 of gpio-util.sh
The script didn't wait for the falling edge to occur on GPIO 04. So the Witty Pi shutdown the RPi immediately.
Note that GPIO 04 is always at 1 (high level).

@admin Here is a quick (and maybe ugly) workaround by replacing RPi.GPIO by GPIO Zero in gpio-util.sh:
doWfi()
{
if [[ $naming -eq $PHYSICAL ]]; then
pin=${PHY_BCM["$2"]}
else
pin=$2
fi
edge=$3
if ! python3 -c "import gpiozero" > /dev/null 2>&1 ; then
echo 'Python 3 or GPIO Zero for Python 3 is not installed, using less efficient implementation now.'
local running=1
local prev=$(doRead '' $pin)
while [[ $running -eq 1 ]]; do
local cur=$(doRead '' $pin)
if [[ ($edge == 'both' && $prev -ne $cur)
|| ($edge == 'falling' && $prev -eq 1 && $cur -eq 0)
|| ($edge == 'rising' && $prev -eq 0 && $cur -eq 1) ]]; then
running=0
fi
prev=$cur
sleep 0.2
done
else
# Python Code Begins
python3 - << EOF
from gpiozero import Button
import subprocess
getPin = subprocess.run(['printf', '$pin'], stdout=subprocess.PIPE)
pin = int(getPin.stdout.decode('utf-8'))
getPull = subprocess.run(['printf', '${PIN_PULL["$pin"]}'], stdout=subprocess.PIPE)
pull = getPull.stdout.decode('utf-8')
if pull == 'down':
pull = False
else:
pull = True
btn = Button(pin, pull_up=pull)
btn.wait_for_press()
EOF
# Python Code Ends
fi
}
It solves my issue. Now the RPi starts with the Witty Pi connected and a click on the Witty Pi's button turns it off.

Had the latest firmware but not the v4.14 (was 4.13) software version. Updated to 4.14 but if it is a transient problem I am not sure it is definitely fixed by it. Will wait and see but if your POC fix makes sense @JeromeBriot I would also love for the uugear team to have a look and fix it in the code :).
Best,
Posted : 16/03/2024 2:48 pm
Just to add I've just updated my pi zero 2 with a witty pi 3 and it's exhibiting the same behaviour. I'm not going to get a chance to test the fix this weekend, but will probably do it on Monday.
Posted : 16/03/2024 2:57 pm
@jeromebriot is that the complete file or just the alterations you've made? I need to update a couple of mine and want to make sure it's right 🙂
