I've recently been testing using the F button to start and stop the RPi when connected via the USB Power supply.
When I press the F button, the UPS correctly triggers shutdown, and the red LED on the pi as well as the solid SYS LED on the UPS are on. However, after the FFSD timeout (30s) the UPS enters LPR mode (SYS LED goes Off), and as soon as it does, the RPi reboots with the UPS still in LPR mode (no LEDs on).
If I just leave it, the RPi will happily work, but with no UPS functionality.
If I press the F button at this time, it hard resets the RPi and reboots it with the UPS working correctly again.
I have a couple of other hats on the RPi board. I am wondering if their power draw in LPR mode is somehow confusing the UPS and triggering a restart? or is the just he RPi?
Could you please help?
Thanks
Hi,
Please advise firmware version, hardware configuration (what other HAT are used if so) as also what Raspberry Pi you are using (model) in order to support you.
Thank you and Kind Regards
Hi
The firmware is 0x179, which I upgraded yesterday to attempt to see if it would fix it. It did not. I also tried it on firmware 0x156. I am using a HV4B with a LiPo. Reset and power pins are connected to the RPi via two small leads. I've been using a contact button to short the F button & Ground on the external button connectors, but the behaviour is the same with the on-board F button.
The other hats are:
MCC 172 DAQHAT ( https://digilent.com/shop/mcc-172-iepe-measurement-daq-hat-for-raspberry-pi/?srsltid=AfmBOop88RxfO6Y43Hb3NvsQSFIqwQBJd2rqci98O9ioW7vvtP_at67u)
The MCC 172 is also connected permanently via USB.
The Raspberry Pi is a 4B running Raspberry Pi OS x64.
Thanks
Hi. Are you able to help? I haven't heard back.
Thanks
Hi,
Yes, I reproduced it here with version 0x0179. Working to correct it. It is a bug

Hi Pi Modules Team
Thanks for confirming.
Any updates on when a new firmware might be released?
Thanks
Hi,
This week. Please also download new setup registers script we released before 3 days
BR PiM
Hi
I downloaded the new registers setup script from the firmware page, pico_setup2.6_hv4.0.py but it tells me I need firmware 0x0180. Where can I find 0x0180 firmware? It doesn't appear on the firmware download page.
Thanks
Hi,
It has been not released yet. However the script is proper and working also with 0x0179. Until we release the 0x0180 please edit the script and change the 0x0180 to 0x0179, and everything will be working well.
See below

Thanks for the help. I've made that change and successfully run the script.
I am not sure what settings I am meant to change to stop the above behaviour. Could you please give me some direction?

Hi,
This script has been written (by the way by CHATGTP and polished by us), in order to simplify changes of the PIco registers. As most of the people have had some difficulties to change any register, we made this script that is doing that job much easier. I was thinking it is very initiative i.e. instead of writing
sudo i2cget 0x6b 0x07 to check the value,
and then set the new one i.e.
sudo i2cset 0x6b 0x07 0x49
You just run the script, select what register you need to change, see the current value, you are advised what value are allowed, write it and that's it, see again what has been changed
Hope you enjoy it.
Must say that without CHATGPT I would be needed couple of days to write it, now it has been done in 24 hours. New nice and very efficient era is coming for us.
My Best Regards
PiM (Pi Master)
