Hi,
I'm runningon a The image was download using Raspberry Pi Manager. I have made the device an AP and installed the Seestar_ALP.
I have also done a apt update and upgrade so I should have the latest everything.
I'm having WiFi and possibly sd card reliability issues.
It will run happily sat on a desk doing "nothing" for days.
When I run an overnight app (in this case seestar_alp) problems start after a few hours and eventually the I loose communication over WiFi. If I plug in an ethernet cable (vis usb converter) I can see the PiZ2W is running.
Having looked around the web there are lots of post regarding the mmc1 controller but I can't find a concrete solution. There seem to be a few from a couple of years ago mentioning firmware but nothing new and as far as I understand the PiZ2W does not have firmware. I believe that it's the Pi4s and 5s that do.
Looking through journalctl I get errors such as:and sometimes a block of Here's a link to journalctl from the last few days..

I have restarted it using power down and some times sudo reboot now.
I have measure the voltage on the Pi and it was 5.01V. It may have not been loaded at the time.
I added to config.txt and I though it had made a difference but then I found similar errors later.
Could some one help me find the issue.
It seems to be around the brcmf device.
Many thanks
Andy
