Have been messing about with my 2Gb RAM RPi 4B in preparation for use on future projects.
Experiencing an issue which I have not had to date with any previous RPi models or program software.
Running the latest Raspberry Pi OS (based on Dabian Buster I belive), full desktop program version, running on either a 16Gb. SD card or a 120Gb. SSD with suitable USB-3/SATA adaptor.
Also using a Pimoroni "Fan Shim" cooling fan with associated SW loaded to control the fan operation at pre-set temperatures.
Static LAN and Wi-Fi IP addresses are configured.
Samba is installed and configured to make the RPi visable on my Win 10 desktop PC via explorer.
VNC and SSH options are also activated for "headless" operation.
With the exceptions of adopting the Raspberry PI OS operating system and the cooling fan temperature control software, nothing I have not done before on previous RPi models without any issues.
Did previously change the "boot loader" FW to a beta revision which was a requirement at the time to enable native USB booting & running from a USB-3 attached SSD (via SATA adaptor), have since changed this to a "stable" current version boot loader which now supports this function.
The issue I'am experiencing:
The RPi appears to "lock up" after quite a long time of idle operation, usually occurs after 24 to 36 hrs of running.
Occurs when running on SD card or SSD.
Won't boot up again after power down or re-boot.
Only solution to restore is re-loading of SD or SSD images which I had kept after initial configurations.
In order to try and find the issue, have re-loaded an SD card, fully program updated and only installed static IP configuration & Samba, under longer term testing at present.
Can't find any record of any such issue on the RPi forums, wondering if anyone has had any recent similar experience ?
