Thank you
You also need the latest Raspbian Buster. Your old Pi3 NOOBS card likely installed Jessie or Stretch, which also won't work on the Pi4.

Re: Is it possible to connect to "OCuLink SSD" on Raspberry Pi?

The Raspberry Pi 4 computers can only use micro SD cards or USB drives (so, no OcuLink). Also, the Pi4 does not currently support booting from USB, although that feature will be added in a future firmware update, after network booting. Although, for your company, network booting might be a preferabl...

My 2GB Pi 4B is in one of my old Pi3 2 layer acrylic cases (no sides, so no problem with ports, and lots of airflow). I replaced the noisy, cheap fan with a 40x10mm Noctua, and the system runs cool and quiet with no heatsink.

Re: default 100 meg swap file

Have you changed your system "swappiness" settings? The default of 60 is rather bad for low RAM systems (start swapping when less than 60% of your RAM is free). It's basically the percentage of free memory remaining before swap is used. So the default is to swap with more than half your RAM still av...

It's a pi 3b.
3B is 2.4GHz only, so make sure your are using the SSID and passphrase of the 2.4GHz network. If 2.4 & 5 GHz are using the same SSID, try changing one of them to something different.

How do you know it's not running the OS from USB?
  • Is it not booting at all?
  • Are you trying to boot without the SD card (currently not supported on the Pi4)?

Re: Buster after resize of /root and adding a partition cant boot.

I edited the cmdline.txt in boot partition to match the uuid of sdb2. You also need to edit /etc/fstab with any changes (new partition and PARTUUID). If you are installing Raspbian Buster with Desktop, you could boot up the default configuration, install Gparted and edit the partitions in Raspbian.
