Issue with Raspberry Pi 400

Hello! I've been playing around with Kodi on a Raspberry Pi 4 in various guises.

I have a USB-3 SSD which boots to Twister OS and I have Kodi installed with plugins for emby and IPTV. I'd also been playing around with a mSD running LibreELEC and Kodi doing pretty much the same thing. They were both running Leia, but I can't remember exactly which version.

I managed to pick up a Pi 400 and assumed I could just connect the SSD or mSD and it would work in the same way, but when I start Kodi on Twister OS I get a black screen with the small white flashing cursor in the top left corner and the only way I can find to escape that is a power-cycle.

The mSD with LibreELEC won't even boot.

Anyone else had similar problems with a Pi 400? Thanks

Sorry, I wasn't sure if it was Kodi, LibreELEC or RPi issue so thought I'd ask in a few places. I wasn't sure how joined up these things were.

Thanks for your reply. At least I know my Pi 400 isn't the problem and I can fall back to using my Pi4 for Kodi.

The Pi 400 is brilliant though and a real throw-back to the Spectrum 48+ and BBC Electron computers I had growing up. Just incredible to think how much more powerful this thing is and much smaller too.
