External powersource : i tried many powersuplies.
I tried both : the same result
My hdd is detected by the recalbox, i tried an other hdd with the same result.
i use an usb key for roms and sttings saving, but the hdd is only for mobies on Kodi. It was detected by the last releases.
To be honest I'm a bit shocked. Is there anywhere a download for the most recent RPi2 image with Kodi still included? (Oh, and I'd suggest to prominently document such an important breaking change.) My old setup that I wanted to upgrade (on the same hardware which is perfectly fine) dates from 2016. On another RPi2 I have libreelec with a much more modern Kodi. In fact that's the reason I wanted to upgrade in the first place: finally have a less dated UI in Kodi.
