I found the Debian OS released by ESWIN, Release Debian-v1.0.0-p550-20241230 · eswincomputing/eic7x-images · GitHub, I installed the image and it can support more much functions like LLMs, video processing, etc. It is amazing and makes the P550 board more attractive.
Share the link here, grab it and have a try.
It seems worth a try, but I’m afraid that I couldn’t make it back to ubuntu . thanks bro.
@RviWW, you will be able to re-flash the board with Ubuntu by following instructions in “HiFive Premier P550 Image Update Procedure” at the link below. However you should backup any data on the eMMC before you flash the Debian image.
