LattePanda - Lakka stuck on flower at boot


#1

Hi, Can anyone offer any advice on getting Lakka to run on a 2GB lattepanda please?

I have seen 1 youtube video which shows it running on a development build but no details on which one.

I presume my problem is a graphics driver issue Are there any bootloader options I need to enable?

Many thanks in advance Phil

Same problem here. Stuck at the flower screen.

Former owner of the LattePanda board here. I do believe you have to disable the UEFI boot sequence and enable it to Legacy instead in order to do the proper installation to the eMMC module on board the Lattepanda in order for Lakka (or any Linux builds for that matter) to work properly. Go into the LattePanda BIOS/Setup upon booting and try changing that first. Then install Lakka onto the eMMC and try booting it up.

Thanks very much for responding.

I was trying to run Lakka from a pen drive at least to start with, and see what the performance is like , however if eMMC is the only way it is going to work I am willing to erase Win10 which is currently on the internal flash.

I have flashed the “linux compatable” BIOS for the LattePanda, and I can succesfully boot live Ubuntu from a pen drive.

The youtube video I mentioned earlier is running Lakka from the pen drive, with a development build, however the poster seems to be unwilling to share how he achieved this.

If you’re referring to ETA Prime’s video for the LattePanda: https://www.youtube.com/watch?v=POJxmI3HPF0

gouchi was the one who provided the build I believe. ETA is also a member of these forums, so you can hit him up directly if you wish. But the LattePanda builds are the LibreElec-based builds you probably should look here (and referring to booting from the pen drive, initially, I did have a hard time, but did get it to work eventually, but forgot how, and sold off my LattePanda board later on): http://nightly.builds.lakka.tv/


#6

Thanks for responding.

Just to clarify… I’m looking in the experimental LE master directory and choosing a Generic X86 build?

Many thanks for your assistance

Phil

That’s what I would try. NO guarantee of success, but that is what I tried.
