HI @Akira

I managed to boot ubuntu on the board, and i think the problem was the display, I connected the board with my tablet via HDMI and i thought it will work, but i think it is the problem.

Now i am searching for an alternative way to display, I think i am gonna use RCA

I found some HDMI to RCA cables with a box and power and some without power like the attachment, which will work with my Dragonboard 410C ?
*I have also an HDMI to micro HDMI

HDMI to RCA without power box

Hi @Hathout,

Nice!
Great that ubuntu is booting on your DragonBoard 410C.

For the display, honestly I never had a good experience with the HDMI to RCA cables for me in the past.
I used these kind of HDMI to vga converter for a none HDMI display.

It worked for me.
