Second rock 5a doesnt boot

Hello

i have problems starting my rock 5a.
after plugging in the emmc (with ubuntu), µHDMI and power nothing happens.

the green led lights up but there is no output on hdmi.

ive tried 3 hdmi displays, 2 second new rock 5a and various power sources as listed in quickstart guide.

help. whats wrong???

The emmc that came with your rock 5a isnt an emmc but an spi module.
So if you want to boot it use ur own microSD or your own emmc module.
