Today I try to run Debian from microSD on RK3188-SOM, but unfortunately without success :(.
I downloaded 7z archive from provided torrent.
Un7ziped it, and got RK3188_debian_3.0.36_SD_release1.img almost 2Gb file.
Wrote it by execute to my 32Gb microSD:
sudo dd if=RK3188_debian_3.0.36_SD_release1.img of=/dev/sdb conv=sync,fsync
And after insert this microSD in RK3188-SOM, I got:
DDR Version 1.04 20130517
Bus Width=32 Col=10 Bank=8 Row=15 CS=1 Die Bus-Width=16 Size=1024MB
FwPartOffset=2000 , 0
run on sd0
SecureBootEn = 0 0
Boot ver: 0000-00-00#0.00
What am I doing wrong? May be I need to set some offset by seek or something else?
Does anybody try this omg?
Partition table on microSD after wrote RK3188_debian_3.0.36_SD_release1.img:

1. What happens when you try with just "sudo dd if=RK3188_debian_3.0.36_SD_release1.img of=/dev/sdb" ? Can you confirm the SD card reader is identified as /dev/sdb ("ls /dev/sd")?
2. Try to download and extract the image again.
3. Power the board sufficiently it might draw a lot of current at certain points during boot-up.
4. Do you also use RK3188-SOM-EVB or just the RK3188-SOM?
LubOlimex, thank you for your fast reply, the first point do the job :).
If I wrote microSD with next command:
sudo dd if=RK3188_debian_3.0.36_SD_release1.img of=/dev/sdb
"RK3188-SOM Debian for microSD card - kernel 3.0.36+ - release #1" img works as expected.
