Issue with "RK3188-SOM Debian for microSD card - kernel 3.0.36+ - release #1"

[ych]

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:

Code Select Expand


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:

Code Select Expand

What am I doing wrong? May be I need to set some offset by seek or something else?
Does anybody try this omg?

Hey,

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?

Best regards,
Lub/OLIMEX

LubOlimex, thank you for your fast reply, the first point do the job .
If I wrote microSD with next command:

Code Select Expand


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.
