Building Android 4.2.2 from source for A20-OLinuXino-LIME (no NAND)

[NK]

I have successfully setup the environment for compiling Android 4.2.2 from the source for A20-OLinuXino-MICRO. and able to compile both kernel and Android 4.2.2 sources.

I read the blog posts https://www.olimex.com/wiki/A20-OLinuXino-MICRO and http://axonjakarta.wordpress.com/2014/02/14/olimex-a20-android-building-4/

When I try booting from SD card, I get following error in serial debug port:
My sys_config.fex file has storage_type = 1
I still see boot-loader trying to detect NAND. How do I disable this behavior?


Can anyone share working sys_config.fex and sys_partitions.pex files for A20-OLinuXino-LIME (no NAND)?

I have copied image file using dd command :
sudo dd bs=1M if=./lichee/tools/pack/sun7i_android_olinuxino-a20.img of=/dev/sdc1
Is this the correct way to copy img file to SD card?

May need /dev/sdc

Thanks John,
I tried that too. Also used PheonixCard to burn the SD. Still get the same boot-loader error

Finally, I got it working.
Used PheonixCard tool from windows, did the following steps:
1) formatted the card with "write mode" set to "Startup !"
2) used "burn" option with "Startup !" selected to write sun7i_android_olinuxino-a20.img

Now I have a working Android compiled from the sources

Excellent!
