Flash eMMC?

[thomaspfeiffer]

I have two issues with flashing an image to the eMMC.

1) Following http://wiki.friendlyarm.com/wiki/index. ... ux_Desktop i'm able to boot from the emmc. But this works only if there's an additional SD card present. When removing the SD card, i get this error message:

Code: Select all

Card did not respond to voltage select!
** Bad device mmc 1 **
Error: could not access storage.

Is there any possibility to not need an SD card when booting?


2) By using ./fusing.sh, an image is downloaded and used (file rootfs.img). Is there any documentation available if i want to use my own image (eg copied from a working sd card)?

Thanks in advance
Thomas

I was able to answer question #2 myself. Basically you just need to dd the second partition of a working sd card to /dev/mmcblk1p2 (after running fusing.sh).

But i still need an sd card in the slot when booting from the emmc. Any hints on this?
