Hello all. I have an 8GB SD Ubuntu Linux image that I am trying to copy over to the eMMC area and have it boot off of that.
The image works, being that if I burn the image to another 8GB SD card like this:
“dd image.img.Z bs=4096 | uncompress | dd of=/dev/sde bs=4096”
It will boot from the card correctly. But if I copy it to the eMMC (using a larger SD card with the image on the card) and the command:
"dd image.img.Z bs=4096 | uncompress | dd of=/dev/mmcblk1 bs=4096"
and then try to boot from the eMMC, I get this:
C3hswitch frequency to 0x000000046
frequency divider is 0x00000080
switch frequency to 0x000000046
frequency divider is 0x00000004
switch to SDR 8 bit
switch bus width to 0x00000008 bits success
…and it just sits there.
does anyone know what is going on?
Please help, and thank you in advance.
Ok - no matter what I do it will not boot an ubuntu Linux partition from the eMMC. I did a kind of ‘work around’: within the boot partition of the SD card I made it switch over to the eMMC for the ROOT partition. Once it’s booted, you can take out the SD card.
I’m not crazy about this solution as it’s a little kludgy (I’d rather it boot directly from the eMMC), but at least this works. :-/
