As a heads up to everyone, this may not work with an SDHC card. u-boot (to=
the best of my knowledge) doesn't support SDHC, even though the linux kern=
el does. So when u-boot goes to read the FAT filesystem and load in the ke=
rnel, it fails.
One thing that might work (Although it may mess you up in terms of kernel m=
odules and such?) is setting up u-boot to load the kernel from flash (which=
you use with your openembedded openmoko distribution) and then pointing th=
e kernel command line toward your SDHC Debian root partition.
To do this, you will have to boot up u-boot with the prompt. Press and hol=
d the power button, and THEN (after, not before) press and hold the AUX but=
ton.. and hold them until you see the the boot prompt. Then connect a USB =
cable, and if your PC has the right drivers, you should have access to a se=
rial port, such as /dev/ttyACM0 which you can connect to, in order to get a=
u-boot command line.
These commands should get you started:
printenv
setenv
saveenv
Notice the menu_# variables. You'll want to make a hybrid which boots exac=
tly the same as internal flash (taking the kernel from flash) except that t=
he root=3Dxyz paramater will be different.
I suggest that someone make up a wiki article explaining how to do this whi=
le they're figuring it out. (I've already had to do it once myself)
