Booting
Booting the gumstix from a micro SD card
Currently, I boot the gumstix from a 2GB micro SD card. NOTE that 4GB SDHC does work to boot from. If booting from flash, the card is found and read/write works fine even with 4GB. Probably the U-boot version does not support SDHC cards. These instructions for setting up the MicroSD card works fine for me. Don't forget to enable the MMC_ROOT by uncommenting the line in the ~/gumstix/gumstix-oe/com.gumstix.collection/conf/machine/gumstix-custom-verdex.conf
MACHINE_FEATURES += "mmcroot"
If boot hangs at ??
The first boot from the SD starts fine, but hangs after a while at This seems to be a problem with ... and can be worked around by interrupting the boot by pressing 'Ctrl-c' on the serial console, which lets the boot continue. Then you can log in. At this point removing "status" and "status.tmp" from /usr/lib/ipkg/ , should make the boot process complete at the next boot. Here's the post that I found and worked for me link
