Tested with an Freerunner (GTA02v6). Other software setups may work too. Important in any case is to have a recent u-boot in your NAND.



  • QtExtend 4.4.2 on flash, Debian on microSD
  • Kernel 2.6.24 from here
  • The card was formatted with ext2 filesystems during Debian installation:
root@om-gta02:~# fdisk -l /dev/mmcblk0

Disk /dev/mmcblk0: 15.9 GB, 15931539456 bytes
4 heads, 16 sectors/track, 486192 cylinders
Units = cylinders of 64 * 512 = 32768 bytes

Device Boot              Start         End      Blocks  Id System
/dev/mmcblk0p1               1         245        7832  83 Linux
/dev/mmcblk0p2             246      486192    15550304  83 Linux
  • Most important: Add extra settle time for sd card, see posting (section references) for a how to.

Pending Issues

  • mmcinit reports false card size 1815. But works fine once booted.
  • Suspend may mangle your filesystem. Workaround: Disable suspend or, once mangled: Boot from flash and then issue:
fsck.ext2 -y /dev/mmcblk0p2
  • Running halt after booted from sd card may mangle your filesystem too. Workaround: add extra sync:
sync; halt

Linux 2.6.32

On 2.6.32 kernel card doesn't work.

  • Add kernel parameter glamo_mci.sd_max_clk=2500000 as workaround.
