Hello list members, here another FR success story: Booting and usage of a large 16GB SDHC works!
My configuration and recipe: - QtExtend on flash - Debian on microSD (ext2+ext2) [1] - u-boot daily (8 Nov 2008) from [2] - Applied configure-uboot.sh from [3] - Kernel for Debian from [4] (but the kernel should not matter) - microSD card: Vendor: SanDisk Model: SDSDQ-016G-E11M Size: 16GB Speed: Class2 With this configuration I encountered first this error (output from minicom, /dev/ttyACM0) when I tried to boot directly (i.e. just pressed "power" on the FR): --- 8< --- snip --- Card Type: SD 2.0 SDHC Manufacturer: 0x03, OEM "SD" Product name: "SU16G", revision 8.0 Serial number: 2684394330 Manufacturing date: 8/2008 MMC/SD size: 3MiB cmd 0x10, arg 0x200 flags 0x15 Error after cmd: 0xfffffffc cmd 0x11, arg 0x0 flags 0x235 Error after cmd: 0xfffffffc bad MBR sector signature 0x0000 ** Bad partition 1 ** Wrong Image Format for bootm command ERROR: can't get kernel image! --- 8< --- snap --- Note that mmcinit reports a false size [5]. Booting manually from that point worked well: --- 8< --- snip --- GTA02v6 # boot Card Type: SD 2.0 SDHC Manufacturer: 0x03, OEM "SD" Product name: "SU16G", revision 8.0 Serial number: 2684394330 Manufacturing date: 8/2008 MMC/SD size: 3MiB 1939024 bytes read ## Booting kernel from Legacy Image at 32000000 ...

Tested. Works. :-D Note: There is still an issue with the suspend mode [6]. But my MBR was not eaten (until now ;-) ). I was able to fix a mangled filesystem on the card with a fsck.ext2 -y /dev/mmcblk0p2 after booting the Linux from flash. Enjoy!
