Here is what I did to program 1 GB sdCard. Can't do bigger than 1 GB because the block size is no longer 512 and the dd file supplied by technologic uses 512 byte blocks. Need to have Technologic provide dd image using 2048 byte blocks for 4 gb sd card.
---------------- Instructions for creating 1GB SDCard. 1 GB is the biggest size that works with 512 byte blocks in
Creating SDCard for 7400 using 7400 sdcard slot and nfs mount Fownload latest SD card image link from
unzip it to get sdimage.dd put sdimage.dd in directory on nfs server
insert new 1 GB sd card into 7400 sdcard slot
boot 7400 into fastboot mount nfs directory where sdimage.dd can be reached
load sdcard devices $ insmod /sdcard.o dmaenable=1 Now the sdcard shows up in devices as /dev/sdcard0/disc0
Copy sdimage from nfs server onto sdcard
$ dd if=/mnt/root/home/sdimage.dd of=/dev/sdcard0/disc0/disc 487936+0 records in 487936+0 records out
Now use fdisk in interactive mode to get partition sizes $ fdisk /dev/sdcard0/disc0/disc
The number of cylinders for this disk is set to 3888. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): Command (m for help): p
Disk /dev/sdcard0/disc0/disc: 1019 MB, 1019215872 bytes 16 heads, 32 sectors/track, 3888 cylinders Units = cylinders of 512 * 512 = 262144 bytes

Now to resize partition 3 we have to delete it and then make a new one of the bigger size
Command (m for help): d Partition number (1-4): 3
Now create a new one starting at the same cylinder but ending at the last cylinder 3888
Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 3 First cylinder (11-3888, default 11): 20 Last cylinder or +size or +sizeM or +sizeK (20-3888, default 3888): 3888
Now check partition table
Command (m for help): p
Disk /dev/sdcard0/disc0/disc: 1019 MB, 1019215872 bytes 16 heads, 32 sectors/track, 3888 cylinders Units = cylinders of 512 * 512 = 262144 bytes
Device Boot Start End Blocks Id System /dev/sdcard0/disc0/part1 1 6 1520 da Unknown /dev/sdcard0/disc0/part2 7 10 1024 da Unknown /dev/sdcard0/disc0/part3 20 3888 990464 83 Linux
Now write out new partition table
Command (m for help): w The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 22: Invalid argument. The kernel still uses the old table. The new table will be used at the next reboot. Syncing disks.
fdisk will quit
Now reboot to use new partition table and check it using fdisk
$ reboot $ insmod /sdcard.o dmaenable=1 $ fdisk /dev/sdcard0/disc0/disc
Quit fdisk Command (m for help): q
Now run e2fsck to repair file system before resizing $ e2fsck -f /dev/sdcard0/disc0/part3 e2fsck 1.37 (21-Mar-2005) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/sdcard0/disc0/part3: 15068/60000 files (0.5% non-contiguous), 218714/239104 blocks
Now resize the partition. Need access to resize2fs executable. Used one on nfs mount. the ext2resize not provided
$ /mnt/root/sbin/resize2fs -f /dev/sdcard0/disc0/part3 resize2fs 1.37 (21-Mar-2005) Resizing the filesystem on /dev/sdcard0/disc0/part3 to 990464 (1k) blocks. The filesystem on /dev/sdcard0/disc0/part3 is now 990464 blocks long.
Now install the 7400 kernel from nfs mount. Get kernel here
$ dd if=/mnt/root/home/ts11-ts7400-1.01.dd of=/dev/sdcard0/disc0/part1 2838+1 records in 2838+1 records out
Now copy over the 7400 modules from nfs mount Get modules here
Need to mount sdcard first $ mkdir /mnt/sdroot $ mount /dev/sdcard0/disc0/part3 /mnt/sdroot
$ tar -xzvpf /mnt/root/home/modules/tskernelmodules-2.4.26-ts11-7400.tar.gz -C mnt/sdroot/lib/modules
Check file system usage $ df Filesystem 1k-blocks Used Available Use% Mounted on /dev/root 1003 947 56 94% / 10.0.2.140:/volumes/aux/data/nfs/sarge112155782288 114489552 41292736 73% /mnt /root /dev/sdcard0/disc0/part3 959921 211198 709105 23% /mnt/sdroot
Update preboot only if you want to always boot to sdcard. Since I want the flexibility of booting to fastboot, I , don't do this step. Has nothing to do with creating SDCard anyway.

All SD-cards prepared according to
http://www.embeddedarm.com/epc/fastboot.htm
with an SD-card reader suitable for 4G SD-cards.
Any clues out there?
First problem, not so important:
We can't get it to boot at all.

Second problem, with 512M and 1G SD-cards, rather important:
For some reason we are not able to bypass the fastboot on the TS-7400.
With the original SD-card we had no problem.
