Len,
I am using the 7800 card and have successfully "stretched" the 7800 512 MByte
image the Technologic onto a 4 GByte SD card. Here are the steps I took:
1) dd if=/home/ts7800/512-meg-image.dd of=/dev/mmblk0
- the 512-meg-image.dd is from the Technologic guys
- the /dev/mmblk0 is the SD card device on my laptop
2) eject the SD card from my laptop
3) re-insert the SD card into my laptop (forcing a mount and cleaning up the
partitions)
4) Use GParted to stretch the 500 Meg partition to consume the rest of the SD
Card.
5) eject the SD card from my laptop
6) re-insert the SD card into my laptop and alter any files needed.
I'm guessing there are easier ways. However, I was a little disappointed that
the partitions spelled out did not end on cylinder boundaries, which makes it
much harder to use fdisk...
