Hi Jordi,
I have this nagging suspicion that I'm missing something fairly
fundamental.
In the instructions in the Users guide, the SD card is partitioned
with only _1_ partition, using the whole card. But if I inspect the
512M card from Technologic it has 3 partitions.
fdisk reports that the first 2 are quite small (type da) and the third
contains the rest. Equally the Technologic card does not have any
partition set as "bootable" where-as the instructions do say to make
the partition bootable.
I know this is probably laughably basic to y'all, but consider this a
plea from a rapidly-balding-programmer...
Cheers
Bruce
