I think I came up with a better solution for the problem of how to |
quickly transfer a disk image to the FPGA board (several hundred |
megabytes): instead of transferring the data over the serial line, |
we write the disk image created on the development system onto |
a hard disk (or SSD), and then swap drives. This can easily be |
done utilizing an USB-to-IDE converter (e.g., from an old external |
hard disk drive enclosure). The disk image is simply written to |
the disk using the "dd" command, with the whole USB mass storage |
device (e.g., /dev/sdb) as the destination. |

Another error in the IDE disk interface showed up yesterday: |
the two bytes of every halfword are byte-swapped on the storage |
medium! This error can only be discovered if the disk is written |
with a non-ECO32 controller and read with the ECO32 controller, |
or vice versa, which is the reason for the error hiding for so |
long. |
