help
This provides a driver for the on-board flash of the Technologic
System's TS-5500 board. The flash is split into 3 partitions
which are accessed as separate MTD devices.
mtd0 and mtd2 are the two BIOS drives. Unfortunately the BIOS
uses a proprietary flash translation layer from General Software,
which is not supported (the drives cannot be mounted). You can
create your own file system (jffs for example), but the BIOS
won't be able to boot from it.
mtd1 allows you to reprogram your BIOS. BE VERY CAREFUL.
Note that jumper 3 ("Write Enable Drive A") must be set
otherwise detection won't succeeed.
