Re: HDD on Etrax100LX IDE developer board
The kernel version is 2.4.14 with the patch on the axis web site.
I now suspect the hardware.
According to the schemetic of the IDE developer board.
There are some differences from the old IDE developer board.
New hardware has buffers on ATA_DIOW0, ATA_DIOR0, ATA_DMACK0.
I'm changing the hardware.
