Hello everyone.
I'm currently evaluating the possibilities and disadvatages of using linux in an
embedded pump controller. We are using the elan SC4x0 chip, and I have tried
both AMD's evaluation board (yes, I know, that specific board have been discussed
here for quite a while;) and the JumpTec DimmPC.
The problem with appropriate flash memory drivers for Linux that seem to have been
bothering some people
here was initially the main problem for me. Until I tried the DimmPC (and also the
sandisk
flash ChipSet). The DimmPC uses a sandisc 16 mb flash disk with the FCS system,
allowing the hardware
to completely emulate an IDE interface. This way, you get rid of not only the flash
driver problems
in Linux but also the whole boot process is simplified. (initial ramdisk etc goes down
the drain)
But when mounting the disk in Linux, I get the following:
hda: hda1
hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hda: drive_cmd: error=0x04 { DriveStatusError }
hda: hda1
but the drive is mounted alright and everything seems to work
when I unmount the drive and mount it again I only get
hda: hda1
hda: hda1
hda: hda1
My questions are:
* why the error stuff above? what does it mean?
* why is [hda: hda1] written to console. Normally when you mount a IDE drive I don't
get any messages. I believe that the sandisk chip completely emulates an IDE driver.
