Is it possible to use the IDE-Interface in UDMA2 mode with the TQM5200?
We have a Debian Lenny running on a TQM5200 on a STK52xx with a
Denx-Linux-Kernel 2.6.33 in the Denx default configuration (make
52xx/tqm5200_defconfig). We can do hdparm -I or hdparm -i (output see below)
However, all hdparm commands like
hdparm -d /dev/sda
fail with
/dev/sda:
HDIO_GET_DMA failed: Inappropriate ioctl for device
In general, it is impossible to set anything, there is always the error
"Inappropriate ioctl for device".
Is this a kernel config issue, or a mismatch Denx-Kernel /
Debian-hdparm, or is it just not possible with the TQM5200?
Thank you for any comments,
Marc Scherer
