Hi again everybody,
The driver is now working very nicely. The sporadic errors I reported earlier
were mostly due to the state of the EBI to ATA adaptor prototype card.
I have also added some time before R/W strobe to make sure signals are stable.
The only thing that bothers me is the huge number of interrupts that occurs
during data transfers. There is one interrupt for every ~500 bytes or so:
-sh-3.2# cat /proc/interrupts
...
65: 62015176 eic at32_ide
-sh-3.2# dd if=/dev/zero of=zero.dat count=10k
10240+0 records in
10240+0 records out
-sh-3.2# cat /proc/interrupts
...
65: 62025176 eic at32_ide
Would I be better off using polling mode?
