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? -- Kristoffer Nyborg Gregertsen MSc. student / Summer intern Atmel Norway - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
