I've heard on-and-off that there are problems with the CF support on the 8349 ITX, but I've never had the chance to investigate it. Can you try using the latest BSP kernel and see if the problem is present there? Sometimes the BSP has a hacked-up kernel that addresses hardware issues, but these patches aren't pushed upstream, so the mainline kernel has problems. -- Timur Tabi Linux kernel developer at Freescale ^ permalink raw reply [flat|nested] 14+ messages in thread

Looking at logs Sam Sparks provided (without irq): ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) it seems data transfer failed. I have a 8 bit data transfer mode dirty hack on pata_platform.

Well, w/o IRQs everything is OK. I think it's just a bogus message after the interrupt issues.

The CF card seems to work fine. See if your kernel supports vfat by # cat /proc/filesystems Of course, you need to mount /proc properly first. If your kernel doesn't support vfat, make it support. Or you can insert a blank CF card and play with it (ext2, etc) ^ permalink raw reply [flat|nested] 14+ messages in thread

I purposed two patches to Jeff: one is + ioread8(ap->ioaddr.status_addr); I.e. clear an interrupt before requesting (just to be sure, I guess libata is doing this already, just don't see where exactly). That didn't work. :-/ And another approach was to try IRQ-less pata (another patch). -- Anton Vorontsov email: cbouatmailru@gmail.com irc://irc.freenode.net/bd2 ^ permalink raw reply [flat|nested] 14+ messages in thread

Hello All,
I'm using the latest 2.2.26 kernel image from
linux/kernel/git/benh/powerpc.git on a mpc8349mITX, and trying to get
Compact Flash to work. The kernel booted fine, but I was surprised to
see Compact Flash IRQ was not being handled. Does irq polling need to be
used for compact flash to work with this version of the kernel on this
board?
Here's snip of the unhandled IRQ, for your edification.
irq 23: nobody cared (try booting with the "irqpoll" option)
