Howdy All, I have (almost) successfully upgraded from Linux 2.6.22 to 2.6.26 (both downloaded from debian) on my mpc8347 powerpc, but I think I may be missing a required change to my dts regarding the IPIC or maybe a change in how my driver requests IRQs. I have several modules that are

Compact flash on mpc8349eITX

2008-08-01 Thread Sparks, Sam
I'm trying to get the compact flash up and running on an mpc8349eITX, and am continually running into issues where the IRQ is not processed, and the mmio commands are not getting response. At this point, I am starting to suspect a HW issue, but I was hoping to verify that I am using a known good

From: Sparks, Sam Sent: Thursday, July 31, 2008 8:15 AM Does irq polling need to be used for compact flash to work with this version of the kernel on this board? When I remove the interrupt definition from the DTS (to cause irqpolling), the ata driver gets stuck in a loop displaying

Which repository on kernel.org should I use to pick up the latest-greatest software for the mpc8349mITX? I've tried linux/kernel/git/vitb/linux-2.6-8xx.git, but the dts doesn't contain compact flash nodes. I've tried linux/kernel/git/paulus/powerpc.git, but the kernel hangs while trying to
