Hello,
I wrote a SPI Driver for Collie. It's very slow, because it runs at the lowest clock ATM. You can play with different speed using: /sys/bus/locomo-bus/drivers/locomo-spi/clockmult /sys/bus/locomo-bus/drivers/locomo-spi/clockbase I don't know yet what the numbers mean, but I will soon. Patches can be found at http://www2.informatik.hu-berlin.de/~tkunze/zaurus/patches . The important ones are: locomo-r0.patch: -fixes GPIO direction setting -implements SPI irq setting locomo_spi-r0.patch -the spi driver mmc_spi-r1.patch -from LKML with very little changes by me I will provide a bootstrap-image for testing soon: http://www2.informatik.hu-berlin.de/~tkunze/zaurus/images Cheers, Thomas |

My Collie send's you a kiss
 Is kexec patch working? Better i test it. Thanks!! -edit- Module locomo-spi loads ok but device does not auto-mount (1Gb SD) I can't find the /dev/xxx file to mount it. ¿Should it be easy? #modprobe locomo-spi - Modules loaded: mmc_spi mmc_core locomo_spi Messages: no card power management can't initialize the card: no card? I wana test to load diferent kernels with filesystems with kexec (2.6 kernel) using your image as "grub"

Some cards doesn't work yet. I will get some new test cards soon. The patch is in OE now, so you can recompile the modules with debugging support. If you do "echo "1" > /sys/bus/locomo-bus/drivers/locomo-spi/verbose" you get additional debug messages.

AFAIK there is no status page for 2.6 on collie. Maybe I should set up one. You can find some pieces of information with google, but much is out of date. There are angstrom-test images at: http://www.angstrom-distribution.org/unstable/images/collie/
The kernel is not ready for end-users yet: Things that work more or less: - LCD - Keys - Leds - PCMCIA - MMC/SD - Serial Port - Flash - Battery/Charging Things that should work (havent tested): - Touchscreen - Irda - USB Client Things that doen't work yet: - Suspend/Resume - Audio (buzzer + headphone jack) The SD driver should support at least 4 GB SD-Cards. You have to load the modules locomo-spi and mmc-block to use SD-Cards. |
