Collie and SD/MMC support under 2.6 kernel

Few days ago Thomas Kunze wrote to openzaurus-devel list that he has working SD/MMC driver for Sharp Zaurus SL-5000/5500 (aka Collie). He provided patches and later also Ångström image + kernel so anyone can test.

I asked him for patches to current OpenEmbedded metadata and added them later so now anyone can build 2.6.20 kernel for collie to test SD/MMC. Koen Kooi built images for Ångström so it can be taken as start of support for this machine. Who knows.. maybe there will be no new OpenZaurus release when driver will work OK…

My collie (after charging and removing dust) booted nicely to 2.6.20 powered Ångström console image so I was able to test my cards against driver. Only 16MB MMC card was working so I sent two SD cards (64M and 256M) to Thomas. Now he will have also some not-yet-working cards for testing (all his SD/MMC cards works).

Also worth reminding — there is a bounty for writing SD/MMC driver for collie/2.6 so if you want to appreciate Thomas work you can join 😉

  1. I tested the Koen’s image and initrd, and found several problems. Is there bugs tracking system, that I can file them into?

  2. Kernel 2.6 for collie is not complete yet. So theres no point filing kernel related bugs.

  3. Skliarouk Arieh: you can report bugs in OE bugtracker ofcourse but I think that you should post them to OZ devel ML first. There you will get response with information what is done or not.

  4. I’d like to test the images, but I’m not sure how to use them. If I have OZ 3.5.4 flashed, can I use the images with altboot? What is the modules tarball for, is it required?

    very exciting, thanks Thomas! I replaced the long-broken digitizer on my 5500 late last year, but I haven’t been able to get a recent OZ going since (mount segfaults whenever I try to mount an SD card).

    Do touchscreen, USB client, sound, and suspend/resume work with 2.6 on collie? http://www.cs.wisc.edu/~lenz/zaurus/ indicates that they don’t but it’s ~2 years old.
