Re: Collie MMC SPI Driver alpha2

Hi,

I inserted the LinkSys Compact Flash card, and it was immediately
recognized!

I tested 1GB SD (Sandisk):

On insert, it was automatically mounted.
There were following messages in dmesg:

<7>Collie MMC over SPI Driver
<6>mmc_spi .0: SD/MMC <-> SPI proxy driver, no card power management
<4>mmc0: Problem switching card into high-speed mode!
<6>mmcblk0: mmc0:0000 SD01G 992000KiB
<6> mmcblk0: unknown partition table
<4>EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended

I was able to see files on it. md5sum of /dev/mmcblk0 returned same result
twice.
Data reading speed was about 735 kb/s (readed 1GB in 1381 seconds).

Write was faster, at about 1028kb/s. I used following commands to test write
speed:

date; dd if=/dev/zero of=writetest bs=1024k count=100; sync; date

Then, I tested 16MB Panasonic SD. md5sum produced same results for 3 runs.
Read speed was the same as with 1GB card.

I don't know whether following issues are user-space or kernel-space:

   - Battery LED remains off on power connect. Apparently, the battery is
   actually charged, as the thing is working for an hour already with WiFI on.
   - USB-net interface is not activated. May be I miss a kernel module?
   - Keyboard mapping of "OK" button is not "ENTER".
   - When I press "Cancel" button, I get following error:
"power.cdevice-level power management is not supported yet.". Do you
plan to work on
   it?
   - State of "battery compartment switch" is disregarded, as the device
   starts booting immediately as I press "RESET" button.
   - frame-buffers is turned off completely after several minutes of
   inactivity on the console. IMHO, unless configured, the default behavior
   should be just to turn off highlighting.
   - Apparently, /dev/sharp_buz is not implemented yet. I tried to check
   it using attached "buzzme" (taken from kismet) program.
   - command "halt" did not led power down, but rather to some suspended
   state, with garbage on FB (with console output remnants). After I closed the
   keyboard compartment, the system started regular booting.

I remember, that from-factory Sharp Zaurus distro was able to utilize
built-in speaker, to playback music. Will it be possible with the kernel 2.6?
Why was the peripheral abandoned in OpenZaurus?
