Mmc Soldered. Driver Almost Working Options

[guylhem]

Hello

Just to let you know the MMC has been soldered into the simpad, and the driver is being developped. Currently some basic tests (like powering on and off leds from a kernel module) work fine.

Attention - the picture on my website has the MMC card drawn backwards. it should read "Top view" instead of "bottom view".

I'll fix the picture.

fredyd, it's not stable enough - it needs power management support (if you suspend with a mounted partition, there's corruption...) will do that sometime

sash, did you succeed in having both the hard disk part and wifi part at the same time? I could under wince, I can't on linux. IIRC it's due to not applying some voltage, ie a driver problem.

@Guylhem: You were right - it's a driver problem.
I think first it was the actual pcmcia-cs package which does not support binding two
modules/driver to the same slot. And second nobody definitivly knows which initialising
command(s) are used to tell the connect+ to run in wifi+storage mode

Thus I soldered the sc-card to extend the memory.


Can you help me a little bit further to compile the module for an actual kernel?

I tried the following with the kernel from oe-tree:
1. modified the kernel-patch to enable mmc support (CONFIG_MMC=y)
2. replaced the linux/drivers/mmc/mmc_core.c with your mmc driver

If I compile the kernel using bitbake, a mmcdrivers.o and mmc_core.o is generated.
But both of them produce no output when I load them. insmod reports something from tainted kernel module.
IIRC it is only a warning and the module should function anyhow!?
lsmod reports that the module is loaded, but there is no dev/mmc directory.

Any ideas?


btw: The power management support could be released by the apm scripts.
I did the same with wpa_supplicant on my laptop: Unloading for suspend and reloading on wakeup.
