I followed the instructions here to install a SD converter with a microSD card and can not get it to mount.  I compiled my own driver (changing the hex address from the one for GPIO5 to the one for GPIO2.

Relevant dmesg stuffs from after an insmod mmc:

mmc Hardware init
mmc Card init
mmc Card init *1*
mmc Card init *2*
Size = 1985024, hardsectsize = 1024, sectors = 1985024

devfs_mk_dir(mmc/disc0): using old entry in dir: 809e1e60 "mmc"
devfs_register(disc): could not append to parent, err: -17

dmesg after 'mount /mmc':

Any help would be great.

edit: I thought it might be my soldering but I went back and did a continuity check with a multimeter as well as cleaning up the solder job but no go.

edit2: Also, if I try to mkfs.ext2 /dev/mmc/disc0/part1 the router stops functioning until I do a hard reset.  I formated the media as ext2 on my desktop now so it should be mountable.

edit3: Here's some more information from another similar thread.

I just did the mmc mod on a wrt54gl v1.1 myself and made an ipk for it.  I'm having problems formating (freezes a short way through and I lose my network connection) and it won't mount but that might be a hardware problem.  You might try it though...

edit: I forgot to put the source up... one second. Here it is.  Only change is the address for SD_DI from whatever the original was to 0x04, a line of comments above, and some comments on each line.  I wasn't sure if it was the code was the same as that here so I made the changes in the source for the mmc.c that 7.09's build system downloads.
