Hi at all...

I have RC2 on my fonera, I install LuCI Components:
- luci-app-mmc_over_gpio

and in automatic install:
- kmod-mmc
- kmod-mmc-over-gpio
- kmod-mmc-spi

And now? For mount mmc? For insert a swap file?

Well, you have to backport the init script and config file for UCI from trunk to make use of luci-app-mmc_over_gpio in 8.09 RC2

And I can make this? How?

Sorry but I not understand...
... con you explain me how to do?

Thanks and best regards,
Elia Finotti

News...

in fstab I see this:

gpio-mmc: Failed to request mmc_spi module.
mmc_spi spi32766.0: SD/MMC host mmc0, no DMA, no WP, no poweroff
gpio-mmc: MMC-Card "default" attached to GPIO pins di=1, do=3, clk=4, cs=7
mmc_spi spi32766.0: can't change chip-select polarity
mmc0: new MMC card on SPI
mmcblk0: mmc0:0001 AF HMP 250880KiB
mmcblk0: p1

but if I mount mmcblk0 -> mount: mounting /dev/mmcblk0 on /home/sd failed: No such device

and now?

Argh... for me this problem not have a solution... not work... recognized but not mount...

hi,

in our device directory they are the "/dev/mmcblk0p1" and the "/dev/mmcblk0"

the mmcblk0 is the card device

the mmcblk0p1 is the first partition on the card device (this you may use not all de device card itself)

Try mount the  /dev/mmcblk0p1, if you have a error, this means that you do not have a partition on de card.

Create a partition and try again.
Many brand new cards not have partitions created or have bad created (my experience).

Hi Vasco,
thank you for your reply...
... I have a fat partition, with legend 4.5 firmware this sd work good.
I not understand...

mount /dev/mmcblk0p1 /home/sd

this is all you need to mount it

I have a Fonera 2100 router with Kamikaza 8.09.  I attached an 1 Gb microsd Kingmax card to it. In Kamikaze 7.07 the phrozen mmc driver works great (http://phrozen.org/fonera.html), but in 8.09 the built in mmc driver dont work.
I tried the luci-app-mmc_over_gpio with my real pins (1 3 4 7 0) config, but it dont worked.
But if i try it with 1 3 4 14 0 after stop and start with 1 3 4 7 0 it working and I can see that:

configfs on /config type configfs (rw)
gpio-mmc: Failed to request mmc_spi module.

root@OpenWrt:/# mmc0: new SD card on SPI
mmcblk0: mmc0:0000 SD01G 1006080KiB
mmcblk0: p1

what cause it? Do you have a solution for it?

Almost the same here. Tried different cards. SDHC, MMC and SD cards with different sizes. Could not get MMC/SD working with 8.09 final.

Sd in my 2100 with 8.09 not work... the same sd with Legend 4.5 firmware work correctly...

i got it working, it works just fine if you remove the filter caps on the board (on the top side next to SW1, there are 4 of them) i was having the same issue, if you set the config to 1 3 4 7 0 for the GPIO addresses, i have yet to test its stability, but i finally got the service to start

it took a second, but after failing, it gave me this and checking in /dev i have them listed and in luci, under "DEVICE" on the add a mount point, it says that /dev/mmcblk0p1 has a size of 241mb (i have a 256mb card in the card slot)

i'll post an update if i get it to mount

Update 1: i know its reading it properly, because it gives me

mmcblk0: mmc0:0000 SU256 247040KiB

for my 256
and

mmcblk0: mmc0:0000 SU04G 3872256KiB

when i put my phones 4gig card in

yeah i cant seem to figure out what i did wrong, i give up until i have some more time to mess around
