Hello,

Could anyone explain howto set the gpiomask? It would be nice to have something about this at the wiki in a bit more detail. I have done the SD/MMC mod on an WRT54GL with kamikaze 7.09 installed. It works fine but as soon as I mask out (every?) gpio line with my wlan led is constantly off. I use the router in client mode and the wlan interface is the wan interface so this led is the only indication if any data are transmitted to the outside world.

I have used "echo 0x9c > /proc/diag/gpiomask". I would like to be able to just mask out

gpio2 white led
gpio3 orange led
gpio4 cisco switch
gpio7 dmz led

which are the lines I have used for the mod. What is the right mask for that? Could anyone who knows about this in more detail produce a masking table? I have followed the excellent howto from http://home.versatel.nl/janssenmaj/mmc-sd-mod.html for the mod. Thanks for the nice tutorial and the good work!

Alexander

Hi,

Ok, I have found what I was looking for in another post at

http://forum.openwrt.org/viewtopic.php?id=8543

Here is a list with the GPIOs and its hex values:
GPIO PIN 0: 0x01
GPIO PIN 1: 0x02
GPIO PIN 2: 0x04
GPIO PIN 3: 0x08
GPIO PIN 4: 0x10
GPIO PIN 5: 0x20
GPIO PIN 6: 0x40
GPIO PIN 7: 0x80
GPIO PIN 8: 0x100
GPIO PIN 9: 0x200
GPIO PIN 10: 0x400
GPIO PIN 11: 0x800
GPIO PIN 12: 0x1000
GPIO PIN 13: 0x2000
GPIO PIN 14: 0x4000
GPIO PIN 15: 0x8000

If I add up the gpio lines I have used in the mod I get a hex value of 0x9c, so the mask command is alright. The led's can be fixed with

echo "1" >/proc/diag/led/power
echo "1" >/proc/diag/led/wlan
