hi all,

i'm new to this forum and to openwrt; so please forgive me any newbie-mistakes...

i have a linksys wrt54G Rev 3.1 with SD-mod, running kamikaze 8.09 (kernel 2.4.x)... the sd-card is working...

now, i wanted to mount the sd-card to have enough space to install some additional software - to do this, i followed this howto (i like the idea to have the original filesystem still "available" if anything fails):
http://oldwiki.openwrt.org/OpenWrtDocs( … HowTo.html

after setting the correct gpiomask for the rev 3.1-mod, everything works fine, EXCEPT:
- the part "Testing the script with your setup"; grep-commands make the router stall
- autostarting the bootext-script will cause a loop, which can only be stopped by removing the micro-SD (i soldered the sd-adapter on the linksys, so i can change the microSD) and power off/power on the router...
- starting the script (/etc/init.d/bootext start) will also make the router stall

B U T    when (the rooter boots "normal", and) i enter the command

echo "0xb8" >> /proc/diag/gpiomask

manualy before "bootext start", everything is working fine...

i copied the bootext-script and the bootfromexternalmedia-config 1by1 from the howto-page, altering the gpiomask and mount-points i needed...  as a "new to linux-script and -config"-guy, i think the echo-command in the bootext-script is not beeing processed/or not in the needed chronological order... at the moment, i start the router without bootext, then i enter the gpiomask & start the bootext-script... due to my "experiments" with/on the router & the software, i have to reboot frequently, what makes this procedure very ... hard.

does anyone has an idea how i can solve this problem, so i can enable the script for automatic start on bootup?
(if you need any config-files or system-logs: pls. tell me which ones, or how i can get them & i'll post them, thanks!!)

cheers & thanks for any reply!

Hello,
Sorry that's not an answer rather a question.

I have the same configuration(Kam 8.09.1 vs 2.4), trying to do the same work, execpt i use an WRT54GL V1.1 so my gpiomask is 0x9c.

My SD card works very fine through ext3 ... after format in my external linux box and some capacitors (100nF + 10µF in //) very near (on!) the SD adaptator for the microSD.

But when i try to follow the topic  testing /ect/init.d/bootext stop fail:
-ash : can't find /etc/rc.common

Of course the /etc/rc.common is well here and reacheable.
Of course when trying to boot, i run in a dead lock  ... "attempt to kill init" and reboot!

Every script with #!/bin/sh /something ... ash can't find the something.

I'm running crazy!
I'm shure that it must be so simple to fix!

Have you some light for me ... may be only a candle!

By advance thanks, and sorry about my froggy english...

I had the same problem as mike-k. I inserted the line

echo "0x9c" >/proc/diag/gpiomask

at the beginning of function 'bootext_start()' and commented out following line:

#[ $module != mmc ] || [ ! "$gpiomask" ] || echo "$gpiomask" > /proc/diag/gpiomask || bootext_fail "could not set gpiomask"

After that I could enable the script like described in:  http://oldwiki.openwrt.org/OpenWrtDocs% … HowTo.html
Now after booting OpenWRT my mmc-card was correctly mounted as root directory.

After that opkg still tried to use the old filesystem instead of the mmc card. Now i edited /etc/opkg.conf and commented out following line:

#option overlay_root /jffs

And finally I could install packages on the mmc-card.
Hope this helpes anyone
