Excellent! Thank you for letting me know. I’m sure it will be useful when I look for replacements.

Hello Phillip:

That’s a great solution to finding the GPIO pins, I think I had to do that once or twice when I wrote the article. I didn’t think to put it in there, but kudos on figuring out the fix!

You might need to give it a few minutes, depending on the size of your SD card and whether or not the card was formatted ext3 when you put it in. One thing I noticed was that the card was instantly reformatted upon insertion as it was originally formatted FAT32. And, I’m sure you’ve checked it but check once more and make sure that the Write Protect switch is unset. (I had this happen to me too on an unrelated project, set me back for a day. )

If you are still unable to write, use your oneliner script to check your other GPIO pins per the article. Unfortunately, I’ve sold my unit since the article was written so I’m not sure I can assist much further than the information in the article. I’ll try to help as much as possible, but can’t guarantee anything.

Good Luck!

I have found gpio 5 for my board rev:XH just underneath where this tutorial said.

i tested it with

while true;do gpio enable 5;sleep 1;gpio disable 5;sleep 1; done

then tested the pins with a multimeter

So now i know they are all where i expect them to be.

however i still cant create anyfiles in the /mmc dir

THANKS for putting this up, I just ran out of storage, man I hear that some of these have 32mb of ram and only 16 is enabled by default requiring a softmod to enable the other 16m, but I see 32mb in the www interface, so not sure how true that is.

Please keep this up as I plan to do this very soon as I get the parts, thanks!
