Wav shield card init.failed

by sfta on Fri Aug 15, 2008 1:11 pm

After getting this error, I read all other posts on this topic, and was wondering if there is a reliable way to get things working. There are a few different approaches offered in the forum:

Check all the joints on the board
Formatting the card on a mac, then reformat on a pc
Update the library
Try a card thats under 1gb or until you find one that works

I've tried the first three and would like to avoid the last option. The trick seems to be in the formating. Can someone post how the managed to do it?

the details:

sd card: Panasonic 1gb class2
Arduino NG 168
wave with the NG hacks

Not sure if its SDHC but def class2.

What type of cards will work? Is there documentation that I missed.

Dang. That might explain my troubles...

'standard issue' SD cards work fine. i now stock standard SD 1gig cards in the shop since people seem to have trouble finding them

I found a problem with my board, the C5 cap was in the wrong place. I removed and replaced it, but it didn't solve the card failure. Did I fry a chip?

Anyway, here is a photo:

Thanks for the help.

the kit hasnt been tested very well with an NG...id try a diecimila arduino (they're the current rev) after you replace the changed components

There have been rumors off on the JuiceBox forum (an ARM based video player that runs linux) that not all "SD" flash cards support the SPI/MMC mode that most simple devices like to use. IIRC, Kingston was one of the vendors that was supposed to be problematic... ( JuiceBox BBS post )

So before you get too paranoid about possible mistakes, you might want to try a different flash card.

(I don't think anyone ever explained WHY the kingston cards had problems; they're normally a pretty reputable memory vendor...)

Got my hands on a Diecimila, and shield is now working fine (after unhacking the NG hacks). So... upgrading an NG to an ATmega168 ain't enough--get a Diecimila and avoid some pain. The SD cards don't seem to be a problem after all.

SD cards that I have working:
Kingston 1GB
Dane-Elec 1GB
Panasonic Class 2 1GB

All were formatted on a PC running XP pro with a SanDisk ImageMate 5 in 1 reader.

Thanks to all who offered help and encouragement.
