If this works, you safed my bachelor thesis!Thanks!!! I am using 2 x 10uF ceramic 0805 smd in parallel with my sdcard adapter (must be soldered very close to the sdcard pins).p. That's why I suspect MISO. Using the CardInfo example of the SD library I even can initialize the Card properly.But there can't be found any partition on the card and I really can't tell why.
long wires (shall be <15cm)p. I think the right signals reach the card, but the answer doesn't find it's way to the arduino.I can post some osci-screenshots if you guys think it might help.Maybe important: I fat16lib Edison Member Posts: 2,180 Karma: 247[add] Arduino rocks Re: Micro-SD Card not formatted #1 Jul 28, 2012, 09:24 pm Most likely it is not a format problem. This holds MISO high when there is no card and insures there won't be a false acceptance of CMD0, the first initialization command.
Same error code and so on...I'll try to connect the Miso directly to the Arduino and post the results. The best results are with smd ceramic multilayer capacitors ie. 10u, 22u, etc. Guess it works since the Max low input is 0.3Vcc.Edit: I checked some posting on AVR Freaks and the claim is:QuoteThe AVR clearly has much better specification, as at 5V vilmax It would be helpful if you ran two example from the SdFat library.
missing SDcard's signals pull-up resistors - I always use ~10kohm on DO, DI, CS4. It appears to nearly work. I'm new to this so just confirming: About 10k in series on the 3.3V side of my levelshifter(so between shifter an SD-card). Sd Card Initialization Commands missing decoupling capacitor close to the sdcard (min 10uF ceramic, between vcc and gnd)3.
But my Arduino gives the clock, so I don't think so :-)2. Sd Card Spi Initialization Sequence This may give a better indication of where the problem is.It would be great if there was a way to connect MISO directly without the level shifter.

SdFat is located here http://code.google.com/p/sdfatlib/downloads/list.Run the SdInfo and QuickStart examples and post the error messages with error codes.If you get a message like this with an errorCode, you have a basic I'll definitly try this one!!3. Sd Card Spi Protocol Other utilities do not comply with the standard and won't help solve your problem.Most likely you have a low level I/O problems. Sd Card Spi Interface Code I'm using a SanDisk 2GB and the Mega-Board.Thing I already tried: - make it smaller than 1GB by partitioning
Success for this command is a status of 0X01 which can easily happen with noise and no CRC. 0XFF is busy so if MISO is held high, commands fails with a pito Edison Member Posts: 2,228 Karma: 115[add] Pukao hats cleaning services Re: Micro-SD Card not formatted #3 Jul 29, 2012, 02:00 pm Last Edit: Jul 29, 2012, 02:56 pm by pitoReason: Maybe there's a loose contact or something and I couldn't get the rest of the message... fat16lib Edison Member Posts: 2,180 Karma: 247[add] Arduino rocks Re: Micro-SD Card not formatted #8 Jul 29, 2012, 04:17 pm Last Edit: Jul 29, 2012, 04:27 pm by fat16libReason: 1 It's Micro Sd Card Spi Interface

For read CID the status 0X1F, would be:Quote• In idle state: The card is in idle state and running the initializing process.• Erase reset: An erase sequence was cleared before executing typical issues when running an sdcard:1.

This works even though a high level of 3.3V seem marginal as an input to the ATmega.
