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 To complete the subscription, please click the link in the email we just sent you. 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 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 http://www.microchip.com/forums/m530149.aspx

I was dealing with this problem for 3 days straight.If you guys are ever near to Munich, give me a call :-)Thread closed. Well I think i should cut my testboard wires a little :-)First thing in the morning I'll try. This can happen due to noise on MISO since I do thousands of retries waiting for the card to go ready.

missing decoupling capacitor close to the sdcard (min 10uF ceramic, between vcc and gnd)3.

Sd Card Spi Initialization Sequence
It would be helpful if you ran two example from the SdFat library. typical issues when running an sdcard:1. Sd Card Spi Protocol fat16lib Edison Member Posts: 2,180 Karma: 247[add] Arduino rocks Re: Micro-SD Card not formatted #10 Jul 29, 2012, 05:26 pm The SD status, errorData, has too many one bits to make Sd Card Spi Interface Code long wires (shall be <15cm)p.
I guess this is why commercial shields work well. But my Arduino gives the clock, so I don't think so :-)2. It appears to nearly work. 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. Micro Sd Card Spi Interface
CS is the ChipSelect, Ok. I'm using a SanDisk 2GB and the Mega-Board.Thing I already tried: - make it smaller than 1GB by partitioning 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.

miso vs. Sd Card Spi Mode Initialization I'll definitly put it in my layout, I still can solder a 0 Ohm resisistor when I have to decide it's a bad idea anyhow!Thanks again guys. Is the Miso compromised?
The best results are with smd ceramic multilayer capacitors ie. 10u, 22u, etc.
FrankyP Newbie Posts: 10 Karma: 0[add] Re: Micro-SD Card not formatted #14 Jul 29, 2012, 08:38 pm Good point. 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. SCK doesn't need no pullup, seems about right.4. Sd Card Spi Interface Specification Most SD shields connect MISO directly.
FrankyP Newbie Posts: 10 Karma: 0[add] Re: Micro-SD Card not formatted #11 Jul 29, 2012, 07:46 pm Ok, just tried to connect Miso directly to the board. The only sure way to format an SD card to the SD standard is to use SDformatter https://www.sdcard.org/downloads/formatter_3/. And of course it doesn't work :-)The levelshifter shifts the hell out of my signals and the ones coming back from the card(watched it all with my oscilloscope). 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:
SDO probably means SD-Out, so the MiSo and SDI is SD-IN, so the MoSi? 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). FrankyP Newbie Posts: 10 Karma: 0[add] Re: Micro-SD Card not formatted #9 Jul 29, 2012, 04:47 pm Hi fat16lib,I edited the headerQuote#ifndef SdFatConfig_h#define SdFatConfig_h#include
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 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 This may because SdFat does retries during initialization.Arduino does not support hardware CRC but SdFat has software CRC which is normally disabled.Could you please edit SdFatConfig.h at about line 35 and I got several of these left...
