Reply To: Tapping into SPI

[Michael P. Flaga]

That is annoying. I experience the same problem occasionally. It seams to come and go on its own. I have to believe it is a problem un-related to the SFEMP3Shield library itself. As it occurs without it. I am suspicious that it may be an electrical issue, like a capacitance or race issue on the start up of the SdCard. At times I have seen it help to stuff another card into Arduino and it works. Where sometimes sticking the afflicted card into a Laptop then reading it and then back into the Arduino sometimes cures the problem, not always. Where my initial thought may be wear and tear or corrosion on the SdCard connector.

Let me know of any progress. We may need to advance it to SdCard author.
