I'm trying to get the "app" that was provided running from a 4GB uSD card. Right now, it can detect the presence of the card but isn't able to initialize it.
In the starterware code, it first resets the card which returns ok, but then when it goes to check the card type, it returns with a failure status. Looking into it more deeply, it seems to timeout during a loop while sending a CMD55. I've tried changing it to a CMD8 like some have suggested and it still doesn't work.
Thank you for any help.
