Setting up SDIO interface on F4 -CMD2 issues

Hi guys,

I'm currently setting up an SD Card on the STM32F4 Discovery and have managed to so far get through the initial setup commands without too many issues. CMD0, CMD8,CMD55,CMD41 have all successfully been sent and the responses I've got back have been what I've been expecting. I'm now at the stage where I'm sending CMD2 though and I'm picking up a CTIMEOUTC flag in the status register with no response detected on the line. Been looking everywhere to try and find out why I might not be getting a response but can't find anything. Anybody got any ideas or insights?

Cheers!
