fsl_sd.c issue

Hi All,

 I'm trying to incorporate SD-card support, based on the SDK's fatfs example, into my own project.

I have the pins and clock plumbed without conflict. And card detection works. However, whenever I try and format the card ( using f_mkfs() ), or do any write operation really, things get hung up.


f_mkfs() calls SD_Write() in fsl_sd.c which then goes to check status but never returns. What would cause this?


/* Wait for the card's buffer to be not full to write to improve the write performance. */
