Hello!
My name is Felipe, I'm from Brazil. I'm trying to do my board save some data in a SD/MMC Card. And when I try to write some data on the card I get a ' Transmit FIFO underrun error ' in MCI_STATUS.
Can anyone help me? I don't really understand what this error means. I'm beginning in this project, so I still don't use DMA.Can that be the problem?
Thank you,
Felipe Avila.
