Tool/software: Code Composer Studio
I have a problem with SDIO exchanging data.
When I read data from SD card it goes normally. Before reading transaction I'm waiting for BRR flag of MMC_STAT and when it sets to 1 I make a reading,
But when I try to write some data into block of SD card it has a problem. When I'm waiting for BWR it doesn't set to 1. It's equal to 0 always.
