Hello,

I`m using ARM STM32F103RBT6. I`m able to record and read data in SD Card with a raw format(Using simple SPI). But I have to use the FAT system because after recorded the card will be read on a PC. Anyone have any library, documentation or example using FAT to help me? Thanks, Vinícius

First I had to change all ''SPI_FLAG_TXE'' to ''SPI_I2S_FLAG_TXE'' After that I was able to compile the code. But Didn't Work, I start the debug and the CrossStudio tell: Error reading Memory. Someone has any idea to make this code works?Has it?

I tried your exemple, but the CrossStudio give a message: 'printf.c:(.text+0x30): undefined reference to `__putchar' Its the only problem, all the rest seems to work pretty well. Could you have any idea how can I solve this problem?
