Hello, Community!
I have a problem with reading of 4GB SD Card using FatFs R0.11a, fs_mci.c V1.0 and lpc_mci.c V2.0 on my LPC4088. After initialising everything works, except reading the file. I've found, there is a start bit error in the variable MCI_Data_Xfer_ERR if I call the function MCI_ReadBlock with the parameter numOfBlock>1. For numOfBlock=1 everything works fine and no start bit error occurs.
I can read the card data and the directory, can properly determine file size, I can also read all sectors separately without errors. If I try to read more, than one sector as a block, I get start bit error.
Any ideas? Thx in advance.
See terminal recording:
