Hello,


has somebody tried to use DAT0-DAT3 (aka wide bus) with micro SD cards? I am always getting the Data block sent/received failed, DATACRCFAIL. The same behavior with 32GB kingston and 2GB Adata. Only a confirmation would be appreciate, it means that I am doing a wrong configuration.


Thanks,


Martin

Hello again,


I did a school mistake :). I have configured the SD Card with 0b100(0x4) argument for the ACMD6 instead of 0b10(0x2) and the switched the lpc's controller to a wide bus.
