I am trying to use FAT on zynq7020. I am currently trying to learn how to initialize the MMC card. I have two questions:
In xsdps.c file line 2947 to read CID, XSdPs_ReadReg16 function is used 4 times to read 128 bit register. I think it should be replaced with XSdPs_ReadReg to read 32 bit registers. Is there a point I don’t understand or miss?
Relative addreses of eMMC is set 0x12340000. Is there any specific reason not to set 0x0000000?
