Hi,
im trying to develop and sdio driver modifying the existing SD card driver.
Im using an OMAP processor and a Wifi SDIO Card.
I have send CMD 5 to get the OCR.
i do get the EOC Status bit set.
I do get the response resp[0] => 0x10fff000 (Contents of RSP6 & RSP7)
According to this -> ocr => 0xfff000 (right most 24 bits)
mem present => 0
No of IO functions => 1
I am using a Wifi SDIO Card - am not sure if these values are correct?.
Am i doing something wrong here?
I understand from the SDIO specs that only one of the bits (0-24) must be set.
How do u interpreset an ocr of 0xfff000 ?.
#define MMC_RSP_R4 (MMC_RSP_SHORT|MMC_RSP_CRC)
#define SDIO_IO_SEND_OP_COND (5)
cmd.opcode = SDIO_IO_SEND_OP_COND ;
cmd.arg = 0;
cards.flags = MMC_RSP_R4
Is this wrong?
Regards,
Jo
