Hello, I am trying to read Cis Data from u-boot. I find that the response to CMD5 is 0x90ff8000. The Number of I/O functions is 1. I use a WLAN Card. Wlan cards usually have 2 functions. is something wrong? How to de-code this response - Is OCR = 0x90FF? I read that the 28,29,30 Bits are the I/O functions. am i missing something? I find that When i try to send CMD0 and CMD5 all over again. The card does not respond. Are there any sample codes to read the vendor Info like Vendor ID? Thank you very much, Regards, John -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
