Hi, I am trying bring up MMC in our hardware which is running on PXA270 processor with 128 MB RAM. But i am not able to detect the SDCARD, as it is showing the invalid partition table (the dos partition magic number is not correct, it is 44aa, instead of 55 aa), what could be the problem for such a behavior ? But the same card is working properly in Linux on the same board.
Thanks & regards, -- Vaisakh P S (http://www.google.com/profiles/VaisakhRulez) Here is a log of printfs while doing mmc init: w...@accord$ mmc init mmc_cmd 0 0x0000 0x0000 0x0040 MMC status 0x00002140 MMC resp[0] = 0x000000 MMC resp[1] = 0x000000 MMC resp[2] = 0x000000 MMC resp[3] = 0x000000 mmc_cmd 55 0x0000 0x0000 0x0001 MMC status 0x00002140 MMC resp[0] = 0x000120 MMC resp[1] = 0x000000 MMC resp[2] = 0x000000 MMC resp[3] = 0x000037 mmc_cmd 41 0x0030 0x0000 0x0043 MMC status 0x00002140 MMC resp[0] = 0xff8000 MMC resp[1] = 0x000000 MMC resp[2] = 0x000000 MMC resp[3] = 0x00003f mmc_cmd 55 0x0000 0x0000 0x0001 MMC status 0x00002140 MMC resp[0] = 0x000120 MMC resp[1] = 0x000000 MMC resp[2] = 0x000000 MMC resp[3] = 0x000037 mmc_cmd 41 0x0030 0x0000 0x0003 MMC status 0x00002140 MMC resp[0] = 0x80ff8000 MMC resp[1] = 0x000000 MMC resp[2] = 0x000000 MMC resp[3] = 0x00003f Detected SD card mmc_cmd 2 0x0000 0x0000 0x0022 MMC status 0x00002140 MMC resp[0] = 0x1b534d30 MMC resp[1] = 0x30303030 MMC resp[2] = 0x10b1c8f2 MMC resp[3] = 0xa300993f mmc_cmd 3 0x0000 0x0000 0x0001 MMC status 0x00002140 MMC resp[0] = 0x020500 MMC resp[1] = 0x30303030 MMC resp[2] = 0x10b1c8f2 MMC resp[3] = 0xa3009903 mmc_cmd 9 0x0002 0x0000 0x0002 MMC status 0x00002140 MMC resp[0] = 0x7fff32 MMC resp[1] = 0x5f5983cb MMC resp[2] = 0x76dbdfff MMC resp[3] = 0x9640003f Detected: 1989632 blocks of 512 bytes (971MB) SD card.
