I am having a problem talking to an SanDisk iNAND device (P/N: SDIN4C2-4G-U). This device is connected to the MMC0 port on my DM365 custom hardware. The symptom I am seeing is that I never get the /dev/mmcblk0 device to show up. Here is a log of my Linux kernel startup; Note around 7.00s after startup there being some timeout erros messages. Can someone help me determine what this driver is or is not seeing? I am seeing a 200KHz clk and data on the CMD lines.
