The blinking LED has stopped when DP2[6] is set to ON, and DP2[7] is set to off. This also enables the top SD slot on the board (CN12). I've yet to get the bottom slot to show any life. The user manual seems to indicate (Section 4.4) that slot usage is an OR situation setup with the DIP switches, that is one can use the MMC interface OR the SD interface but not both. "MMC/ MMC plus/ SD card slot of CN12 is a multi slot that can insert MMC /MMC plus card and SD card. MMC/ MMC plus card or the SD card interface is selected by setting dip switch DS2-[7:6]." dmesg does report the following: sdhci: Secure Digital Host Controller Interface driver sdhci: Copyright(c) Pierre Ossman mmc0 at 0xa4ce0000 irq 100 mmc1 at 0xa4cf0000 irq 23 So given that the top slot works now for me, getting the bottom slot to work isn't critical. But I'll continue to poke at it. > Cheers, > > / magnus > -- > To unsubscribe from this list: send the line "unsubscribe linux-sh" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html >
