I am using the Digilent PmodSD as the second sd card for the BBB: http://www.digilentinc.com/Products/Detail.cfm?Prod=PMOD-SD
I've been following this forum: http://www.alteraforum.com/forum/showthread.php?t=19335&page=4 but assumes that i have the mmc_spi driver, which isnt found in the 4.1.2-ti-r4 kernel on my beaglebone: mmc_spi.c source file doesnt exist also. root@beaglebone:~# find /lib/modules/`uname -r` -type f -name "*.ko" | grep mmc /lib/modules/4.1.2-ti-r4/kernel/drivers/media/mmc/siano/smssdio.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mmc/host/sdhci.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mmc/host/vub300.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mmc/host/dw_mmc-exynos.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mmc/host/dw_mmc-pltfm.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mmc/host/ushc.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mmc/host/dw_mmc.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mmc/host/sdhci-pltfm.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mmc/host/rtsx_usb_sdmmc.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mmc/card/sdio_uart.ko root@beaglebone:~# find /lib/modules/`uname -r` -type f -name "*.ko" | grep spi /lib/modules/4.1.2-ti-r4/kernel/drivers/misc/ad525x_dpot-spi.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/spi/spi-butterfly.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/spi/spi-lm70llp.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/spi/spi-omap2-mcspi.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mtd/spi-nor/spi-nor.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/scsi/scsi_transport_spi.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/net/wireless/ti/wl1251/wl1251_spi.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/net/wireless/ti/wlcore/wlcore_spi.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/net/can/spi/mcp251x.ko /lib/modules/4.1.2-ti-r4/kernel/drivers/mfd/mc13xxx-spi.ko In another forum, a person solved this by actually interfacing the second SD to the mmc lines: SPI-SD Card <https://groups.google.com/forum/embed/?place=forum/beagleboard&showsearch=true&showpopout=true&showtabs=true&hideforumtitle=true&parenturl=http%3A%2F%2Fbeagleboard.org%2FCommunity%2FForums#!searchin/beagleboard/sdcard$20spi/beagleboard/kEor_xLLEnQ/OzV0f5H53WwJ> I dont see how this will work since mmc1 lines on the p8 header are used by the board. And when i wire my sd card to these lines the Beaglebone doesnt boot up. Also the mmc2 on the p8 header doesnt have a cmd mode pin (mmc2_cmd), so i cant use these lines. There are another set of mmc2 lines on the p9 header but its also missing a mmc2_cmd and a mmc2_clk mode pin. Any insight on how to add a second SD card? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
