So, I've (sort of) solved the invisible SD card problem, and have converted it into the recently-reported read-only SD card problem. To do this, I followed the instructions in the thread: http://www.nabble.com/No-MMC-after-OE-flash-td15701810.html wherein I edited the com.gumstix.collection/conf/machine/gumstix-custom-connex.conf file and uncommented the "mmc" MACHINE_FEATURES line. I did not touch the PCMCIA line, not knowing what that might break. I also did the steps of: bitbake -c rebuild task-base-gumstix bitbake -c rebuild gumstix-basic-image as recommended in the thread to update the image,. BUT it DID NOT cause the MMC modules to be added to /etc/modules; I had to do that manually. (Is there a step or dependency I missed here?) Now, I can see the SD card as readonly when I boot the Gumstix with it installed. That's progress... If time permits, I'll try tracing out the NetMMC schematic and attempt to figure out whether the MMC patch actually does the right thing. Unless someone else already knows more about this than I? ----- Each of us has strengths and talents that others don't.

If the card is inserted prior to power up it should automount as /media/card -----Original Message----- From: "Stephen Hersey" <n1...@rc...> To: gum...@li... Sent: 6/3/08 12:25 PM Subject: [Gumstix-users] Of Invisible SD Cards I'm running a Connex 200m with a NetMMC (R1504 board) and a recent (mid-May, rev 318) gumstix-basic-image reflash (default build configuration as pulled from the cvs repo). The Ethernet works great, but I'm unable to mount an SD card (32 MB, FAT format). I've tried hot-plugging the SD card, putting it in before power-up, and neither method allows me to manually mount the device or causes it to automount. Apparently, the /dev/mmcblk0p1 device doesn't even exist, which makes me think I need to reconfigure something to enable SD support. Anyone have an idea what's wrong here?

Hi Stephen, > Now, I can see the SD card as readonly when I boot the Gumstix with it installed. That's progress... I seem to recall that the write-protect/card-detect gpio is different between the verdex and connex and maybe even the basix.
