Hello, I am having some troubles with mmc cards. I've been putting together some demos using gumstix boards purchased in october and 128MB MMC cards purchased from gumstix last week, which has been going fine. However for my last demo, I needed to use a gumstix board from August with a new card, which didn't work. I tried updating the u-boot image from r48 to r152, which allowed me to see the new cards in u-boot, but now the MMC doesn't show up under linux. Even the one old card I have here doesn't show up in linux anymore. I am trying to mount /dev/mmc/mmc0/part1, which works fine on new boards with new cards, but with the u-boot update gives the following error: # mount -t vfat /dev/mmc/mmc0/part1 /mnt/mmc mount: Mounting /dev/mmc/mmc0/part1 on /mnt/mmc failed: No such device or address # The rootfs image I am using is ~ 1 month old and I don't especially want to check out a new one since I made some kernel mods and the current buildroot was working fine with whatever u-boot was coming on the new boards. So does anyone have an idea on how to make linux see the MMC again? Maybe I need to do a mknod or something? Alternately, if someone had a copy of the u-boot.bin which is shipping on new boards that would probably work, given that the new boards work fine with the new cards and this root_fs I am using. Thanks for any help, -Holly (trying to get 5 demos ready to ship with less than 1 hour left to go...) |

Holly, I think I changed the location of the mmc node under /dev -- so you might not have /dev/mmc/mmc0/... I think /dev/mmc/mmc0/part1 used to be called /dev/mmcblk0 mkdir -p /dev/mmc/mmc0 mknod /dev/mmc/mmc0/disk b 254 0 mknod /dev/mmc/mmd0/part1 b 254 1 C On Dec 6, 2004, at 2:36 PM, Holly Gates wrote: > So does anyone have an idea on how to make linux see the MMC again? > Maybe I need to do a mknod or something? |

The shipping u-boot is the latest one that's on sf.net C On Dec 6, 2004, at 2:36 PM, Holly Gates wrote: > Alternately, if someone had a copy of the u-boot.bin which is shipping > on new boards that would probably work, given that the new boards work > fine with the new cards and this root_fs I am using. |

Thanks Craig, it looks like this issue was actually two things compounded: 1) old version of u-boot (1.1.1 from July 23) can't read new cards . I tried another old board and updated the u-boot to a newer version (1.1.1 from Oct 3, the one off sourceforge) and it can read the new cards fine now. 2) one of my old boards can't seem to see the mmc card from linux. This is what was confusing me last night. I thought this problem started when I updated the u-boot on this board, but probably it was never seeing the mmc card at all. I have no idea why this is happening since u-boot can see the card fine, but then it doesn't show up in linux. There is no message from MMC during bootup or in dmesg either, like there is normally. This is using the same kernel/filesystem image that I have been using on the other boards. Maybe there is some kind of hardware problem on this board... Anyway, thanks for the help. I guess I'll just not use that one board for now. -Holly Craig Hughes wrote: > The shipping u-boot is the latest one that's on sf.net > > C > > On Dec 6, 2004, at 2:36 PM, Holly Gates wrote: > >> Alternately, if someone had a copy of the u-boot.bin which is shipping >> on new boards that would probably work, given that the new boards work >> fine with the new cards and this root_fs I am using. > > > > > ------------------------------------------------------- > SF email is sponsored by - The IT Product Guide > Read honest & candid reviews on hundreds of IT Products from real users. > Discover which products truly live up to the hype.

Holly, if you don't need it for something else in the short-term, mail it back to us and we'll send you a replacement -- I can then also take a look and see if I can figure out what's wrong with it.

I am having the same problem and the same message you outlined. I built the new flash image from the rungie.com website (r252 I think) and like you I can see MMC in u-boot but the SD card I have fails. When I boot into Linux the MMC just reports no device. Under version r161 that came installed on the gumstix both the MMC card and the SD card worked just fine so I am guessing it is just a software problem.

I'll take a look at the linux stack -- it's possible that while I was working on it a few months back I forgot to commit a change or something. Could also be an update to the stuff I was working from which can be merged in now.
