Currently we are developing our product around OMAP-L138 SOM using L138 dev kit.
We have chosen SD card for our primary storage, and I have successfully brought up a system
with root file system on it. But when I tried to move up to booting uImage off SD card,
I didn't find SD/MMC card support on u-boot built for L138 dev kit (da8xx board).
First I throught it was simply not enabled in the build configuration, but taking a closer look,
it seems that DaVinci processors have different SD/MMC controller from OMAP3 and
the MMC driver drivers/mmc/omap3_mmc.c does not work with L138.
Since TI added L138 SD/MMC card support in the kernel, do you have any plan to add
same support for u-boot in (very) near future?
Hello,
Yes, there is a plan to support MMC/SD in U-Boot on OMAP-L138 and patches should be submitted to U-Boot mailing list in the near future. I will confirm the approximate ETA to you.
Thanks,
Sekhar
Hi Sekhar,
That is great! Looking forward to seeing that patch. Thank you.

Shibuya-san,
There was another thread regarding this where I posted the code details.
Please see: http://e2e.ti.com/support/embedded/f/354/p/43807/171520.aspx#171520
Apologize for not keeping this thread updated.
Thanks,

Hi Sekhar,
I finally got around to try this out. Somehow I couldn't get fatload working:

I followed instruction in http://code.google.com/p/beagleboard/wiki/LinuxBootDiskFormat for SD card formatting.
BUT, then I tried out ext2 file system instead of FAT, noticing the existance of new ext2ls and ext2load command in u-boot, and that worked perfectly for me. I could boot from uImage in ext2 partition with root file system placed in the adjacent ext3 partition.

Hi Hiroto,
I'm trying to do the same as you but I have problems accessing to the SD/MMC.
I add the options that Sekhar Nori said at the end of the da850evm.h config before recompile the u-boot:
The MMC/SD support for DA850EVM is done through the Generic MMC framework
of u-boot. Following options shall be enabled in the default configuration
to include MMC/SD support.
CONFIG_MMC
CONFIG_GENERIC_MMC
CONFIG_DAVINCI_MMC
CONFIG_CMD_MMC
To include File system support for MMC, following configuration options
shall be enabled
CONFIG_DOS_PARTITION
CONFIG_CMD_EXT2
CONFIG_CMD_FAT
Then I write the ubl and the u-boot to the SPI flash, the u-boot print out this, and mmc commands are added, but doesn't work:

I don't know what I am doing wrong. Could you tell me what did you do to compile a u-boot with SD/MMC support?
Thanks,
Cerilet.
Hi Cerilet,
Did you build from repository pointed at by that post? Actually, I'm not so sure why he had to mention the config change because when I pulled from
http://arago-project.org/git/projects/?p=u-boot-omapl1.git;a=shortlog;h=refs/heads/mmc
it was all already configured properly as you can see in dm850's configuration file:
http://arago-project.org/git/projects/?p=u-boot-omapl1.git;a=blob;f=include/configs/da850evm.h;h=fb96f896d7d41cddce536034c98178303e9532bc;hb=refs/heads/mmc
So I didn't have to do anything to configured it. All I did was make the following change in the u-boot recipe to point to that branch and bitbake it.
http://e2e.ti.com/support/embedded/f/354/p/43807/192577.aspx#192577
Here is the boot message I see from my build:

Thanks for your quick response Hiroto.
I'm compiling the u-boot from the source of DaVinci-PSP-SDK. I can't find the file arago/recipes/u-boot/u-boot_git.bb to modify it.
I look for information but I can't find nothing.
I have never used neither git nor bitbake and am a bit lost.
Cerilet,
The u-boot code in DaVinci-PSP-SDK does not have support for SD/MMC support for L138 EVM. You have to pull the code from the git repository specified in:
http://e2e.ti.com/support/embedded/f/354/p/43807/153307.aspx#153307
$ git clone git://arago-project.org/git/people/sekhar/u-boot-omapl1.git;protocol=git;branch=mmc
Hi Hiroto,
finally I could download the right source code. I had problems executing git on a virtual machine (maybe port problems). I executed on a machine with an installed ubuntu and could download it:
user@host:~$ git clone git://arago-project.org/git/people/sekhar/u-boot-omapl1.git;protocol=git;branch=mmc
I build the u-boot but this source haven't support the mmc. I had to download the source code clicking on the snapshot link at the arago webpage.
Finally I build it and loaded. It seems to load the driver but didn't detect any card:

I tried several cards, and the output is the same. Maybe because I am using SD instead MMC? I don't think so.
It's really strange, because I downloaded the kernel from the arago webpage also and it hasn't support the SD card? But in the menuconfig is set. I'm getting frustrated...
Thanks again for helping me.
After pulling from the git repository, did you set it to "mmc" branch? If you just pulled, you are in master branch which does not have mmc support.
$ git branch
master
$ git branch -a
* master
origin/DAVINCIPSP_03.20.00.08
origin/HEAD
origin/master
origin/mmc
origin/wakeup
# now creat local branch "mmc" from "origin/mmc" and switch to it
$ git branch mmc origin/mmc
$ git checkout mmc
Switched to branch "mmc"
# Now, you have the source with mmc support.
I'm also using SD card. Just a regular SanDIsk 2G SD card I picked up at local office supply store.

After execute the git commands I execute nexts to compile u-boot. Are they correct?
host$ make distclean CROSS_COMPILE=arm-none-linux-gnueabi-
host$ make da850_omapl138_evm_config CROSS_COMPILE=arm-none-linux-gnueabi-
host$ make all CROSS_COMPILE=arm-none-linux-gnueabi-
Then I copied the u-boot.bin to windows and execute the serial flasher on MS-DOS:
C:\SerialFlasher\sfh_OMAP-L138.exe -flash ubl_OMAPL138_SPI_MEM.bin u-boot.bin
If is correct this procedure maybe the problem are my 6 different SD cards, I don't think so.
Anyway, could you send me your UBL, U-Boot and kernel (if yours has support for SD/MMC) by mail to try if works or do the same? cerilet (at) yahoo.com.
There is no way to do nothing with de SD card. I will thy this and leave it if doesn't works. I can't waste more time on this.
Thank you so much for your kind help Hiroto.
Hi Cerilet,
Are you really running on da850 hardware?
http://www.logicpd.com/products/development-kits/zoom-omap-l138-evm-development-kit
> Bus Width: 1-bit
You output claims that Bus width is 1-bit, but on L138 EVM kit, the bus width is 4. Are you running on custom hardware using L138 SOM?
Yes, I am using Zoom OMAP-L138 Experimenter Kit which is the same as the EVM but without the user interface board:
http://www.logicpd.com/products/development-kits/zoom-omap-l138-experimenter-kit
I think the problem is because doesn't load the driver well.
When I start the kernel, it recognizes 4-bit mode but doesn't works anyway:
root@da850-omapl138-evm:~# dmesg | grep mmc
davinci_mmc davinci_mmc.0: Using DMA, 4-bit mode
I don't know why the TI support don't say nothing...
Could you send me your images, please?
Thank you.
Hello,
I assume you are not able to get MMC/SD working on the EVM even with pre-build kernel image from latest SDK.
The first thing to check is if the card detection that is built into the MMC/SD slot on the EVM is malfunctioning for some reason.
Can you try to comment out the "get_cd" function pointer assignment in the davinci_mmc_config structure in arch/arm/mach-davinci/board-da850-evm.c.
With this the kernel will not use a GPIO to detect the presence of the card, but will detect its presence by actually trying to read the card.
Thanks,
Sekhar
Hello Sekhar,
yes, I tried with the pre-build kernel uImage and nothing.
I inspected the EVM and I didn't see anything broken. I just unbox the EVM and put it on the table.
I did what you suggest but the problem remain.
I add all the startup code, maybe you'll see something wrong.
Thanks,
Cerilet.

Hi Sekhar,
could you send me a U-Boot and kernel with SD/MMC support by mail? cerilet (at) yahoo.com.
I think the device is not working properly.
Thanks,
Cerilet.
The driver seems to be loaded, but I can't get access to the SD:
