[Gumstix-users] Gumstix Overo Android boot kernel parameters

Discussion:

I'm using the latest files from the build bot for Android Overo on my
Ironstorm Y. I was able to the the SD card and I set the Kernel parameters
like shown on this link
https://wiki.gumstix.com/index.php/RowboatAndroid#Using_Android.

# setenv anddisplay 'vram=8M omapfb.mode=dvi:1024x768MR-***@60
omapdss.def_disp=lcd43'
# setenv andconsole 'console=ttyS2,115200n8 console=tty0
androidboot.console=ttyS2'
# setenv androot 'root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait init=/init'
# setenv andbootargs 'setenv bootargs mpurate=500 ${andconsole}
${androot} ${anddisplay}'
# setenv andbootcmd 'mmc init; fatload mmc 0 ${loadaddr} uImage; run
andbootargs; bootm ${loadaddr}'
# saveenv

# run andbootcmd being the boot command.

When I run the script changing the path to my SD card I get the error:

Hit any key to stop autoboot: 0
mmc - MMC sub system

Usage:
mmc info - display info of the current MMC device
mmc read addr blk# cnt

mmc list - lists available devices
mmc setdsr <value> - set DSR register value

reading uImage
** Unable to read file uImage **

What could I be doing wrong?

From what I can see, you are trying to run the script `andbootcmd`. The
first step of your script is to run the command `mmc init`, which
doesn't seem to exist based on the `mmc` command list bellow... The
system is telling you that the command `mmc init` doesn't exist.

Hi again,

After a little bit of research, it seems like `mmc init` is deprecatred.
Try to use `mmc rescan` instead.

Let us know if this works.

Hi Fred,

Thank you for the reply. I gave that a try but unfortunately it didn't work
and I'm getting the same error.

The Android Gumstix Github page hasn't had any work done on it since mid
last year, is it worth to keep trying to make it work for this project?

I got the image from that link. I have also tried the ones from
https://buildbot.gumstix.com/builders.

Joe, where did you get your android image? I just check on gumstix's
https://www.gumstix.com/software/software-downloads/
If click on android, then on "Overo Series COM", you get a dropdown menu
with all the things you need to build you android image. You can also find
https://s3-us-west-2.amazonaws.com/gumstix-android/
2015-05-16/overo/dev/uEnv.txt
In this bootscript example, you can see than the image use a zImage (new
way) instead of a uImage (old way). This script is used in a uEnv.txt file,
which will overwrite the u-boot environment variable when placed in the
boot partition. Just try to copy this "uEnv.txt" in your boot partition.
Fred
Hola Joe,
Is it possible you don't have a uImage but instead a zImage?
Check out the 'fatls' command in u-boot. You can use it to examine your
boot partition *as u-boot sees it*.
fatls mmc 0:1

Hi Joe,

I had a look over here: https://www.gumstix.com/software/software-downloads/

I don't see any kernel image for download (nor is there one in your fat
partition). The init ramdisk image is there - I haven't personally tried to
get Android going myself, so you'll want some help from someone else I
guess.

My personal feeling is that there should be a uImage/zImage file on the
gumstix download site and that this should be used with the uinitrd.
Alternatively, perhaps the kernel is in the uinitrd and you can boot from
that.

Assuming the latter, you'd need to change the boot parameters to look for
that file, rather than the uImage file, and then use it to boot. In the
very least, do a fatload, and pass in the address and size of the image to
bootm.

Good luck!

Akram

Joe, where did you get your android image? I just check on
https://www.gumstix.com/software/software-downloads/
<https://www.gumstix.com/software/software-downloads/>
If click on android, then on "Overo Series COM", you get a
dropdown menu with all the things you need to build you
https://s3-us-west-2.amazonaws.com/gumstix-android/2015-05-16/overo/dev/uEnv.txt
<https://s3-us-west-2.amazonaws.com/gumstix-android/2015-05-16/overo/dev/uEnv.txt>
In this bootscript example, you can see than the image use
a zImage (new way) instead of a uImage (old way). This
script is used in a uEnv.txt file, which will overwrite
the u-boot environment variable when placed in the boot
partition. Just try to copy this "uEnv.txt" in your boot
partition.
Fred

Hola Joe,
Is it possible you don't have a uImage but instead a zImage?
Check out the 'fatls' command in u-boot. You can use it
to examine your boot partition /as u-boot sees it/.

Hi Fred,
Thank you for the reply. I gave that a try but
unfortunately it didn't work and I'm getting the same
error.
The Android Gumstix Github page hasn't had any work
done on it since mid last year, is it worth to keep
trying to make it work for this project?

Hi again,
After a little bit of research, it seems like
`mmc init` is deprecatred. Try to use `mmc
rescan` instead.
Let us know if this works.

Hi Fred,

Those were the first files I looked at before I went on to the others on
the buildbot site. Do I need to look for a separate Kernel image file like
Akram mentioned or should those suffice?

Regards,
Joe.

Joe,
Did you try the image here: https://www.gumstix.com/
software/software-downloads/ ?
Fred
Hi Joe,
I had a look over here: https://www.gumstix.com/
software/software-downloads/
I don't see any kernel image for download (nor is there one in your fat
partition). The init ramdisk image is there - I haven't personally tried to
get Android going myself, so you'll want some help from someone else I
guess.
My personal feeling is that there should be a uImage/zImage file on the
gumstix download site and that this should be used with the uinitrd.
Alternatively, perhaps the kernel is in the uinitrd and you can boot from
that.
Assuming the latter, you'd need to change the boot parameters to look for
that file, rather than the uImage file, and then use it to boot. In the
very least, do a fatload, and pass in the address and size of the image to
bootm.
Good luck!
Akram
