U-Boot ignoring uEnv.txt-settings

[meino....@gmx.de]

Hi,

I took the u-boot.img and MLO from the angström distribution
and tried to do some setting with the uEnv.txt file.

None of the setting were available neither when u-boot is interrupted
and printenv was used to proof the environment setting nor show
cat /proc/cmdline any changes of the kernels commandline.
"Reading uEnv.txt" (or similiar...dont remember exactly) was shown
though.

How can I make u-boot accept, read and use the setting in my uEnv.txt?

Best regards,
mcc

A copy of your uEnv.txt and serial boot log would be awfully helpful,
here.

What is the goal of these settings?
Where do you expect to find them used and for what purposes?

ip_method seems to be set to 'none' by the u-boot tree you're using as
the default. The other two, 'i2c_bus' and 'server_ip' don't seem to
appear to be useful in u-boot.

These are environmental variable from the point of view of u-boot,
Andrew.

I expect to see them after a printenv command from the "u-boot
shell".

The purpose and goal are irrelevant for u-boot.

Are you typing "printenv" before or after u-boot loads "uEnv.txt"...
As the one should expect, new variables introduced by "uEnv.txt"
shouldn't exist prior to loading "uEnv.txt"..

Hi Robert,

I redone the experiment several times and you are right: It is before
uEnv.txt is read.
Is there any chance to proof that uEnv.txt is read from the later
userland?
May be cat /proc/cmdline?

Best regards,
mcc

Yeah, look at your "uEnv.txt" and put a "printenv; " right before the
bootm/bootz call..

Hi Robert,

before I brick my bone ... (I am no boot-guru...)

Where Do I have to do that?

Is this correct:
Reboot bone
Hit <SPACE> when U-Boot asks for it
Modify commands as described via setenv
run bootcmd

Is this correct?

Thank you very much for your help in advance!
Best regards,
mcc

Nope it is not... You need to actually look in your "uEnv.txt" file...

Using (for reference only): http://elinux.org/BeagleBoardUbuntu#BeagleBone_2

I have set:

loaduimage=run xyz_mmcboot; run mmcargs; bootz 0x80300000
0x81600000:${initrd_size}

so i would change it to:

loaduimage=run xyz_mmcboot; run mmcargs; printenv; bootz 0x80300000
0x81600000:${initrd_size}

**Warning, if your uEnv.txt does not have something similar, then you
need to hit "printenv" first and actually figure out what variable
(probably loaduimage) you need to add to "uEnv.txt" and properly
modify with "printenv;"

Hi Robert,

with your help and infos I could verify that uEnv.txt gets loaded and
"executed". Thats good news.

Thank you very much for help and support! :)
