[U-Boot] Building u-boot for iMX28 and getting error in mkimage of missing command line parameter CONFIG_IMX_CONFIG

[Bill]

All,

     I am working on building the latest u-boot for the imx28evk board.  
I have done the following steps:

1. git clone git://git.denx.de/u-boot-imx.git
2. setup paths for finding my cross-compiler
1.  make mx28evk_config
2.  make u-boot.imx
3.  It then gets through most of the build process and then fails on 
this command line:

                $ tools/mkimage -n -T imximage -e 0x40000100 -d 
u-boot.bin u-boot.imx

after more digging, its looks like the CONFIG_IMX_CONFIG var is not 
getting filled in (I believe this value should follow the -n parameter)

Thanks,
Bill

'make u-boot.imx'  is not correct for mx28.

You should do:

make u-boot.sb

Please follow the instructions at doc/README.mx28_common for the
correct process.

Thanks.  That did it!


However, now my new U-boot built from the mainstream Uboot runs and also 
loads and unpacks the Linux kernel - but it dies after that.  However, 
my original U-boot from tlib works fine.  Are there some patches and/or 
settings I am missing?

Thanks,

Bills

I suppose you are using the 2.6.35 kernel. In this FSL kernel the
console is ttyAM0.

In mainline kernel the console is ttyAMA0.

This is probably the reason you don't see nothing in the console.

I would suggest you to use the mainline kernel though.

[Bill]

Thanks.  I tried that and got the same results.  Are there any 
debug/logging that I can use to see what's going on?

Also, I'm not sure which console parameters are passed to the kernel.  
I've seen console,  console_mainline, console_fsl, etc...   Which one is 
actually passed as command line params to the kernel?

Thanks,
Bill

I just tried it here and 2012.07-rc3 does not boot for me too.

I started another thread on that.

I suggest you to use 2012.04.01.

I was using the wrong LOADADDR for mx28, and that's the reason it did not boot.

What is the error you are seeing? Can you post your log?

Here is the log on 2012.07-rc3:

Here is my log.  It stops at the "done, booting kernel."    I tried 
setting the console to ttyAM0 and no change.  I don't think its booting 
as I don't see the LCD flash and no penguin.  The odd this is that I 
built the latest kernel for iMX and this uboot will boot it.   I also 
included my u-boot environment settings at the end.

Thanks,
Bills

Do you mean you are able to boot a mainline kernel, but not a 2.6.35 kernel?

Please change it to ttyAM0.

If you boot a 2.6.35 you need to use ttyAM0.

> console_fsl=console=ttyAM0console_mainline=console=ttyAMA0netargs=setenv

This line seems to be without any spaces. Are you sure this is correct?

Make sure your kernel command line passes ttyAM0 instead of ttyAMA0 if
you want to boot a 2.6.35 kernel.

[U-Boot] Building u-boot for iMX28 and getting error in mkimage of missing command line parameter CONFIG_IMX_CONFIG

[Bill]

Progress!   I switched all the references from ttyAMA0...   to ttyAM0.  
Also changed netargs too.  Now it starts to boot linux but hangs right 
after the line of:
     mxs_cpu_init:  cpufreq init finished.
In regards to your question, yes it was booting the mainline kernel.

Here is the latest output from the boot.
