Generating uImage on AM335x- Starter Kit ?

Martin Boudreault
Prodigy 110 points

Hi, 

I'm currently working on modifying the linux kernel for an Android Application on the AM335x Starter Kit board.

Following TI's guide for Android development (http://processors.wiki.ti.com/index.php/TI-Android-ICS-4.0.3-DevKit-3.0.1_DevelopersGuide) I tried to build the kernel and generate its image so I can boot the board using the SD Card with :

  $ make ARCH=arm CROSS_COMPILE=arm-eabi- distclean
  $ make ARCH=arm CROSS_COMPILE=arm-eabi- am335x_evm_android_defconfig
  $ make ARCH=arm CROSS_COMPILE=arm-eabi- uImage

But the build wouldn't work. I looked back to the guide and saw :

      NOTE:Genrated uImage run on both am335xevm and beaglebone.

Does this means it is impossible to generate the kernel image on the AM335x Starter Kit board (am335xsk) ?

Is there another way (other than this procedure)  I could build and generate an image of the kernel to boot from an SD Card ? 


Thanks !

    Martin,

    It looks like support for the SK (Starter Kit) was added through the below page:

    http://processors.wiki.ti.com/index.php/AM335X_EVM-SK_Android_Devkit_Guide

    I hope this helps you.

    Hi RonB,

    Thanks for the quick answer. Unfortunately, the procedure is exactly the same, and so is the result. 

    If it help, here is the output I get from building :

    Martin,

    This lines concerns me:

    kernel/bounds.c:1:0: error: bad value (armv5t) for -march= switch

    Can you provide the output of all 3 steps as well as your path?

    Thanks.

    Of course.

    Here is the cleaning step

    Based on what I see, are you missing "/Development" in front of the toolchain in your path?

    I did, but just after posting it, I changed it, with no difference.The errors are exactly the same. 

    Something is really weird. Looks like it fails to build before even reaching the compiler.

    ... looks like it was another typo mistake that caused the error. 

    I had CROSS-COMPILE, instead of CROSS_COMPILE...

    Sorry to have troubled you with this. 

    Thanks for your time, and special thanks to Pankaj Bharadiya who has seen the error.
