AM335x Make fails

Prodigy 90 points

hi everyone:

i'm working on beaglebone black platform, using ti-processor-sdk-linux-am335x-evm-02.00.02.11-Linux-x86-Install.bin in ubuntu 14 64bit.

i want to make a new board base on board am335x, so i follow these steps below:

1st. i copy /board/ti/am335, and rename this file to "example", modify the mux.c according to files generated by pinmux v4; modify Kconfig, MAINTAINERS, u-boot,lds.

2nd. copy /configs/am335x_boneblack_defconfig to /configs/am335x_example_defconfig, and modify its CONFIG_TARGET.

3rd. copy /include/configs/am335x_evm.h to /include/configs/am335x_example.h and change macro: CONFIG_SYS_LDSCRIPT

4th. modify /u-boot-2015.07+gitAUTOINC+d49aa5effa\arch\arm\Kconfig, add support to my board, also copy from am335x_evm

then i use command "make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=am335x_example am335x_example_defconfig all" to compile u-boot, but there is an error.

    Hi Ray,

    it seems that you have '.config' file in the root directory of U-boot (it might be created by 'make menuconfig' invocation or something else), while you build it in new directory (with the option O=am335x_example, the appropriate '.config' will be there).

    You can run:

    make CROSS_COMPILE=arm-linux-gnueabihf- mrproper

    to clean the root directory and then:

    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=am335x_example am335x_example_defconfig all

    Regards,
    Yordan

    Hi Ray,

    I did not had any systematic approach to this. I was trying to reproduce the issue without success at the
    beginning so I run 'make menuconfig' to see if I had correctly configured the Kconfig files, and it wrote
    new .config file in U-boot directory and the issue was reproduced (so I guess I had some luck).

    I can recommend to carefully examine the logs when there is an error. For example in the bellow log first 'make'
    command enters the 'am335x_example' subdirectory (because of O=''argument) and all following prints are related
    to actions there (writing .config, generating Makefile etc. are in this directory). The first error message indicates
    that the upper (the root of U-boot tree) directory is not clean which means that probably there was some 'make'
    invocation which has created something there (also there is suggestion how to proceed in the message).

    $ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=am335x_example am335x_example_defconfig all
    make[1]: Entering directory `/home/users/ykamenov/projects/ti/sitara/ti-processor-sdk-linux-am335x-evm-02.00.02.11/board-support/u-boot-2015.07+gitAUTOINC+46c915c963/am335x_example'

    i didn't notice the tip ".. is not clean, please run 'make mrproper" appeared in my compile output.
    may be i need more careful next time...^_^
    thank you very much
