Compiler/AM4378: Cannot configure and compile U-Boot

Part Number: AM4378

Tool/software: TI C/C++ Compiler

Hi, We have our own board based on the AM4378 evm. We need to make changes to U-Boot. I have made those changes and need to compile it. I believe I have configured the board and am

http://processors.wiki.ti.com/index.php/Linux_Core_U-Boot_User%27s_Guide#Setting_the_tool_chain_path   I keep getting the error "No rule to make target 'am43xx_evm_deconfig' when iI call the compiler with the following command make am433x_evm_deconfig The above line indicates that I should use am433_evm_deconfig

Also I get the error Makefile 487: *** "System not configured - see README" when I issue the command make CROSS_COMPILER  clean or any other CROSS_COMPILER  command. I have run the mkconfig with no errors, etc.

Also does the U-Boot code need to be in another directory structure other than the one that it resides in from the SDK?

Thanks for your help Ed

    Hello Ed,

    The proper way to build the U-Boot in Processor SDK is to run a make u-boot command from the top SDK directory. The top-level makefile will take the cross-compile paths, configure files for U-Boot and kernel from Rules.make.

    If you check the Makefile you will see that it does these steps:

    $ make -C board-support/linux-4.9.41+gitAUTOINC+e3a80a1c5c-ge3a80a1c5c/ ARCH=arm CROSS_COMPILE=$(pwd)/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- tisdk_am437x-evm_defconfig
    $ make -j 2 -C board-support/linux-4.9.41+gitAUTOINC+e3a80a1c5c-ge3a80a1c5c/ ARCH=arm CROSS_COMPILE=$(pwd)/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- am43x-epos-evm.dtb am437x-gp-evm.dtb am437x-gp-evm-hdmi.dtb am437x-sk-evm.dtb am437x-idk-evm.dtb am437x-idk-pru-excl-uio.dtb

    $ make -j 2 -C board-support/u-boot-* CROSS_COMPILE=$(pwd)/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- am43xx_evm_config
    $ make -j 8 -C board-support/u-boot-* CROSS_COMPILE=$(pwd)/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- DTC=$(pwd)/board-support/linux-4.9.41+gitAUTOINC+e3a80a1c5c-ge3a80a1c5c/scripts/dtc/dtc

    Best regards,
    Kemal

    Hi Kemal, That did it, I was at too low a directory level. I was missing a package for the compiler, but U-Boot now compiles and get me the data I was looking for, it isn't booting completely, but I can find that.

    Thanks For all of your help.
