build kernel for AM5xx

1330hayacool7102

hi experts,

I try to build kernel for AM5XX (SDK 2.0.1) and follow steps in processors.wiki.ti.com/.../Linux_Kernel_Users_Guide

And I got problem on generating kernel configuration file , I check ti_config_fragments/README. But I still have no idea about the following command to generate

tisdk_amNNNx-evm_defconfig

./scripts/kconfig/merge_config.sh -m XXXXXX

I don't know XXXX mean which files are included for AM572X because I found lots of files below

[user@ processor-sdk-linux] (processor-sdk-linux-02.00.01)$ ls -l ti_config_fragments/
am33xx_only.cfg connectivity.cfg defconfig_fragment ipc.cfg .README.swp
am43xx_only.cfg debug_options.cfg defconfig_map.txt multi_core_defconfig_fragment system_test.cfg
audio_display.cfg defconfig_builder.README defconfig_merge.sh multi_core_system_test_defconfig_fragment system_test_defconfig_fragment
baseport.cfg defconfig_builder.sh dra7_only.cfg README wlan.cfg

Could you please give a hint about this ?

Thanks

I will ask the software team to look at this.

Just try this:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_am57xx-evm_defconfig

The wiki is a bit unclear on this so I just looked up what configs are there.

Sorry, no. I am on RT-Linux SDK 2.00.01.07.

Hi,

SDK 02.00.01.07 contains the file arch/arm/mach-omap2/tisdk_am57xx-evm_defconfig. Probably there was some kind of failure during the installation. Please download ti-processor-sdk-linux-am57xx-evm-02.00.01.07-Linux-x86-Install.bin from the bellow link:
software-dl.ti.com/.../index_FDS.html

And try again.

If you use another source, and not the official download link (above), then omap2plus_defconfig should work for you.

Best Regards,
Yordan
