@all, I google some information about this topic and then, i found the case is that jut support "CodeSourcery labs" toolchain. I think my external toolchain is not standard of directory like "tcmode-externl-csl". I can use "buildroot" to use this toolchian that just use three variables following : BR2_TOOLCHAIN_EXTERNAL_PREFIX BR2_TOOLCHAIN_EXTERNAL_PATH BR2_TOOLCHAIN_EXTERNAL_SYSROOT_PATH
so there are some solution in poky ? thanks for you attention :) B.R. -- jojo
