Dear All,

I load and did all steps for GPT compiling and then try to compile kernel I got this error;

met@met:~/Desktop/Compile_Ubuntu_firmware(GPT)/linux/linux-sdk$ ./build.sh kernel
============Start build kernel============
TARGET_ARCH =arm64
TARGET_KERNEL_CONFIG =firefly_linux_defconfig
TARGET_KERNEL_DTS =rk3399-firefly

What is problem?

Best regards,

Think firstly have to define compiler tool chain so then used export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu- and try again, compiled but now same as for uboot. So for uboot which croos compile tool chain must be used and what must be the ARCH?

The ARCH & CROSS_COMPILE should be taken care of in the build.sh.

What’s your compiling environment? We pass all builds in 64bits Ubuntu 16.04,
using ext4 or xfs filesystem.
