# 1. 使用不同的开发板内核时, 一定要修改KERN_DIR
|
||
|
|
# 2. KERN_DIR中的内核要事先配置、编译, 为了能编译内核, 要先设置下列环境变量:
|
||
|
|
# 2.1 ARCH, 比如: export ARCH=arm64
|
||
|
|
# 2.2 CROSS_COMPILE, 比如: export CROSS_COMPILE=aarch64-linux-gnu-
|
||
|
|
# 2.3 PATH, 比如: export PATH=$PATH:/home/book/100ask_roc-rk3399-pc/ToolChain-6.3.1/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin

|
|
# 注意: 不同的开发板不同的编译器上述3个环境变量不一定相同,
|
||
|
|
# 请参考各开发板的高级用户使用手册
