risc-v 编译 linux,linux - 如何为RISC-V编译Linux Kernel 4.20 - 堆栈内存溢出
这可能没有用，因为您使用了目标riscv-defconfig而不是defconfig - 请参阅Chris Stratton在评论中的暗示。
ls -l arch/riscv/configs/
total 4
-rw-rw-r-- 1 user user 1641 Mar 5 11:59 defconfig
此后的命令集能够使用Bootlin'流行边缘'工具为riscv构建一个4.20.14内核：
wget https://toolchains.bootlin.com/downloads/releases/toolchains/riscv64/tarballs/riscv64--glibc--bleeding-edge-2018.11-1.tar.bz2
wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.20.14.tar.xz
tar jxf riscv64--glibc--bleeding-edge-2018.11-1.tar.bz2
tar Jxf linux-4.20.14.tar.xz
export CROSS_COMPILE=$(pwd)/riscv64--glibc--bleeding-edge-2018.11-1/bin/riscv64-buildroot-linux-gnu-
cd linux-4.20.14
