From 2fcffe26e815b7125a357c83b59617ab93c16b41 Mon Sep 17 00:00:00 2001 From: Guo Ren Date: Sun, 15 Oct 2017 20:59:34 +0800 Subject: csky: port to uclibc-ng Follow the steps to build c-sky uclibc linux system: 1. git clone https://github.com/c-sky/buildroot.git 2. cd buildroot 3. make qemu_csky_ck810_uclibc_defconfig 4. make Follow the buildroot/board/qemu/csky/readme.txt to run. This buildroot toolchain is pre-build, But you can rebuild the c-sky uclibc-ng alone and install it to the buildroot sysroot manually. We'll try our best to improve the uclibc-ng continuously.
