# MIPS ToolChanin can be downloaded from https://www.mips.com/develop/tools/codescape-mips-sdk/ .

# Toolchains with 'mti' in the name (and install directory) are for MIPS R2-R5 instruction sets.
|
|
# Toolchains with 'img' in the name are for MIPS R6 instruction sets.
|
|
# It is recommended to use cmake-gui application for build scripts configuration and generation:
|
|
# 1. Run cmake-gui
|
|
# 2. Specify toolchain file for cross-compiling, mips32r5el-gnu.toolchian.cmake or mips64r6el-gnu.toolchain.cmake
|
|
# can be selected.
|
|
# 3. Configure and Generate makefiles.
|
|
# 4. make -j4 & make install
