 The purpose of this webpage is to explain how to get the GNU ARM Embedded Toolchain running in Centos 7.3 (x86_64) I had the specific purpose of trying to build the firmware for the Tyt MD-380 hand-held radio.
More details about the Experimental firmware can be found HERE
Overview:I suggest that you do not try to use the GNU ARM Linux tools that are part of the standard EL7 repo.
Instead I suggest downloading the toolchain from a specific website and performing the neccessary changes to make the compiler work in Centos 7.3.
How to install the toolchain:Step 1: Download the latest Linux 64-Bit toolchain from: Developer.arm.com When I wrote this guide, the current version was gcc-arm-none-eabi-6-2017-q2-update-linux
cd /opt wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/6-2017q2/gcc-arm-none-eabi-6-2017-q2-update-linux.tar.bz2 bunzip2 gcc-arm-none-eabi-6-2017-q2-update-linux.tar.bz2 tar xvf gcc-arm-none-eabi-6-2017-q2-update-linux.tar Step 2: Edit the global default bashrc so the compiler will be found vi /etc/bashrc Add to the bottom of the file the following: (assuming the same version was downloaded) PATH=$PATH:/opt/gcc-arm-none-eabi-6-2017-q2-update/binsave the file, logout, login again to activate the new path Step 3: Create the missing shasum During the compile of the experimental firmware, the make process failed stating that shasum was missing. We can easily create a script to provide the missing functionality vi /usr/bin/shasum Add the following 3 lines to the new file: #!/bin/bash shift 2 sha256sum $@ After you have saved the file, change the permissions: chmod 755 /usr/bin/shasum Step 4: Enjoy the ARM cross compiler!
