###### Note about gcc-arm-embedded on Ubuntu 14.04 and later
|
||||
|
||||
If you are using Ubuntu 14.04 and later, please be careful because
|
||||
there are packages with same name but produced by Debian and inherited
|
||||
by Ubuntu. Simply follow the above 3 steps, you may end up with
|
||||
gcc-arm-none-eabi from Ubuntu. So to install gcc-arm-none-eabi from
|
||||
ARM, steps are:
|
||||
|
||||
```
|
||||
1). sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi
|
||||
2). sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
|
||||
3). sudo apt-get update
|
||||
4). sudo apt-get install gcc-arm-none-eabi=4-8-2014q2-0trusty10
|
||||
```
|
||||
Meanwhile we are working with Debian to consolidate and unify this toolchain.
