**macOS**: Go to https://code.visualstudio.com and click on "Download for Mac"
## Rust Analyzer
## OS specific dependencies
**All**: Open VS Code and look for Rust Analyzer in the marketplace (bottom icon in the left panel). Then install it.
**Windows**: it's OK to ignore the message about `git` not being installed, if you get one
## Rust Cross compilation support
**All**: Run this command in a terminal:
``` console
$ rustup +stable target add thumbv7em-none-eabi
```
## ELF analysis tools
**All**: Run these commands in a terminal:
``` console
$ rustup +stable component add llvm-tools-preview
$ cargo install cargo-binutils
```
## `nrf-recover`
Some nRF52840 devices, specially older revisions, may have parts of their Flash memory locked. To unlock the memory use the `nrf-recover` tool.
This is only relevant to the nRF52840 Development Kit. First connect the nRF52840 DK to your PC using micro-USB J2 (as done before) then run the following commands:
``` console
$ cargo install nrf-recover
$ nrf-recover -y
Starting mass erase...
Mass erase completed, chip unlocked
```
## Cargo subcommands
Install version v0.8.0 of the `cargo-flash` and `cargo-embed` subcommands, as well as the `cargo-binutils` set of subcommands and the `cargo-bloat` subcommand using the following Cargo commands:
``` console
$ cargo install cargo-flash --version 0.8.0 -f
(..)
Installed package `cargo-flash v0.8.0` (..)
$ cargo install cargo-embed --version 0.8.0 -f
(..)
Installed package `cargo-embed v0.8.0` (..)
$ cargo install cargo-binutils
(..)
Installed package `cargo-binutils v0.3.0` (..)
$ cargo install cargo-bloat
(..)
Installed package `cargo-bloat v0.9.3` (..)
```
## Python
**Windows**: Go to https://www.python.org/downloads/ and run the Python *3* installer
- in the installer check the "add Python 3.x to PATH" box
- also run the "Disable path length limit" action at the end, if you are on Windows 10 and the option is displayed to you
**Linux**: Install `pip` using the package manager; this will also install Python.
``` console
$ # Arch Linux
$ sudo pacman -S python-pip
```
**macOS**:
Ensure that you have python 3 and pip installed. Refer to the following link for [Instructions on how to install python 3 and pip](https://docs.python-guide.org/starting/install3/osx/)
```console
$ python --version
Python 3.7.7
$ pip --version
pip 20.0.2 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)
```
## nrfutil
**All**: Open a terminal and install nrfutil as follows. *If you are familiar with python, it is advised to do this in a [virtual environment](https://docs.python.org/3/library/venv.html).*
``` console
$ pip install nrfutil
(..)
$ nrfutil version
