3+
## 1) Download and install the gcc toolchain
4+
5+
You can download and compile the toolchain from the official GCC repository.
6+
7+
A toolchain that has been used and verified is [gcc 14.2.0](https://github.com/bao-project/gcc-v850-elf-toolchain/releases/download/v14.2.0/gcc-14.2.0-v850-elf.tar.gz).
8+
9+
10+
## 2) Download and install rfp-cli
11+
12+
You can download `rfp-cli` for linux [here](https://www.renesas.com/rfp).
13+
Add it to your PATH.
14+
15+
```
16+
rfp-cli --version
17+
Renesas Flash Programmer CLI V1.11
18+
Module Version: V3.18.00.000
19+
```
20+
21+
## 3) Build a demo
22+
For example to build the baremetal demo:
23+
24+
```sh
25+
export CROSS_COMPILE=v850-elf-
26+
export DEMO=baremetal
27+
export PLATFORM=rh850-u2a16
28+
29+
make
30+
```
31+
32+
## 4) Flash bao.bin and guests to board
33+
34+
You must use the `rfp-cli` tool to program the `bao.bin` and guest images.
35+
Please take a look at the corresponding demo instructions for this platform.
