#### How-to-use 

* Compile and upload [`PortentaX8_EchoServer`](https://github.com/arduino/ArduinoCore-mbed/blob/main/libraries/RPC/examples/PortentaX8_EchoServer/PortentaX8_EchoServer.ino)

```bash

arduino-cli compile -b arduino:mbed_portenta:portenta_x8 -v libraries/RPC/examples/PortentaX8_EchoServer -u

```

* Build the Go [`example`](example/sample_mprpc.go) application and upload to Portenta X8

```bash

cd example

GOOS=linux GOARCH=arm64 go build

adb push example /home/fio

```

* Login your Portenta X8 and execute the `example` application

```bash

adb shell

./example

```

* On your PC open a terminal via the Portenta X8's `tty/ACMx` serial interface and interact with the M4 sketch

```bash

ll /dev/serial/by-id/*

lrwxrwxrwx 1 root root 13 Jän 19 07:43 /dev/serial/by-id/usb-Arduino_Portenta_X8_2D16BA09DAB6FAD9-if02 -> ../../ttyACM0

minicom -D /dev/ttyACM0

...

```

#### How-to-debug

**Note**: the [`proxy`](proxy/main.go) is built into the Yocto image via this [recipe](https://github.com/arduino/meta-partner-arduino/blob/main/recipes-connectivity/m4-proxy/m4-proxy.bb). Should it become necessary to debug and build a custom version you can also build it on your PC and then push and execute it on the Portenta X8.

```bash

cd proxy

GOOS=linux GOARCH=arm64 go build

adb push proxy /home/fio

```

Before starting the locally built proxy make sure that the one automatically started as a service is disabled.

```bash

ps -A | grep m4_proxy             

   3159 pts/0    00:05:17 m4_proxy

sudo killall m4_proxy

sudo ./proxy

```
