Building

Clone:

mkdir -p ~/go/src/3mdeb && cd ~/go/src/3mdeb
git clone git@github.com:3mdeb/RteCtrl.git
cd RteCtrl

if $GOPATH is set, change ~/go to $GOPATH

For host system:
```
make
```
For arm system:
```
make build-arm
```
For amd64 system:
```
make build-amd64
```

Installation

Install RteCtrl binary to $PATH
Install config/RteCtrl.cfg to /etc/RteCtrl/RteCtrl.cfg
Install web directory to path pointed in RteCtrl.cfg:
```
"web_directory" : "web",
```
Adjust path to flashrom in RteCtrl.cfg if necessary:
```
"flashrom_bin" : "/usr/local/sbin/flashrom",
```

Usage

Required connection:

connect DUT's power button pin to J11 header pin 9 (GPIO header with OC buffers)
connect DUT's reset pin to J11 pin 8 (GPIO header with OC buffers)
connect DUT's power supply to RTE J13 connector
connect RTE J12 connector with DUT's DC connector via DC Jack - DC Jack wire
(only for flashing procedure) connect DUT's SPI header with RTE J7 SPI header

Open in browser: <RTE_IP>:8000

Buttons responsible for power control:

Power ON  - sends a pulse on power button pin to power on DUT
Power OFF - ground power button pin on DUT to force it into ACPI S5 state
Reset     - send a pulse on reset pin on DUT
Relay     - toggles the RTE relay on/off deriving the power to DUT

Buttons responsible for flashing firmware:

Browse... - browse for file to flash DUT's firmware
Upload    - uploads chosen file to RTE (required)
Flash     - starts flashing firmware process
