# How to compile the rnode firmware yourself
|
||
|
|
||
|
## Dependencies
|
||
|
|
||
|
Make sure 'git', 'make', 'python' and 'pip' are instaled. Most like;y these are already availble on your system. Otherwise do:
|
||
|
|
||
|
$ sudo apt install git
|
||
|
$ sudo apt install make
|
||
|
$ sudo apt install pip
|
||
|
$ sudo apt install python
|
||
|
|
||
|
Download arduino-cli
|
||
|
|
||
|
$ cd
|
||
|
$ curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh
|
||
|
|
||
|
Add arduino-cli to path by editing ~/.bashrc
|
||
|
|
||
|
$ nano ~/.bashrc
|
||
|
|
||
|
add 'export PATH=~/bin:$PATH' to end of file
|
||
|
|
||
|
## Clone git repo
|
||
|
|
||
|
$ git clone https://github.com/liberatedsystems/RNode_Firmware_CE.git
|
||
|
|
||
|
## Prepare
|
||
|
|
||
|
Install the required BSP and libraries for the ESP32 system.
|
||
|
|
||
|
$ cd RNode_Firmware_CE/
|
||
|
$ make prep-esp32
|
||
|
|
||
|
This command stalled. I stopped the command by hiting CTRL-C and restarted it.
|
||
|
|
||
|
Add rns software to path:
|
||
|
|
||
|
$ nano ~/.bashrc
|
||
|
|
||
|
add 'export PATH=~/.local/bin:$PATH' to the end of the file.
|
||
|
|
||
|
## Test
|
||
|
|
||
|
To test if you can compile the firmware try it:
|
||
|
|
||
|
$ make firmware-heltec32_v3
|
||
|
|
||
|
Fingers crossed!
|
||
|
|
||
|
## Define new board, the theory
|
||
|
|
||
|
In order to build custom firmware for a new board it has to be defined in several files.
|
||
|
|
||
|
### Makefile
|
||
|
|
||
|
BOARD_MODEL defines the target board. It is a unique 8 bit number.
|
||
|
BOARD_VARIANT defines the variant of the board. A board could come with different LoRa transceivers, for example. It is also a unique 8 bit number.
|
||
|
|
||
|
Every target board has a section 'firmware-<board_name>', 'upload-<board-name>' and 'release-<board-name>'
|
||
|
|
||
|
### boards.h
|
||
|
|
||
|
Both BOARD_MODEL and BOARD_VARIANT are #defines in this file. They are used to define the pinout of the SPI port and if it has certain perifirals such as a screen BLE etc.
|
||
|
|
||
|
Let's see an example:
|
||
|
|
||
|
#elif BOARD_MODEL == BOARD_HELTEC32_V3
|
||
|
#define IS_ESP32S3 true
|
||
|
#define HAS_DISPLAY true
|
||
|
#define DISPLAY OLED
|
||
|
#define HAS_BLUETOOTH false
|
||
|
#define HAS_BLE true
|
||
|
#define HAS_PMU true
|
||
|
#define HAS_CONSOLE true
|
||
|
#define HAS_EEPROM true
|
||
|
#define HAS_INPUT true
|
||
|
#define HAS_SLEEP true
|
||
|
#define PIN_WAKEUP GPIO_NUM_0
|
||
|
#define WAKEUP_LEVEL 0
|
||
|
#define INTERFACE_COUNT 1
|
||
|
#define OCP_TUNED 0x38
|
||
|
|
||
|
const int pin_btn_usr1 = 0;
|
||
|
|
||
|
#if defined(EXTERNAL_LEDS)
|
||
|
const int pin_led_rx = 13;
|
||
|
const int pin_led_tx = 14;
|
||
|
#else
|
||
|
const int pin_led_rx = 35;
|
||
|
const int pin_led_tx = 35;
|
||
|
#endif
|
||
|
|
||
|
const uint8_t interfaces[INTERFACE_COUNT] = {SX1262};
|
||
|
const bool interface_cfg[INTERFACE_COUNT][3] = {
|
||
|
// SX1262
|
||
|
{
|
||
|
true, // DEFAULT_SPI
|
||
|
true, // HAS_TCXO
|
||
|
true // DIO2_AS_RF_SWITCH
|
||
|
},
|
||
|
};
|
||
|
const int8_t interface_pins[INTERFACE_COUNT][10] = {
|
||
|
// SX1262
|
||
|
{
|
||
|
8, // pin_ss
|
||
|
9, // pin_sclk
|
||
|
10, // pin_mosi
|
||
|
11, // pin_miso
|
||
|
13, // pin_busy
|
||
|
14, // pin_dio
|
||
|
12, // pin_reset
|
||
|
-1, // pin_txen
|
||
|
-1, // pin_rxen
|
||
|
-1 // pin_tcxo_enable
|
||
|
}
|
||
|
};
|
||
|
|
||
|
If we want to add support for a new board we have to add a new section for this board. Here we define all the features it has or not has.
|
||
|
|
||
|
## Define new board for real
|
||
|
|
||
|
Let's say we want to add support for the Waveshare ESP32-S3 Pico with an SX1278 LoRa transceiver. First we have to make define both BOARD_MODEL and BOARD_VARIANT. Let's define BOARD_MODEL as 0x61 and BOARD_VARIANT as 0x31 as these numbers are not used yet. Here the 0x31 indicates the use of a SX1278 LoRa transceiver. In the future we can define more transceivers for this board. Then we make entries in the Makefile.

|

|

Also, in the file Utilities.h add entry. Again, within the '#if MCU_VARIANT == MCU_ESP32'.
|
||
|
|
||
|
#elif BOARD_MODEL == BOARD_LORA32_V2_1
|
||
|
void led_rx_on() { digitalWrite(pin_led_rx, HIGH); }
|
||
|
void led_rx_off() { digitalWrite(pin_led_rx, LOW); }
|
||
|
void led_tx_on() { digitalWrite(pin_led_tx, HIGH); }
|
||
|
void led_tx_off() { digitalWrite(pin_led_tx, LOW); }
|
||
|
void led_id_on() { }
|
||
|
void led_id_off() { }
|
||
|
|
||
|
### Flashing the board
|
||
|
|
||
|
Make shure you are in the dialout group. If not:
|
||
|
|
||
|
$ sudo usermod -aG dialout <username>
|
||
|
|
||
|
If you are flashing a custom board, you will need to generate a signing key in rnodeconf prior to flashing if you do not already have one by running:
|
||
|
|
||
|
$ rnodeconf -k
|
||
|
|
||
|
Than flash the firmware.
|
||
|
|
||
|
$ make upload-waveshare-esp32-s3-pico
|
||
|
|
||
|
This will end with error 'This device has not been provisioned yet, cannot set firmware hash'. But fear not. After flashing a custom board, you will also need to provision the EEPROM before use:
|
||
|
|
||
|
$ rnodeconf /dev/ttyACM0 -r --platform ESP32 --model a4 --product f0 --hwrev 3
|
||
|
|
||
|
### Migrating to a other system
|
||
|
|
||
|
When the rnode is flashed, it is signed with a key. If you conect the rnode to another system, this key cannot be validated. It is possible to write a new key to the rnode by erasing the eeprom and writing the local key to it.
|
||
|
|
||
|
$ rnodeconf /dev/ttyACM0 --eeprom-wipe
|
||
|
$ rnodeconf /dev/ttyACM0 -r --platform ESP32 --model a9 --product f0 --hwrev 3
|
