# Introduction
|
||
|
|
||
|
This is vanilla firmware option for the
|
||
|
[sumorobot platform](https://wiki.k-space.ee/en/projects/robots/sumo)
|
||
|
we use at K-SPACE.
|
||
|
|
||
|
The goal of this firmware option is to NOT get WiFi, Bluetooth or remote
|
||
|
programming in the picture and simply let the user program sumorobot
|
||
|
using favourite text editor or IDE and to upload the firmware via USB cable.
|
||
|
|
||
|
|
||
|
# Preparation
|
||
|
|
||
|
On Ubuntu make sure your user can access serial port.
|
||
|
If necessary run following, log out and and log into your desktop session again:
|
||
|
|
||
|
```
|
||
|
gpasswd -a $USER dialout
|
||
|
```
|
||
|
|
||
|
The firmware is flashed via USB cable. No need to press buttons on the robot.
|
||
|
The servo motors might interfere in some corner cases so USB connectivity is
|
||
|
not particularly reliable, just try to run `esptool.py` again.
|
||
|
|
||
|
|
||
|
# Bulk deployment
|
||
|
|
||
|
To build self-contained firmware image for ESP32 use, eg when you need to flash
|
||
|
multiple robots easily:
|
||
|
|
||
|
```
|
||
|
docker run --rm -v $PWD/modules:/src/ports/esp32/modules -v $PWD/build:/build harbor.k-space.ee/k-space/micropython-esp32
|
||
|
```
|
||
|
|
||
|
To flash the built binary:
|
||
|
|
||
|
```
|
||
|
esptool.py -p /dev/ttyUSB0 --chip esp32 -b 460800 write_flash -z 0x1000 firmware.bin
|
||
|
```
|
||
|
|
||
|
To open up serial console:
|
||
|
|
||
|
```
|
||
|
picocom -b115200 /dev/ttyUSB0
|
||
|
```
