STM32F4DISCOVERY
STM32F4DISCOVERY has STM32F407VGT6 microcontroller featuring 32-bit ARM®Cortex®-M4 with FPU core, 1-Mbyte Flash memory, 192-Kbyte RAM.
The board has integrated debugger that allows to program it with single USB-A-USB-mini-B wire. You can run and test Embox after a few quite simple steps.
- Configure and compile with
platform/stm32/f4/stm32f4-discoverytemplate. - Connect with OpenOCD:
$ sudo openocd -f /usr/share/openocd/scripts/board/stm32f4discovery.cfg
If it doesn't works (probably your stm32f4-discovery board is STM32F407G-DISK1):
$ sudo openocd -f /usr/share/openocd/scripts/board/stm32f429disc1.cfg
- Load Embox with usual gdb commands
$ arm-none-eabi-gdb build/base/bin/embox
(gdb) target remote :3333
(gdb) monitor halt
(gdb) load
(gdb) monitor reset
You can refer our How-to-flash guide for more details.
We are using an extension board with this board. It will allow you to try more stuff with Embox, e.g. networking.
To start using Embox, you can just plug serial cable into your STM32F4DISCOVERY board and your PC and flash Embox as described above. Now you are able to connect with minicom:
sudo minicom -D /dev/ttyUSB0
As for any other template in Embox, you are able to use POSIX libraries, e.g. pthreads. You can refer to our Quick Start guide to get started with development under Embox.
You are able to use ping, telnetd and httpd with this template. Just plug in Ethernet cable in the base board and your PC. You can also edit conf/start_script.inc and re-build Embox to set up another IP address of the board if required.
We have ported PJSIP to Embox. Read more about PJSIP and audio playing/recording here.
You can try an example of a simple robot with light and IR sensors, motors and NRF24 radio module. Template platform/stm32f4_multibots/nrf24.
