Using NetBeans and Gnu ARM tools, I was able to build and run the ChibiOS/RT demos for the STM32F4 discovery board. I downloaded the zip file containing the latest version of ChibiOS/RT and extracted it to my NetBeansProjects folder. To build a project:
- File -> New Project -> C/C++ -> C/C++ Project with Existing Sources
- Browse to the appropriate directory e.g:
- Select Tool Collection as GNU ARM
- Select Automatic Configuration Mode
That’s it, the project is imported and automatically builds! You can load it onto the target using st-flash and debug it (if desired) using st-util:
- st-flash write \Users\dalbert\Documents\NetBeansProjects\ChibiOS_2.6.7\demos\ARMCM4-STM32F407-DISCOVERY\build\ch.bin 0x8000000
- st-util (make sure you’ve configured build/ch.elf as the project Properties->Build->Make->Build Result)
I’ve built and tested the three STM32F4-DISCOVERY demos and they all ran successfully including the VCP USB comm port with command interpreter in the MEMS demo.
I’ve also built the ChibiOS/RT + lwIP + PPP application here which required a few fixes and must be linked with ChibiOS/RT 3.x but then runs nicely using the serial port (PA2, PA3) to serve a PPP connection. I have two directories under NetBeansProjects:
Then I create a symlink under stm32f4-chibi-…-master/lib called ChibiOS-RT that links to ../../ChibiOS_3.0.x.
On the remote terminal (linux box) side, I configured /etc/ppp/options including the serial port I was connected to (/dev/ttyUSB0) and the baudrate (38400); the whole file looks like this:
# Prevent pppd from forking into the background
# wait for connection if none initially found
# no hardware flow control
# don’t use modem control lines
# create a default route for this connection in the routing table
# no authorization required
# ensure exclusive access to the serial device
# do not set up any escaped control sequences
# use a maximum transmission packet size of 552 bytes
# use a maximum receive packet size of 552 bytes
# IP stack configuration
Launch pppd specifying localip:remoteip: which generate the ppp0 network interface (shows on ifconfig):
sudo pppd 172.30.1.98:172.30.1.99
Reset the discovery board and the PPP connection is up! You can ping the discovery board (ping 172.30.1.99) and can bring up a remote shell connection using netcat: nc 172.30.1.99 25 (note to send a CR requires Ctrl-V <enter><enter>).
