The Raspberry Pi is an awesome $35 dollar Linux board containing a Broadcom system on chip that integrates a 700MHz ARM11 CPU core, a very powerful GPU capable of running 1080p graphics as well as 256MBs of RAM. The Board provides two USB ports, an Ethernet port, an HDMI port as well as a 2×13 0.1″ header providing access to GPIO/I2C and SPI peripherals! for more on the Raspberry Pi board please visit: http://www.raspberrypi.org/

I will be writing a series of tutorials on developing for the Raspberry Pi in C++. In order to follow through with this tutorial you will need to have good familiarity with C/C++ and to also be somewhat familiar with Linux. The tutorial series will include the following topics:
- Setting up a Kubuntu virtual machine using VMware Player
- Installing Raspbian on the Raspberry Pi
- Development Environment for the Raspberry Pi using a Cross Compiling Toolchain
- Introduction to accessing the Raspberry Pi’s GPIO in C++ (Linux Way!)
- Remote debugging of your application while its running on the RaspberryPi (GDBServer)
- Interfacing an I2C GPIO expander (MCP23017) to the Raspberry Pi using C++
- Writing SPI application
Hi!
How is installment of episode 5 “Remote debugging of your application while its running on the RaspberryPi ” coming along?
I had great success with setting up my development environment following your directions but it has been and continues to be a struggle to get the remote debugging working. It would be nice if you were working on this installment
Thanks
Kyle,
Traditionally I was planning to write it up in Early December (Waiting until I get my New 512 MB RPi). But since there’s interest on this topic I will try to have it comppleted by this weekend!
This is great news!
The trouble I have is with properly configuring eclipse to do the remote debugging. Which actual gdb to use within eclipse is a question (I have attempted a few). The connection setup within the debugging configuration also seems obvious as to what is required. However it never seems to work as eclipse complains that the “Program is not a recognized executable.” I can only assume it is referring to gdb, the other possibility could be the HelloWorld but I doubt it. The thing is that it is not clear how to actually see what eclipse is trying to do when it starts the debugging effort – if there was an output console or log to look at at see what actual tool (i.e. gdb) eclipse is trying to utilize would be a help. Maybe if you run into this same problem you could comment about how you were able to diagnose and solve this mystery. I am supplying this information here just as a point of reference for you.
Thanks for your efforts on your tutorials here they are very nice and well done.
Kyle I’d imagine that you need to get Eclipse to utilize the toolchain’s “arm-linux-gnueabihf-gdb” gdb client (not Kubuntu’s/ Ubuntu’s native GDB Client!!!!) and have that connected to a gdb-server (You’d have to install the gdb-server package on the RPi) running on the Raspberry Pi. The other way that you could go is to integrate the “gdb-multiarch” GDB client in Eclipse. I will test both approaches. Details will be forthcoming
