[New] Side project: ChibiToolchain

[noether]

Do you still have problems with OpenOCD and STLINKv1/2 ?

It seems that a new release candidate is out and they claim that it supports STLink, actually there is a .cfg specially for the discovery board.

Hi,

I am using the RC1 too on Linux without problems, very fast and stable with both ST-Link V1 and V2 (even if you have to configure USB stuff and this is a bit complex, probably I should add a specific guide about this).

I still have to try it on Windows using that pass-through driver, if it works I will assemble a new ChibiStudio with the latest components.

0.6 is now officially released and supports STlink1/2

The list of changes is on the website.

Nice, official Cortex-M4 support.

I am using ST-Link v1 and v2 under both Windows and Linux using 0.6.0, no problems so far. The setup under Linux is a bit complicated because permissions etc, probably I should add a guide.

Hi Giovanni, very nice work! I have been 'struggling' for months to start something with my STM32F4 discovery board due to the needed setup for the tools (and not enough free time to do it also), and in a few minutes I have a working system using ChibiStudio. I had it working already with CooCox but it was much easier to make it work with the ChibiStudio
One thing I didn't find in the forum or documentation was how to create a new project, what should be the best aproach for example to create a new project for the STM32F4 discovery board? Can you give me some clue of how to do it?

Hi,

The current way is to clone an existing project, remove in .project and .cproject files, then import it using the procedure described here: http://www.chibios.org/dokuwiki/doku.ph ... to_eclipse

I am working on an Eclipse plugin that will allow to create easily new projects, it will go in future ChibiStudio versions.

Thanks for your super fast reply. After importing the project it didn't apear on the project explorer, but if I try to import it again it says it already exists (overlaps the location of another project), do you know what did I make wrong? Thanks!

[Giovanni]

The project is imported but you have to associate it to a working set, select "Properties" on one of the working sets you see in the left panel or create your own working set.

Hi giovanni, thanks again for your help, it worked. Now I'm having a problem using the STM32F4 Discovery board, I can use it in this windows 7 64 bits PC with the ST tools and with CooCox but it was not working with ChibiStudio. After some atemps to try to solve this issue I found that if I run the openocd binary manually then I can use the debugger in ChibiStudio. I'm running it like that, in a console:

C:\ChibiStudio\tools\openocd>bin\openocd-0.6.0-rc2.exe -f interface/stlink-v2.cfg -f target/stm32f4x_stlink.cfg

Is this the correct way of doing it (starting manually openocd in a console), or am I doing something wrong?
