ChibiOS Free Embedded RTOS

Has anybody improved the Integration of lpc11c24 meanwhile ?
I am currently starting to use Olimex LPC-P11c24 board with Chibios and want to utilize CAN Interface.

Thanks

Well the main difference was the optimization settings for te compiler -O0 is ok but -O2 doesn't work. Some I will have a look at the generated code....

Ahhhhhhhhh, finally I found my mistake...
the APB1 Divider somehow was set at 16, at 4 everything is OK.
Arrrrrrrrrggghg..

If I insert waits between the toggles it works, but its much slower compared to doing it without the ChibiOS. It must be something with the clock setup, prescalers or GPIO-config or flash-waitstate etc...

Thank You

I am using a STM32f407 Dicovery board here. I try to toggle a GPIO pin as fast as possible.

palClearPad(GPIOE, 15);
//mDelay(18);
palSetPad(GPIOE, 15);
//mDelay(18);

If I toggle without delay only random spikes can be seen. When I enable the delay I can see the pin changing states on the Oszi ...

Ok, this worked. Thanks. Next will be debugging

By the way. Is this the roadmap or are You still going on with ChibiStudio as well ?

I can see that STM32F4-Discovery.xml. When I generate a project it is copied to my workspace directory. However when I look under ChiboOS_RT STM32f4xx Board Component in the wizard i can read the following:

Board Identifier: GENERIC_STM32F4XX
Board name: Generic STM32F4xx

When I try to load the ...

Ok, I finally built my first working )(demo)-project in SPC5 Studio. The wizard creates a Generic STM32f4 board. Is there already a feature to select a predefined board ? I have a stm32f4discovery and an Olimex STM32-E407.

Thanks

Ah one step further. The green PLUS sign ......

Ok, thanks. Been there already, This opens the SPC5 Application Configuration. Under Application Content there are two options "Structure" and "Graph" but when I select "Structure" ->"Exported Features" I can only add components like "com.example.xyz0". Am I expected to type something here or should ...
