I have been struggelig for a few days now, to get the STM3210E evaluation kit going with FreeRTOS.

I have downloaded the contributed port: [http://interactive.freertos.org/attachments/token/7ji4vw534mlvh1t/?name=FreeRTOS\_STM3210E\_EVAL\_with\_IAR\_5\_41\_2.zip](http://interactive.freertos.org/attachments/token/7ji4vw534mlvh1t/?name=FreeRTOS_STM3210E_EVAL_with_IAR_5_41_2.zip)

Trying to debug the port ends up in a “HardFault”. After disabling all the tasks except LEDFlash, things started working. LCD task can also be enabled, but enabling any more, results in a HardFault. Disabling LEDFlash and enabling CheckTask works well, but when both of them is enabled together with LCD, error occurs once again. I have tried to increase the stack and heap size in startup-file with no luck.

Does anyone have any pointers to what i can try next?

I cannot support contributed code, but have provided the following list of “usual suspects” in point three of the following page:

[http://www.freertos.org/FAQHelp.html](http://www.freertos.org/FAQHelp.html)

On an STM32, pay particular attention to the forth bullet point under point three, as unlike most CM3 vendor libraries, the STM32 libraries do not do this by default.

Regards.

I tried with different versions of the IAR compiler and works correctly with 5.41 and 5.50,  
while with 6.10 the port ends up in a “HardFault”.  
Just have a little free time I try to investigate.

Hi,

Update the demo for IAR 6.10 in FreeRTOS Intercative!

I hope it is useful
