Using i2c and uart freeRTOS

[songja]

Hello,

I have tried to include both i2c and UART freeRTOS to send data out thru UART.

But as soon as I include UART freeRTOS, it throws errors as below.

I have tried the example code for k66f, "frdmk66f_freertos_i2c". simply by just adding the uart rtos driver and it failed to compile. But when I created a new project then tried the same without any code from the example, it worked.

So I assume that it must be something to do with the code?

Is there any other way to implement both i2c and uart on RTOS?

Thank you in advance.

Hi

Please also refer to below link for the memory management in FreeRTOS

FreeRTOS - Memory management options for the FreeRTOS small footprint, professional grade, real time...

Hi

This looks like a configuration problem - there are a number of heap strategies and you need to define which one you want to use. Presently all are enabled and so the same subroutine is present a number of times so it will fail to link. Check what controls each and disable the ones that you don't want to use.
