Hi I am trying to read a I2C slave device using PE SDK and MQX-lite. This would seemingly be easy. Even with very little, or more correct no code written by me, the program crashes. Here is what I have done:
-Installed Kinetis Design Studio 3.0.0
-Installed PE SW updates to add support for the MKL27Zxxx family
-Installed Kinetis Software Development Kit 1.3.0
-Run “Install new Software …” from PE to add SDK into PE (C:\Freescale\KSDK_1.3.0\tools\eclipse_update\KSDK_1.3.0_Eclipse_Update.zip)
-Add one output I/O pin. This pin will be used to drive a single LED
-Add OS to the project (MQX lite)
-Add one task and writing a few lines of code for blinking the LED once every second
This works fine and the LED is blinking.
Then I modify the program by adding one I2C master and enable Auto Initialization. I do not add any code to use the I2C master yet.
I recompile the code and start debugging the program. The program crashes and it seems like there are problems during task scheduling. Please note that I have not written any code myself for I2C initialization or usage. All code related to I2C are auto generated based on my settings in PE.
I actually do not think this has anything to do with I2C. It just happens to be I2C that’s the first interrupt driven driver that I am using in my first SDK+PE+MQX-lite project. I believe that the problem are somehow related to interrupts and MQX-lite.
Is there anything that I have forgot during setup that can explain this?
