2. Good job man! Keep working. Try to put in list how to show messages via ITM Stimulus port by using ETM in ARM Cortex MCU. Such a plugin is only available DS5 Professional from ARM which is quite expensive.

3. regarding makefiles – check out https://github.com/dmoulding/boilermake
   i used it to create multiple-architecture, cross-compiling makefiles for the OMAP processor that ran within Eclipse (so I could compile a project with bits of x86, bits of ARM, and bits of TI DSP C)… hacked his scripts a bit, and I see that now the author added some of my hacks allowing cross compilation (e.g. TGT_CXXFLAGS, though he missed TGT_AR).
   it does the dependencies automatically and is pretty great in traversing a hierarchy of makefiles as well. I had auditioned a few and considered writing my own, this one was my favorite.

4. Hi Erich

   The blog on the Burner was verry helpful. Is there anyway to get CW 10.4 to download a binary file from Burner.exe? I can generate the file but can’t see how to load it over the PE multi-link. I know the binary can be used for external programmers, but I only have the multi-link for the Kinetis.

9. Hi,
   I’ve been using your FreeRTOS bean with a 9S12XDP512 uC and the code works very well in the banked memory mode. I’m curious if the bean is aware of and able to use the other RAM pages and not just the banked flash space.

   • Hi Mark,
     good to hear the usage of FreeRTOS for the DP512, I have not used that core for a while. There is no special things in FreeRTOS for S12 for now as far as I can tell for code banking: the linker will distribute the functions across pages. I guess you are interested mostly in placing the heap into special memory bank? I have added something like this for Kinetis (https://mcuoneclipse.com/2013/07/10/freertos-heap-with-segmented-kinetis-k-sram/), but not for S12.

    I’m just starting a project using Processor Expert. Its going fairly well but I would like to create a new component that will create a Interrupt Handler wrapper for the Software Interrupt (SWI).

      is this for Kinetis/ARM? You might have a look at the nRF24L01 component I have created on GitHub (https://github.com/ErichStyger/McuOnEclipse_PEx/tree/master/Beans/nRF24L01): this uses the ExtInt interrupt.
      Otherwise for ARM you could directly hook into the the SWI interrupt vector. Have a look at my FreeRTOS (https://github.com/ErichStyger/McuOnEclipse_PEx/tree/master/Beans/FreeRTOS) component where I directly allocate the software interrupt vector. And you could use this example to if you do this for other cores: in the FreeRTOS I need to hook into the SWI too.
      I hope this helps.

    • Hi Peter,
      Clearly, the Kinetis SDK is not something for the highest performance. Because it adds all the layers in between, with function calls. So you could either do directly from your application the pin writing (access directly the registers). Or you could change the SDK code (e.g. removing the asserts, do the inlining yourself). As always, you need to balance portability, easy-to-re-use, nice software API’s vs. speed and code size.
      I hope this helps.

20. Hi Erich,

    currently, I’m doing some benchmarking on the flash execution performance of several microcontrollers.
    The kinetis k65 compares very bad in contrast to an stm32f429 both clocked at 180 MHz and all possible caching options enabled. Meaning it degrades to ~60% performance due to flash wait states.

    have you done similar research? are you aware of any tricks in the kinetis k65/k66 family which could speed up execution from internal flash?

    Also a hard to find utility not mentioned much online/hard to find, still useful, and how to run it. I think you can create a batch file that runs the program and drag a file on the batch to open or called to run via eclipse. Like i said, not much info online, but great tool. Seen it works on mac, but never took the time yet to create batch file to test it on windows. (should work on windows too)
