Kinetis Updater KL27 Primer

philhale — Mon, 29 Jun 2015 20:26:46 GMT

I have downloaded Freescale Kinetis Updater / Bootloader V1.1.0 with hopes to modify this application as an updater to my board using a MKL27Z256VFM4. I want to have the opportunity to use this application to update firmware using USB or RS232/UART.

I have read all of the documents that came with V1.1.0 but there is little information (that I could find) that explain how to change the target processor. It isn't clear to me anyway.

Can you offer any guidance in this pursuit?

Thank you.

Phil

Hello Phil

I am not sure what application you are wanting to modify? The PC application (KinetisUpdater), the bootloader itself (on the KL27) or the application to load with the bootloader.

However, KinetisUpdater is not target specific because the target reports all details needed to it so that it can operate.

If you are developing a bootloader version for your own KL27 you can in fact get ready developed ones from

http://www.utasker.com/kinetis/FRDM-KL27Z.html

which includes KBOOT UART, KBOOT USB, USB-MSD (composite with KBOOT USB), SREC UART, SD card, "HIDloader.exe" USB, AN2295 Freescale Developer's Serial Bootloader loading for almost any Kinetis and IDE.

I want to modify the PC application itself.

I looked at the uTasker website yesterday but it wasn't very clear how much added development I would need to perform. I am an old software engineer with a lot of c experience but very little OOP/C++ experience. Since my Freescale processor already has the bootloader ROM, it seemed easy to modify the Kinetis Uploader app, especially if it already supports a USB interface.

I look forward to and appreciate your response and advice.

Phil

If you want to work with the inbuild ROM loader I don't think that you need to modify the PC application in any way (as long as the ROM loader is KBOOT conform).
