I currently crawling through the docs of KBOOT (Kinetis Bootloader|NXP ).
For the first step, I don't want to use cryptography for the firmware download BUT I would like to have the firmware verified with a CRC.
My question basically is: What tool precalculates the CRC of my application binary and inserts this value into the BCA ?
Seems KinetisFlashTool is what I need:
could you please provide a cross platform tool to do this?
it would also be possible to do it using the srecord tool with the right sequence of commands. could you please provide any solution for osx/linux?
Unfortunately, I do not know about another tool that can help you to calculate your image's CRC value.
But as already said, you can try to use Kinetis Flash Tool which calculates this value automatically when a .bin file is provided.
I hope this helps!
