About KW40Z Bootloader, currently only available OTA Bootloader function.
Can you provide KW40Z I2C Bootloader function and UART Bootloader.
Customers need to have these two functions.
I want to use the previous IC (KL25) to change code, but it in the Code Warrier or KDS,
Currently KW40Z in IAR, to cross a different environment, the difference is too big,
I can not find a method to start.
Hello Daniel Tseng:
For UART bootloader, you might find the next document useful, the software package includes an IAR project:
Kinetis Bootloader to Update Multiple Devices in a Network - for Cortex-M0+
As for I2C, there is only available the application note AN4655 with the corresponding software package AN4655SW which includes an IAR project:

Such I2C bootloader is actually a UART-to-I2C bridge to be used with the AN2295 UART bootloader PC tool:
