Bootloader for Kinetis KV31 MCU

Hello, 

I need to update my KV31 MCU using the bootloader. Searching on the community I found the Bootloader 2.0.0 for the KV31, and downloaded the bootloader. 

Are there any documents on how to modify this bootloader to work for my hardware? Are there any particular aspects of the bootloader I would need to modify for my hardware? I know I need to change the bootloader to take in the file to be loaded through SPI. 

Thanks for the help

Hi,

Did you mean that you do not use a tower board but your own customer board? For this case, maybe you would like to change the UART port. See this document on how to change the uart port:

How to change UART port on MCU Bootloader2.0.0 

Also here is an overall guideline of the bootloader solution for Kinetis MCUs for your reference:

Thanks Fang, I do mean I want to use my own board, and I want to change the UART port. I will take a look at this
