How to implement mke15z bootloader

[加奖张]

Expert:

Hello!This is the first time for me to use mke15z MCU, and the platform I used is expresso.Now I have a very urgent project, which needs to implement the function of bootloader. The specific requirements are: the interface of the controller prompts the customer whether to update the application program?If so, the update is sent via bluetooth.

Since I was the first time to learn bootloader, I found a lot of materials on the Internet, but I felt very scattered. I did not know which one should be my key point to learn. For example, the materials on my hand are as follows (etc.) :

1.Kinetis KE1xZ sub-family Reference Manual

2.MCU Bootloader v2.5.0 Reference Manual

3. The Document Number: AN2295

4. SDK_2. 5.0 _MKL82Z128xxx7

But after watching it once or twice, I still felt clueless and didn't know whether the direction of learning was right or wrong.I would like to ask the expert, can you tell me which one to learn in the first step, which one to learn in the second step and what to look at in the end? I hope there is a complete process to implement bootloader.

Bootloader implementation is mainly to learn ROM bootloader and flash-resident bootloader. I am a novice, how to achieve this function in a short time, I hope you can help me, thank you very much!

Hi jiajiang zhang,

First of all, I recommend you to download the proper SDK for your device. You can download it from the following link:

https://mcuxpresso.nxp.com

Also, it would be a good idea to read KE1xZ reference manual in chapter 22. Here the document explains the features and functionality of KE1xZ bootloader,

Once you have done that give it a check to the following demo application, I think it would be useful for your application.

MCU Bootloader Demo Applications User's Guide

I hope this helps.

Best regards,

Felipe

Hi jiajiang,

I recommend you to download the SDK for your specific device in https://mcuxpresso.nxp.com 

After that you can import the projects using the following document as guidance.

Importing an MCUXpresso SDK into MCUXpresso IDE 

Unfortunately we don't have a bootloader demo for the KE1XZ already implemented but you can port it as you mentioned in MCU Bootloader v2.5.0 Reference Manual Chapter 10: MCU bootloader porting.

Have a great day,
Felipe

For example, the basic question is which model of MCU SDK package should I download and port to MKE15Z

Hi

There are 'off-the-shelf' serial loaders and AN2295 port for the KE15Z at http://www.utasker.com/kinetis/FRDM-KE15Z.html if you need a fast solution.
See also http://www.utasker.com/docs/uTasker/uTaskerSerialLoader.pdf
and http://www.utasker.com/docs/uTasker/uTasker_BM_Loader.pdf
for another alternative.

Most free on GitHub (see uTasker project) or supported versions for professional needs.
