KEA 128 Boot loader

irmantasbudrys — Fri, 30 Dec 2016 21:30:05 GMT

Hello All,

I am using FRDM DEV BRD KEAZ and S32DS. I need boot loader examples (using I2C, SPI, UART, CAN etc). I found KBOOT, but as I understand it doesn't support KEA devices. Where can I found any examples?

Best Regards,

Irmantas

Hi Irmantas Budrys,

1. I2C bootloader

Refer to KE application note AN4775:

http://cache.nxp.com/assets/documents/data/en/application-notes/AN4775.pdf?fsrch=1&sr=4&pageNum=1

According software:

http://cache.nxp.com/assets/documents/data/en/application-notes-software/AN4775SW.zip

2, UART bootloader

Refer to KE application note AN4767:

http://cache.nxp.com/assets/documents/data/en/application-notes/AN4767.pdf?fsrch=1&sr=3&pageNum=1

According software:

http://cache.nxp.com/assets/documents/data/en/application-notes-software/AN4767SW.zip

3. CAN bootloader

KEA128 CAN Bootloader

Based on the KDS IDE, you can port it to your S32DS

spi bootloader, we still don't have it.

Wish it helps you!

Have a great day,
Kerry

OK. Thanks for that.

What are differences between KE and KEA micros?

Is where any manuals how migrate from KE to KEA?

Best Regards,

Hi Irmantas Budrys,

KE is the 5V, Robust Microcontrollers (MCUs) based on ARM, it mainly used in the industry area. It is designed to maintain high-reliability and robustness in harsh electrical noise environments targeting white goods and industrial applications.

KEA is also 5V, Ultra-Reliable KEA Automotive Microcontrollers, it is targeted for a wide range of automotive and industrial applications requiring the highest level of quality and longevity support.

KEA have more wide temperature range, to meet the automotive demand. It also add some other module's like PWT which is not in the KE series.

But the communication interface is nearlly the same, so you can refer to the KE series.

There still don't have any manuals to migrate from KE to KEA, you can use the KEA project, and just add the according module code to the KEA. Then take care of the clock.

Wish it helps you!

Have a great day,
Kerry

Downloaded UART Bootloader. I don't understand where is the code. I expect when you go to src file to find .c files. But where are more projects and it is not clear for which one is for Bootloader application?

Best Regards,

Hi Irmantas Budrys,

UART Bootloader code:

AN4767SW\bootloader_uart\build\iar\Bootloader_sci

The according application code:

AN4767SW\bootloader_uart\build\iar\Blink_use_bootloader

Wish it helps you!

Hi Kerry Zhou,

The links you provided can't visited now. Where can i found these, especially I2C and UART examples?

Hi Yifeng Xie.

If you find the link is invalid, you can try to search it in the www.nxp.com directly with the AN number,

I2C Boot Loader Design on Kinetis E Series

Because this post is really very old,then the link in the NXP web may be changed, but it doesn't matter, you totally can search it in the NXP web.

BTW, if you have the new questions, please create the new question post for your own, then we will help you in your own question post.

Have a great day,
Kerry
