Bootloader in KW45

Can we build custom bootloader for KW45 ?

Can we program other MCU using KW45 (consider other MCU can be reprogrammed via its spi) , so here how can we give other MCU hexfile/firmware to KW45 . Please let us know if there is any Application note

Hello,

Could you help us explain more details about what you trying to achieve?

Are you using a KW45 EVK board? Or the KW45 in a custom board?

Could this Application note available for KW45 explain what you trying to achieve? Please refer to introduction section.

hI Luis,

Thanks for replying!

We are using KW45 EVK board . We want to program NTM88 MCU via spi of other MCU (this application note is there in NTM88 documentation https://community.nxp.com/pwmxy87654/attachments/pwmxy87654/sensors/8058/1/NTM88_SPI_Reprogramming_rev2.pdf). In our case other MCU is KW45 . So to program NTM88 through KW45 we need to take firmware of NTM88 inside kw45 first and then with spi we need to transfer it to NTM88 . This is what we want to achieve . Is it possible then how?

Hello,

The NTM88 is an old sensor; I would recommend redirect this question to Analog and Sensors Community to find more information regarding the NTM88.

Here is a Link for it Sensors - NXP Community

I really apologize for the inconveniences this might cause you and your project.

What you could review is this Application note that describes using NTM88 with a MCU Host, please check this guide to see if adjust to your necessities.
