Is there an IAP demo about MKE15Z256VLH7?

Hi
Thank you for your kindness.
I can't find any IAP demo to refer about MKE15Z256VLH7. How can I implement firmware update using MKE15Z256VLH7? Does anyone know?

Hi,

It seems you have to PORT an existing bootloader to it。See https://www.nxp.com/docs/en/reference-manual/MCUBOOTRM.pdf capture 10,there will help you port a bootloader and see https://www.nxp.com/docs/en/application-note/AN4367.pdf will help you port an Ethernet bootloader .

Hi,

MKE15Z256 have a rom bootloader on chip,you can use it .About ROM bootloader,see "Chapter 22 Kinetis ROM Bootloader" in KE1xZP100M72SF0.pdf on the nxp website.

1. The ROMbootloader must use UART or I2C or SPI. Ethernet is not supported. It is limited. I need a generic bootloader whose main function is to erase and write to flash, modify the vector and jump to the application.

2. According to different MCU support different boot methods, respectively:
Flash-resident bootloader (provided as source code).
Flashloader (Preprogrammed in device flash).
ROM bootloader (Preprogrammed in device ROM).
Secondary Bootloader.
now I use the MCU supports ROM bootloader, but it does not meet my requirements. Maybe Flash-resident bootloader is more suitable. Can I change the demo program of Flash-resident bootloader to MKE15Z256VLH7 ? If it can be achieved, what should I consider in the migration? Which MCU is similar to MKE15Z256VLH7, is there a corresponding demo program?

Hi

The uTasker project includes various secondary loaders for the KE15: http://www.utasker.com/docs/uTasker/uTaskerSerialLoader.pdf
