secondary bootloader for K32L2B31VLHOA

[plefebvre]

Hi

who knows how to create a new bootloader with user's flash application on K32L2B31VLHOA

allowing the on-chip flash memory to be programmed or erased

I cannot use the boot rom bootloader provided on the chip because i use a lpuart half duplex rs485 communication 

many thanks for help

Hi Pierre,

please use flash bootloader. You can download the flash bootloader from MCU Bootloader | NXP 

https://www.nxp.com/webapp/Download?colCode=NXP_KINETIS_BOOTLOADER_2_0_0&appType=license 

There isn't K32L2B in this package. You have to migrate KL25's project to K32L2B.

Regards,
