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
please use flash bootloader. You can download the flash bootloader from MCU Bootloader | NXP
There isn't K32L2B in this package. You have to migrate KL25's project to K32L2B.
