Can I Replace the ROM Image in a KL17 Processor?

Can I erase and replace the ROM image in a KL17 processor? We have our own bootloader that was developed in the early years of Kinetis production. We do not wish to change this bootloader. We are using an IAR I-Jet to load/debug code.

Thanks,

Wayne

Hi @waynewilburn ,

No, you can't. But you can skip the ROM bootloader by configuring FOPT[BOOTSRC_SEL]. Details please check in the reference manual. Then put your bootloader at the top of flash.
