The K22F bootloader is pre-loaded into the flash of the chip. Is it possible to restore the bootloader in the event that programming the application firmware fails? If so, how does one go about doing that?
Hi Sabine Schnabeltier,
The K22F bootloader can be found from the KBOOT2.0, you can download KBOOT2.0 from this link:
After you download it, you can find the bootloader code from folder:
NXP_Kinetis_Bootloader_2_0_0\NXP_Kinetis_Bootloader_2_0_0\targets
Just use the debugger or programmer download the bootloader code to your chip.
Wish it helps you!
Have a great day,
Kerry
