I know the KL25 series support SWD Debug but I can't make sure if it support ISP or IAP download.
Solved! Go to Solution.
Obviously, you have to develop ISP/IAP according to FSL's application note for bootloader. So far you can find following reference designs from FSL.
The bootloader takes some user code space. Furthermore, user code has move its ISR to RAM. I prefer FSL can follows NXP's implementation, which has on board ISP, and it is separated from user space.

Hi Kai Liu,
Can you give me some tips how to run USB bootloader on KL25z? You wrote that you have ported AN4370 application note. Maybe can you share your project?

Just FYI,
I am still stuck on serial bootloader now, I put USB MSD bootloader after that. So I can not offer anything at this moment. Sorry.
