USB bootloader KL25Z

Is anyone on the Freescale team working on getting a USB bootloader running on the KL25Z? Something equivalent to one of the Kinetis bootloaders which can be used to update firmware over USB without the need for the K20 chip?

Question relating to:

Freescale is a leader in embedded processing solutions for the automotive, consumer, industrial and networking markets.

Hi,

this is something I wanted to do for a while as KL25Z is cheaper (at least the chips I have checked). I am personally not aware of an development there.

I believe if you start it and share with the community the effort ,somebody might join the effort.

I think I will first get the Kinetis HID bootloader working with an mbed application and then think about a MSD version. One thing I need to be able to do in my mbed application is to change the vector location using SCB->VTOR, but how do I make sure this is executed before any interrupts occur such as from constructors?
