Firmware upgradation

[mayursavaj]

Hi,

I am working on Kinetics K22 series controller for firmware based application.

Currently We are upgrading device firmware through USB cable & DFU Demo(freescale) software.

Can we have any other method to upgrade the device firmware??

Can I upgrade firmware Wireless?

Thanks in advance.

Hello Mayur Savaj:

I think you are using a MK22FX512VLL12, correct?

What other method or interface do you want to use? By "wireless" you mean an interface such as Bluetooth or WiFi?

There are some application notes that come together with project examples for integrating bootloaders for Kinetis family. These are some:

- UART Bootloader (AN2295):

- USB MSD Host bootloader (AN4368):

- USB MSD Device bootloader (AN4379):

To find the software packages simply append SW to the appnote number (e.g. AN2295SW) and search in our Freescale website.

There is also the new KBOOT, but unfortunately your device is not supported, you would need to migrate it.

As for the wireless bootloader, we have no examples available, you would need an extra wireless connectivity interface to receive the new firmware and send it to K22. Freescale has some solutions, see this page:
