How to update the firmware of MK20DX128VLF5 using USB(pendrive)?

[vigneshkumarp]

Hi, We are using my own board of MK20DX128VLF5. Here we are copying the data(that was stored in flash) from controller to USB(pendrive) and it was done.

Now we need to update the firmware through USB(pendrive). Using code warrior10.6 the .S19 is generated and how can we use that .S19 file to reprogram the controller?  Or what is the procedure to update the firmware through USB(pendrive)?

And Sorry for the change in my questions. We changed the controller to MK22DX256VLF5 due to our requirement. And now we want to do the same for this controller to update the newer version of firmware through USB(pendrive).

Thanks.
