USB Bootloader

Hi Guys,

 

We are using K60 series. Looking for a USB bootloader. If it is inbuilt, will it take care of USB driver as well or we have to drive the usb by some other means (OS or driver if we have access to bootloader source)?

If we need other OS to drive USB then is it worth to use a seperate OS just to drive USB or there is any other method where we can use USB bootloader for firmware upgradation?

If there is no inbuilt USB bootloader from where can I get it?

 

Please share your suggestions.

Hi KP,

 

USB bootloader is not built in.

 

You will need USB driver to driver the USB, for that you can use OS with support for USB, infact if you go for OS with USB booloader support you will get USB driver built in.

Hi KP,

 

There is application note for USB bootloader under

"Freescale.com>products>kinetis>K60>Documentation>Application notes" for USB boot loader.. The application note explains bare metal and MQX based USB Bootloader.
