Hi Senthilprabhu

Various boot loaders are readily available for immediate use on the KV31F - see
- http://www.utasker.com/kinetis/FRDM-KV31F.html
- http://www.utasker.com/kinetis/TWR-KV31F120M.html

These are proven and documented: Serial Loader: http://www.utasker.com/docs/uTasker/uTaskerSerialLoader.pdf
and can be build/customised with MCUXpresso, KDS, S32 Design Studio, CW 10.x, IAR, Keil, CooCox, Green Hills, Rowley Crossworks, Atollic, GCC make file or VisualStudio.

Hi Senthilprabhu G

Sorry did you get the bootloader, I'm starting to work with this MCU but I have the same problem. I have check examples downloading SDK with SDK builder but there is no examples for MKV31F128xxx10. Just for MKV31F512xxx12. Could you help me? If you can't share your code, cold you guide me in how to get it? Right now I need to know If has to set an especific configuration of pins for the PCB design to get a bootloader by I2C and UART. Thanks a lot:

Best Regards

Hi Oscar Nino,

There is no example code for MKV31F129xx10. Use MKV31F512xxxx to get the example codes. But there is also no example codes for Bootloader. There is no any specific pins for for bootloader. You can use normal uart pins or I2C pins for bootloader.
