Kinetis MK20DX256VLK10 bootloader

francescoferrar — Fri, 18 Dec 2015 17:59:48 GMT

I need to update the FW for my board on the field.

Can you recommend a bootloader for MK20DX256VLK10 micro among the many possibilities that Freescale offers?

The time to implement the solution is few, this is why a quick fix would help me.

Best Regards

Francesco

Hi Francesco Ferraro,

Do you want to use the UART bootloader?

If yes, you can refer to the application note and it's sample code.

The application note is AN2295:

The according sample code is AN2295SW:

Wish it helps you!

If you still have question, please let me know!

Have a great day,
Jingjing

Hi Jingjing

I resolved. My board is connected to the host via usb cable.

I ported freedom_bootloader for K64F from FSL_Kinetis_Bootloader_1_2_0

thanks anyway for the reply

Francesco
