bootloader for K70

[johnatkins]

We would like to reprogram a Kinetis K70 from UART4 on the K70. This is a way to implement a firmware upgrade. Does anyone have anything like this, or any advice?

Thank You.

John

Hello john,

I just finish to debug a bootloader for a KV46,

In the original version, the Bootloader is very powerfull, it's scanning all the possible link (as a slave)

I2C,SPI, CAN and UART

You can use any uart you want you only have to modify the original version 2.0.0 to adapt it to you hardware.

check the files :

Hardware_init_Kxx.C files.

Peripherals_Kxx.C files

Peripheral_pinmux.h

No modification needed for kinetisflashtools
