I try to develop the bootloader via usart and enternet for Kinetis K64 MCU. Is there any source code example?
Supports K64 for UART, USB, Ethernet, SD-card bootloading. Web server based loading occupies about 18k of space built with GCC.
You could try porting Emcraft's U-Boot here, but be aware it's a very old U-Boot and its Kinetis support is pretty thin and anemic.
I think the biggest bite would be the MCG differences between the K70 and the K64.
Maybe you could be a hero and fix all that...
