K64 serial flash update

roymessinger — Thu, 12 Jan 2017 19:05:59 GMT

Has someone implemented the serial flash update on the K64?

I've found this link regarding the flash update, but nothing there is concerned with K64 or any K family component.

Any hints?

The developer's serial loader is available for the K64 at

As well as KBOOT UART, SREC/iHEX UART, SD card, Ethernet, USB-MSD, USB-HID (including KBOOT), USB-CDC and memory stick loading as described in

Hi Roy messinger,

About the serial flash update on the K64, you can use our official KBOOT which can be download from this link:

http://www.nxp.com/applications/solutions-for-the-iot-and-adas/smart-connected-solutions-for-the-iot/smart-cities-in-the-age-of-iot/smart-energy/off-grid-solar-power-inverters/kinetis-bootloader:KBOOT?&&fsrch=1&sr=1&pageNum=1

This Kboot contains the K64 uart flash bootloader.

Wish it helps you!

Have a great day,
Kerry

Thanks, kerry and Mark.

Kerry,

Regarding the Kboot, does it enable programming the k64 via UART?

This is my intention, sorry for not pointing that out...

My next step will be implementing a boot loader which will enable loading a first image, then go to the second image.

Is this a good start for my needs or am I mixing things up?

Thanks.
