Baremetal sample for Tower board

renjithvamanan — Fri, 14 Feb 2014 08:11:40 GMT

Hi,

I am really sorry if this is a RYFM kind of question :smileyhappy:

My requirement is to start writing a bootloader fot MK60FN1M0 processor.

I have a tower board. To start with I need a sample app which is not running on MQX RTOS, to make the boot loader light.

Is there any bare metal hello world sample available that running on tower board.

I am looking for a sample to understand the processor initialization part etc that I may also have to incoporate in my boot loader.

Thanks,

Renjith

Hello Renjith:

You can find example codes in the package called "KINETIS_120MHZ_SC". This is available from the next link, under Snippets, Boot Code, Headers, Monitors, etc.

K60_120: Kinetis K60 Ethernet Crypto 120/150 MHz MCUs

And whenever you are in doubt and do not find answers in the community, please feel free to post you own question.

Regards!

If somebody gets error saying "Undefined macro or opcode: export fpu_asm.s" while building the bare metal aplications,

Please refer to this problems building bare metal examples for kinetis K70
