Boot Loader for MCF52223

[JimMcP]

I need to write a serial (UART) boot loader for the MCF52223 Coldfire. To be able to flash the device remotely. Is there documentation and /or code examples on this.

Thanks

Hi Jim

Most of the Freescale evaluation boards (EVBs) come with a resident monitor program called dBUG. Amongst other things, this lets you download code and flash it. Source code of dBUG is available from Freescale's web site.

Unfortunately, the 52223 EVB doesn't come with dBUG. However, the MCF52233 is pretty similar to the MCF5213, a processor for which dBUG source *is* available.

You can download the source of the M5213EVB version of debug from the following link:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=M5213EVB


I think this would give you a useful starting point, including how to use the serial and Flash. It's actually pretty easy to adapt this code to work on the MCF52233, so you could start by getting dBUG working.

Hope this helps
