DP512 Self flash programming

I would like to upgrade the flash program of DP512 MCU by CAN bus. Would DP512 has Bootloader to support this function? Can DP512 overwrite its own flash memory?

 

Thank you.

Hi Henry,

Please look at our application note AN2546 HCS12 Load RAM and Execute Bootloader User Guide

http://www.nxp.com/files/microcontrollers/doc/app_note/AN2546.pdf

https://www.nxp.com/webapp/Download?colCode=AN2546SW

Related application note with AN2546 update to S12XE is AN3391 LFAE Bootloader Example and Interface for use with AN2546 (CAN bootloader for S12XE)

http://www.nxp.com/files/microcontrollers/doc/app_note/AN3391.pdf

Other bootloader code which could be used with S12D is AN3275 S12 All-Access Bootloader for the HCS12 Microcontroller Family

http://www.nxp.com/files/microcontrollers/doc/app_note/AN3275.pdf

This bootloader uses just SCI channel to loading code into MCU, CAN interface missing there.


I hope it helps you.

Have a great day,
RadekS
