When you implement the built-in security feature on the DP256B mask 1K79x running Normal Single Chip mode, you cannot erase and write EEPROM and flash on the device. (From Freescale ERRATA MUCts00603 and MUCts00604.) We need to be able to reprogram the MCU while in the field. In order to do this, our firmware update PC tool launches the Bootloader on the MCU, unsecures the device using t...
Flash programming from a bootloader

Hi folks Has anyone here ever successfully programmed flash in a 9s12 device from a bootloader when the chip is secured? The chip I am using is the 9S12DG128 3l40K mask set which has the common EEPROM/FLASH programming error fixed. I am still having some troubles and

Hi Guys I feel like I've come full circle. Last year I asked if any one had successfully managed to get a eeprom burner for HCS12 to work in linux. I'm back at again this year, if you've managed to get it working, could you let me know what programs you use and what bdm? I'm currently doing all the development work on linux, then copying it all across to windows and running NoIce de...

Hello, I use 9S12E64 and internal flash for Booter and external flash for application. Because there's no data EEPROM, Application uses internal flash area (1sector) for NVM data. Currently I use softec InDART BlazeProgrammer, and it seems it only support mass era

hcs12mem 1.4.1 is available. http://cml.mfk.net.pl/hcs12mem/ Previously known as hc12mem, now renamed to hcs12mem, due to some confusion which MCU family it supports: hc12mem name suggested that's HC12 family, but in reality it currently works only with S12 chips. hcs12mem is a tool for S12 MCUs, allowing for reading/writing internal memories (FLASH/EEPROM), protecting/unprotecting ...

http://cml.mfk.net.pl/hc12mem/ I made some improvements to my hc12mem program for HCS12 MCUs. hc12mem is a command line tool for erasing, reading and writing FLASH and EEPROM internal memories, it can also protect/unprotect whole MCU. Works under unix derivatives (FreeBSD and GNU/linux tested), and MS Windows

hc12mem v1.2 ------------ - added support for Freescale's serial monitor (Application Note AN2548) Using this serial monitor in target FLASH memory, hc12mem can: - erase,read,write,protect target EEPROM - erase,read,write target FLASH - securing/unsecuring is not supported, due to monitor presence So for now, hc12mem can access HCS12 MCU memory
