HCS12 flash programmer

Started by Nam SungHyun March 11, 2004
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 erase. So, If I want to update Booter,
Application's NVM datas are also erased.

Is there any programmer I can use for this environment?
I want to erase only Booter area when I upgrade Booter.

regards,
namsh




You might look at Prog12Z programming from P&E microsystems. You can do what you are asking and you can also set up an init file or run it from the command line to automate some of the commands required to only erase parts of the memory.

Good Luck

Steve
