MPC5554 FLASH Program

[Shenovy]

Hi, I want to program different projecr into FLASH, how to control the erased FLASH address during Debug

According to your description I am not sure what you want to achieve.

There is an official binary driver with the documentation:

If your question is how to download code into internal flash, then use external debug JTAG/Nexus probe (Pemicro or other).

Im sorry for not describing my problem clearly. Here are detailed information:

I want to download two different projects(like APP 1 and APP 2) into the internal FLASH.

But when I use the CPROGPPCZ Programmer, it always erase the whole FLASH! 

So, I want to know how to download APP 2  into  the FLASH without erasing APP 1.

I see. It is needed to use programmer that is capable to erase each block individually as in the screenshot below:

Thanks first, I've tried this way before.

However, if I only erase one block, I can't programm the object file. It reminds me that I have to execute  the EM(erase module) command as in the figure below.

I would recommend to contact PeMicro support.

They should know how to overcome the issue (apparently you will have to use paid version of this software.

Or you could use advanced debugger as Lauterbach TRACE32 or other, offering scripting capability.
