I have defined a variable in the dflash 0x800000. The variable have the correct address in the map file. And in the MOT file the address 0x800000 also have the correct data.  But when I access the device via the JTAG, the address 0x800000 is not have the data ,is 0xFFFF. How can I  program the dflash via the JTAG?

Hi,

Dflash is not programmed by Pemicro debugger by default in case of CW2.10, so it is necessary to do some changes. Attached you will find dlfah.zip. Copy cfg file and bat file to this location:

c:\Program Files\Freescale\CW for MPC55xx and MPC56xx 2.10\pemicro\

Then open your project, press alt+F7, select Build Extras and change the setting as per attached picture.

Then change the paths in cfg and bat file, so it fits your project. Then it should program also dflash.

Notice that I created it for MPC5604P, so changed also the programming algorithm (PCP file) in configuration file (*.cfg) accordingly.

Regards,

Lukas

c:\!WORK\Temp10\MPC5604P - Program Cflash from Dflash - CW210\bin\internal_FLASH.elf" LOADTOFLASH -RESETFILE "mpc5600_z0h_vle.mac"

How should this command line be changed? Is there a reference?

Thank you
