Hello all,

I need to erase flash Block 4 (address range 0x8000 to 0xBFFF). "S12(X) Debugger
Manual" (Revised: August 10, 2010) shows two methods to do that

1. Selection of the flash block in "Non Volatile Memory Control" dialog box and clicking "Erase" button. Doing that following appears in the "Command" window:

 

Vppon command file does not exist.
Vppoff command file does not exist.

in>

Checking flash:

in> FLASH
FP: FLASH parameters loaded for MC9S12DP512_V11(NVMIF2 rev 2,3,3,3,2) from D:\tuning\program\PEprogrammer\FPP\mcu03CD.fpp

MCU clock speed: 2008000 Hz
Block Module Name Address Range Status
0 EEPROM 400 - 7FF Blank - Unselected
1 FLASH_4000 4000 - 7FFF Programmed - Unselected
2 FLASH_C000 C000 - FFFF Programmed - Unselected
3 ALL_PPAGES 208000 -3FBFFF Programmed - Unselected
4 FLAT8000_P20 8000 - BFFF Programmed - Unselected

2. Typing command in "Command" window:

in> FLASH ERASE 4
Vppon command file does not exist.
Vppoff command file does not exist.

Checking flash:

MCU clock speed: 2008000 Hz

3 ALL_PPAGES 208000 -3FBFFF Programmed - Unselected
4 FLAT8000_P20 8000 - BFFF Programmed - Unselected

As you can see no error messages are displayed, but the desired block is NOT erased.

However, when I command erase of whole non volatile memory:

in>FLASH ERASE
Vppon command file does not exist.
Vppoff command file does not exist.

Checking:

in>FLASH

3 ALL_PPAGES 208000 -3FBFFF Blank - Unselected
4 FLAT8000_P20 8000 - BFFF Blank - Unselected
