Hello Experts,

I try to disable eeprom erase during downloading, so i configure in CW debugger window(File->Configuration->Load->click 'Advanced'->select 'EEPROM'). But the result is eeprom stil will be erased to 0 or 0xFF after downloading before the program is RUN.

IDE: CW_HC12_v5.1_EVAL(download from freescale web)
Debugger firmware:P&E USB Multilink
prm setting:
SEGMENTS  /* Here all RAM/ROM areas of the device are listed. Used in PLACEMENT below. */

/* Register space  */
/*    IO_SEG        = PAGED         0x0000 TO   0x03FF; intentionally not defined */

/* RAM */
      RAM           = READ_WRITE    0x2000 TO   0x3FFF;
/* D-Flash */
      DFLASH        = READ_ONLY   0x000400 TO 0x0013FF;

PLACEMENT /* here all predefined and user segments are placed into the SEGMENTS defined above. */



Can you give the suggestion about this issue? Thanks
