Hi All, I am looking for a flash programmer for Motorola MC9S12DP256B with the following functions: It can load a firmware image (say S-Record) into MCU and overwrite the existing (crashed) firmware inside the MCU. We also have to keep some calibration data that were saved in EEPROM and Flash ROM on MCU, i.e., we can select which area to overwrite and which area to keep (protect). Can anybody confirm that SCBDMPGMR12 is such a device that fits my need? I contacted vendors, but they don't have technical person that can answer my question. Thanks in advance. |

Chengrong, The SCBDMPGMR12 is designed for high speed programming in a production environment (the MC9S12DP256B can be programmed in under 10 seconds) and does not have the capability to selectively erase and program portions of the target Flash or EEPROM.

Thank you Gordon for your quick response. I may have described my problem not so clearly, the actual memory map for our firmware is: 1. EEPROM (0x0400 - 0x0FFF): Calibration data (different for each unit). 2. Page 30 - 33: Look-Up-Table: (different for each unit). 3. Page 34 - 3D, 3E, 3F: Code Item 1 and 2 should be kept (protected from overwrite), item 3 is overwritable. I didn't mean to select inside EEPROM or Flash ROM Page, where to overwrite and where to protect. I am reading the "Reference Guide for Serial BDM Programmer" written by you, is it possible for me to use LF *** to load S-Record to my desired Flash Address, and leave the protected area untouched? Thanks.

Chengrong, >..is it possible for me to use LF *** to load S-Record to my >desired Flash Address, and leave the protected area untouched? The LF command is capable of loading multiple S-Record files into the BDM Programmer's Data Flash, however, before you can load new data into the BDM Programmer's Data Flash, it must be erased. This means that you would have to reload all of the Flash and EEPROM data (including the code for pages 34 - 3D and 3E & 3F) for each unit programmed. While it's possible to use the BDM Programmer in this manner, it's probably not the most efficient way to program a target device since all of the code & data must first be loaded into the programmer before the target can be programmed. The BDM Programmer was really designed to program multiple target devices with the same Flash & EEPROM data as quickly as possible. For your application, you would probably be better off using the P&E Multilink cable along with their programming software.
