Folks: On the advice of one of the many replies I got, I changed the command file, p&e_preload.cmd from this: // erase the flash modules FLASH ERASE to this: // erase the flash modules FLASH ERASE 1 2 3 4 5 6 Life is looking good for this engineer. I appreciate all of the fast, knowledgeable, and supportive responses. This user group womps on anything similar at Google. I am a convert, and look forward to further guidance here, as well as putting in my own $0.02 once I've grown a little wiser. Thanks again for everything! -Mike |

Hi Doron, Thanks for your feeback. Let me furnish you some details whcih could help to sort out this issue.The Nohau s/w i am using is providing both the check boxes for FLASH and EEPROM in the tools|PROM Programming window. And the version of the tool i am having is Seehaau for EMUL12-PC Version: 3.1217B.Built on 12/17/2001. I hope this will not be so old version as you hinted. And I have checked out the option to Program the EEPROM and selected the start addres as 0x3000. I have ensured that my .sx file has the right address and data and its look something like S0530000433A5C70726F6A656374735C45736974655C436F64655C303645534954455F 5235365F4B45585C73313264703235365C45534954455F4B45585C436F64655C656570 726F6D5C6E766D6465662E70726DC9 S10730005060D2E165 S1043FF8F8CC S9030000FC But when i selected the program option I am getting the following waring Attempt to load outside valid flash memory range. Attempt to load from address 0x3000 to address 0x3003, which are outside of the valid address range of 0x4000 to 0xFFFFFF. This attempt was ignored. Loading of data inside the flash memory range will be done. Cmd: Event_Message And upon selecting the continue option i am finally a waring like Warning EEPROM programming not yet working here. This warning was detected in file: "c:\nc12\hh12_32\HH_FLASH.C" at line 1512. Cmd: Cfg_FlashExecute Date: 7/31/2003 Time: 10:48:29 AM This made me believe that this version of my s/w is not supporting the eeprom download.We are using the licensed version and I have to see the option of using a trial version.I think with this you would be able to trace the problem.

Hi Doron, Extreme thanks for your support.I will update my s/w to the new version.
