Problem with loading code to Flash w/P&E MULTILINK

kji — Fri, 09 Jun 2006 00:47:19 GMT

I use CW12V3.1 w/P&E MULTILINK on 9S12E64 (4MHZ oscillator). Code is not able to be loaded to the Flash. (Memory model is selected as banked). Please anyone help this out..

Memory Map information on command window:

When I got some new 9S12DG128 chips in, I found that I had errors that didn't make sense sometimes, and I had to manually tell CW to erase everything. Evidently the security bit or something got set.

And just for a reference, I just took a look at my project.ini file, and in the ICD12 section I show the bank at 3F (for C000) is Unbanked. Now I didn't set that up, it was done automatically for me. In the real time debugger, in the ICD-12 pulldown, I show that C000 is listed as 'physical' from C000 to FFFF for the debugging maps.

Thank you for your information. "NON_BANKED 24 R 0xC06D 0xC084 ROM_C000" is file P&E_ICD.map. So i guess I don't have to reset up on my case.

I also changed 8000-BFFF to C000-FFFF on the ICD-12 pulldown. unfortunately problem is still unsolved.

I guess I have to manually tell CW to erase everything but how to do it?

Thanks again.

Usually you should not have to change the factory setting in the icd12.

What I dont understand in this prm file snippet:

> ROM_C000 = READ_ONLY 0x0000C000 TO 0x0000FF7F;
> ROM_PAGE3F = READ_WRITE 0x003F8000 TO 0x003FBFFF;

Well, this is the same flash memory used twice as far as I know. Once as READ_ONLY and once even as READ_WRITE.
Why do you specify the ROM_PAGE3F page at all?

Same thing for those two:
ROM_4000 = READ_ONLY 0x00004000 TO 0x00007FFF;
ROM_PAGE3E = READ_WRITE 0x003E8000 TO 0x003EBFFF;

Can you flash a normal, unmodified application generated by the project wizard?

I have two different MCUs - 9S12E128 and 9S12E64.

I have created two simple projects by PE on CW3.1 for both MCUs (same function) . BTW, I seleted memory model as Banked.

The 9S12E128(on an evaluate board) works great but 9S12E64 (a PCB) has same problem.

Here is PE auto-created flash information in .PRM file.

SECTIONS
      /* List of all sections specified on the "Build options" tab */
      RAM = READ_WRITE                0x00002000 TO 0x00003FFF;
      ROM_C000 = READ_ONLY            0x0000C000 TO 0x0000FF7F;
      ROM_PAGE3C = READ_ONLY          0x003C8000 TO 0x003CBFFF;
      ROM_PAGE3D = READ_ONLY          0x003D8000 TO 0x003DBFFF;
      ROM_PAGE3E = READ_WRITE         0x003E8000 TO 0x003EBFFF;
      ROM_PAGE3F = READ_WRITE         0x003F8000 TO 0x003FBFFF;

I also tried to disable ROM_PAGE3E-F.still same issue

Thanks.

I found out a design issue on the custom board. Code is still not written to flash completely but improved after the hardware was fixed. The issue now is that flash 00004000-00007FFF only is disabled (see below). Since the same BDM pad and code have been used on an evaluation board never had problems. Does the board still have other issues? Please advice.
