Agustin,
The Flash Programmer is currently only handling some ranges, as they are
listed.
Indeed, if you want to erase one sector, you will not be able to do it
"transparently".
CodeWarrior for HC(S)12 does not provide a sector granularity for flash
erasing. Also the Flash Programmer will overwrite all protections to get a
full
access and will eventually erase the entire part.
However, please find here below a script example that you can adapt to
erase the sectors you want.
The "erasesectors.cmd" script example here below erases sector in
ppage
$3E, except the last one. Create the file, adapt it to what you want to
erase, and store it in the same folder as your project.
You can call the script from a Startup file, or from the Command window,
for example, with the CF command.
CF erasesectors.cmd
(if you enter CF without parameter, you can browse for the file).
//***** BEGIN: erasesectors.cmd file ***************

Thank you! This is what I need!
When you say "a finer granularity" you mean that if I want to erase
only
part of a page, I will have to use debugger commands as "wb"
"ww" to
configure flash to write sector by sector?
I guess my bootloader will take only 2K of protected flash area (at the
end of its development) and I will have to erase all flash but the
protected area when the debugger starts. Is this what you say that will
need more granularity?
regards.

Agustin,
First:
-----
The new command "FLASH AEFSKIPERASING" has been created to specify non
volatile memory blocks to protect from mass erasing at application loading.
The command should be placed in a "Preload" command file of your
project
(reported in the ICD12 release note).
The command syntax is:
FLASH AEFSKIPERASING <blockNo>
with blockNo = {number["-"number][","]}
For example, "FLASH AEFSKIPERASING 0,2-4" avoids erasing flash blocks
0,2,3,4.
Reminder: Flash (and non volatile memory) modules and numbers can be
displayed when typing the "FLASH" command in the Command window. Also
the
Flash/Non Volatile Memory dialog list displays all modules starting from
block number 0.
When used, the "FLASH AEFSKIPERASING" command should be placed in the
"Preload" command file.
Then:
-----
I have posted a new flash driver library (only valid for ICD12 v6.1.11 and
later revisions) that features a clear separation between range $4000-7FFF
and $C000-FFFF.
http://f6.grp.yahoofs.com/v1/ACMgRFD_6IwA6isqdF2ATh0PMhKX_gPPCIkVb8x3an3jAdT
QMlpda78tvhQ8NijeLo31Ig8XxMAErT18AGJSDJ26iGo/fpp%27s%20for%20%20CW12V31%20an
d%20ICD12%20v6.1.11%20and%20later%20releases.zip
The driver lists, for DP256:
0 EEPROM
1 FLASH_4000
2 FLASH_C000
3 ALL_PPAGES
4 FLAT8000_P30
"FLASH AEFSKIPERASING 3" will avoid erasing all PPAGES, but sectors
in
$4000 and in $C000 will be erased, and eeprom (there is no erasing
implemented in FLAT8000_P30).
Installation:
-debugger closed.
-in CodeWarrior installation, "prog" folder, rename the
"fpp" folder.
-create a new "fpp" folder and unzip all posted files in this folder.
Finally:
If you want to keep the bootloader, I guess you will prevent the FLASH_C000
from being erased.
If you want a finer granularity, you will have to use debugger commands to
erase by sector. You then can forget all this here above. The debugger does
not provide this granularity currently. But I can post you a command script
to do this, if you want.
I hope this help.

Gilles

Hi Augustin.
The "P&E_ICD_Erase_unsecure_hcs12.cmd" is NOT the file that is
executed
when you start debugging your application. This file is only called when
you select the "Unsecure..." menu entry, in order to Unsecure the chip
when
"BDM-secured".
Before giving you more hints, please type the "VER" command in a
Command
window.
I need to know which version of the ICD12 (or P&E Multilink/Cyclone Pro)
DLL you have.
you should get, for example:
ICD12 6.1.9 Build xxxx
or
P&E Multilink/Cyclone Pro 6.1.14 Build xxxx

Gilles

Hi all,
I want the codewarrior (CW) debugger to erase only a part of the flash
when it starts.
I can see in the "P&E_ICD_Erase_unsecure_hcs12.cmd" file that the
debugger will make a MASS ERASE before programming the flash.
I want to keep my bootloader programmed into the flash although any of
my colleges use the debugger on our targets. I can't find documentation
regarding debugger commands.
Does anyone can help me on this topic?
Any other idea to keep the bootloader programmed?
thanks in advance.
Agustin
