Title: How to Disable SoftICE mode
Post by: Mucter on April 21, 2010, 11:06:04 pm
I have tested My target to enter SoftICE mode.
My target entered to SoftICE mode successfully.
But I couldn't find out how to disable SoftICE mode using Flash magic.

The Datesheet says in Table 12,Record Type 07
----------------------------------------------------------
07 Reset serial number, erase user code, clear SoftICE mode
:xxxxxx07cc
Where:
xxxxxx = required field but value is a ‘don’t care’
07 = reset serial number function
cc = checksum
Example:
:00000007F9
----------------------------------------------------------

ISP -> Serial Number -> Reset Serial Number seems to this function.
But there in no Keyword "SoftICE" in this dialog box.

SoftICE mode isn't documented by NXP therefore there are no references to it in Flash Magic.

Thank you for replying.

I only advise that it is better for "Serial Number" dialogbox's Reset Serial Number sub box to
have a following red note.

WARNING: Resetting the serial number will erase not only serial number but also
user code and SoftICE mode.

-----------------------
See NXP's Datesheet in Table 12,Record Type 07.
"07 Reset serial number, erase user code, clear SoftICE mode"
seems Documented about how to disable SoftICE mode at least.

PS.
top window's web link bellow doesn't work!
