Table 5-2 Common hash values and the queried result
Number Name Description Response
5555 PROD_ID Standard product identifier 18
6857 CRC Result 16 bit CRC signature of the
STM-2XM flash memory, used
to verify that the proper code has
been installed at the factory. The
particular value for a
combination of a particular
version of bootloader and
application image is
documented in a database
registry used for manufacturing
support. This value is read only. CRC checksum of the CPU flash
memory, with 65536 added to it
65536 to 131071
11021 CODE_SUM The code checksum from
bootloader prefix block. This
sum details the specific version
of the application code that is
installed into the flash memory.
By comparing this value with a
list of known software releases,
the specific version can be
determined. This value is
algorithmically generated based
on the actual code pattern, so it
will change with any firmware
change, even if the embedded
version reply string was not
updated. This value is read only.
36581 PROD_BTYPE Product build type, copied into
dictionary from FRAM
configuration block. This value
defines the hardware platform
revision and/or configuration.
This value is read only. 0
Indicates that the FRAM
memory has lost the information
1 to 65535
53184 PROD_SRNO The internal product serial
number assigned to the
motherboard in manufacturing.
This value is read only. Returns an integer numeric
value
A value of 0 indicates a FRAM
memory failure.
