Code Files:
When to
Download
There are two reasons for downloading firmware code files:
•
If the D25 has performed self-diagnostics and determined that the FLASH
memory is either erased or corrupt, then it will display the
D25S>
prompt on the
system monitor when it requires code files to be downloaded.
•
If the D25 software program features need to be changed or upgraded, the
existing FLASH memory can be erased, and new code downloaded.
Choice of Three
Processes
Three techniques for programming the FLASH memory are available. The
technique to use depends on system options and network type.
The choices are:
1.
A serial connection from a PC to the WESMAINT port, using third-party
communications software.
−
This procedure is described below.
2.
Use SGConfig, either via a serial connection to the WESMAINT port, or
via Ethernet using a TELNET and TFTP procedure.
−
These options are described in the SGConfig On Line Help.
3.
A third-party USB port adapter and software utility is available to connect
directly to the BDM port on the D25 WESDAC Board, which permits
very quick downloads.
−
This is the procedure used during manufacture of the D25.
Insufficient
Memory
When a new code image is downloaded into the FLASH memory of a D25,
the amount of memory reserved for the configuration’s data region, also
referred to as the “Base” region, may not be large enough.
If this occurs, then the D25 locks-up and a message similar to this will be
displayed:
The configuration’s data region overlaps the current
Configuration Header (NVHEADER). Relocate the
Configuration Header / NVRAM to <address>, or set data
size to <size> and re-download. Application will NOT
be started.
If this message appears:
•
Unlock the D25
•
Increase the base region memory. Consult the SGConfig Online Help for how to
set the D25’s
Device Properties
to increase the Base Region size.
