Downloading Code Files
When to
Download
There are two reasons for downloading code files:
• If the iBox has performed self-diagnostics and determined that the flash memory
is either erased or corrupt, it will display the D25S> prompt on the system
monitor when it requires code files to be downloaded
• If the iBox software program features need to be changed or upgraded, the
existing flash memory can be erased, and new code downloaded.
Programming
Flash Memory
There are three ways to program iBox flash memory (the one you use will depend on
your system options and network type):
• Connect a PC, running terminal emulation software, to the WESMAINT port.
This procedure is described below.
• Use SGConfig to access the iBox through the WESMAINT port.
• Using a parallel port adapter and software utility, connect directly to the iBox
BDM (Background Debug Mode) port. This procedure, which facilitates very
fast downloads, is used during the manufacture of the iBox.
Before
Downloading
When a new code image is downloaded into the iBox flash memory, 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, the following message (or a similar message) displays:
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, refer to the SGConfig online help on how to set the iBox
Device Properties to increase the Base System area.
Note
Using the Windows HyperTerminal for a code download procedure can take up to
two hours to complete.
