Chapter 12 E8 Update
When connecting to an E8 interface adaptor board, FDT will check that the E8 firmware (adaptor software) is
the correct version and correct type for supporting the connection to the selected device. If there is a mismatch
then FDT will offer to update the E8 firmware in order that the connection can be continued. Also if the E8
Adaptor checksum is incorrect, an update will be required. Note that in some cases, an update to an earlier
version number may be required if the current version does not support the selected device. It is very important
that the E8 is not unplugged during the update process because this could result in the E8 being left in an erased
state.
NOTE - The E8 has two firmware areas, a ‘Level 0’ and a ‘Level 1’ (the Bootstub and Adaptor Software
respectively). Typically FDT will only update the Level 1 area but in some cases a Level 0 update is also
required. This is usually seen when connecting with E8Direct (see Chapter 13 - E8Direct) for the first time and
will result in a slightly different update process, shown below for comparison:
Level 0 and Level 1 update:
E8 target power has been set to ON at 5.0V
Connecting to device 'R5F21174' on 'E8'
Configuration:
'BOOT Mode' connection - using emulated interface
Opening port 'E8' ...
Checking for E8 update...
Adaptor checksum OK
Processing Data file :'c:\FDT\ADPFiles\E8-Rel-Img.mot'
Mismatched Bootstub (Level 0) version number found (current E8 version =
1.00.01.000, FDT holds version 2.00.00.000, FDT requires version 2.00.XX.XXX)
Update selected
Adaptor update started (do not unplug)...
