Firmware Recovery
Problem
The replacement of a module or an unsuccessful installation of firmware may result in
the PRM indicating a CF for internal communications problem.

OK: FW versions are compatible and can be upgraded without further actions.
Not OK: FW versions are not compatible and can NOT be upgraded. First, the PRM
master FW must be changed to the same FW version as the slaves. Then the FW
upgrade to the desired version is possible.
Important - It is strongly advised to disarm the slot before executing the
diagnostic command
“
sver
”
.
To obtain the FW versions, do the following:
1. Start IMx-M Manager serial interface to PRM.
2. Put the slot in disarm mode.
3. Use
Advanced debug mode
, run command "
Slave version
" from the menu. This
command automatically perform the diagnostic commands
intd0
and
sver
.
4. Evaluate the results of
intd0
.
If the result from
intd0
shows firmware versions on all lines, then there is no
internal communication problem. FW upgrade can be done without further
actions.
If the result from
intd0
shows firmware version 0000 on some of the lines,
then go to the step 5.
5. Evaluate the results of
sver
.
If the result shows firmware version that was 0000 in step 4 but now is non-
zero, then there is an internal communication problem. Check the table "FW
version comparability" and continue to
Resolution
.
Resolution
To solve the problem the PRM master firmware (IOM) must be downgraded to the same
firmware as the slaves.
1. Use the recovery firmware installed in the IMx-M Manager directory.
