26.4.5.2 Corrupted secondary bootstrap
If the secondary bootstrap of your SMP Gateway is corrupted, use one of the following
procedures.
SMP 4 or SMP 16
Contact Cybectec Technical Support.
SMP 4-20 or SMP 8-40
Normally, SMP Loader communicates with the secondary bootstrap program of the
SMP Gateway. However, if the secondary bootstrap is corrupted, SMP Loader has to
communicate with the primary bootstrap in order to load a new secondary bootstrap.
In that case, you have to put the primary bootstrap in Update mode. In this mode, you do not
have access to the usual SMP Loader functions. All you can do is load the bootstrap
programs. Also note that SMP Loader will automatically set its communications speed to 19,200
bps.
Proceed as follows:
Simultaneously hold down the reset, TEST1 and TEST2 buttons until all four LEDs
(power, watchdog timer, ST1 and ST2) turn amber.
Release ONLY the reset button and keep holding down the TEST1 and TEST2 buttons until
the first 2 LEDs (power and watchdog timer) go from amber to red, and the other 2 (ST1 and
ST2) go from amber to green.
Note: At this point, the information displayed on the LCD is not valid and is, therefore,
to be ignored.
Transfer the secondary bootstrap program to the SMP using SMP Loader (see “Transferring
Files to the SMP Gateway”, 237).
