I would like to be able to force a processor
reset via software. Our software uses DSP/BIOS on a TMS320C6711 with
code composer 1.20. We have the reset line of the processor tied
to a watchdog supervisor circuit so one mechanism that works is to halt
Kicking the Watchdog. The method is inelegant and requires about a second
for the watchdog to do its thing (since the watchdog is setup to expect kicks
about 1/2 to 1 second apart.).
Now TI Document SPRA640A (Programming and
Debugging Tips for DSP/BIOS) indicates that a Jump to Address 0x00000000 should
result in a clean reset of the processor since this is the location of the reset
vector. Unfortunately, When I try this, I hang the software and the system
does not come back up.
Q1: Has anyone else tried to use this
method to implement a software reset, and any ideas why I am not seeing a clean
restart of the system?
Q2: Is there another way I should use to
force the processor to reset from within the firmware?
NOTE: We are NOT interfacing to the HPI
so I assume using the Warm reset features via the HPI is not an
option.
