I have a question about what should happen after a watchdog reset. I'm
using CCS 3.1 and a F2812 eZdsp board.
After I flash the chip, The PC is at 3DC000, from this point, I hit run and my
code begins executing. I purposely have a watchdog reset in there. When this
watchdog times out the reset occurs but never gets back to my code. Once I hit
halt, the PC is at 3FFC00. It stays there forever.
In CCStudio, if I hit Debug...Reset CPU, it will go to this same address
(3FFC00). But if I hit Debug...Restart, it then goes to 3DC000, and is able to
execute my code again.
My question is, how do I get the watchdog timeout to go back to the 3DC000 and
restart my code automatically?
Some of my linker file is pasted below for reference.
Not sure if the .reset or vectors being DSECT have anything to do with it.
Thanks in advance for any advice!
