I have the following hardware configuration FS6500 and MPC5777C. My application configures the SBC to have INIT_FSSM and INIT_FAULT reaction to trigger FS0B and RSTB as well as the FCCU lines ERROR_0 and ERROR_1 (IO_23) on the SBC side.
My question is: What can I do to disable the SBC watchdog if I want to go to a Programming state (this will jump usually to a bootloader) to execute ERASE and FLASH process?
Also, is it possible to disable the WD operation at anytime?
Thanks!

Hi
If you want to disable the watch dog,please enter into debug mode of SBC.
Hello,
Thanks for your reply. Unfortunately DEBG mode requires a HW line to be pulled and a POR. In our application we are in RUN mode and at some point of time either for flashing purposes or after run (prepare the ECU to sleep) we want to disable the Q&A or the RESET of the FS6500.
Thanks!
Understand your question,but I am afraid that is difficult to control disable watchdog during the system active.
