Need help answering these question:
1- in what state does the FS26 end up into if I don't close the INIT_FS phase with 1 good watchdog refresh within the preconfigured 256ms timeout ?
2- Is the INIT_FS phase timeout configurable ? what's exactly happening with "WD_INIT_TIMEOUT_OTP" is it deprecated or not usable or planned for future use ?
3- Does the WD_DIS OTP bit Enables/Disables watchdog completely or just the timeout for the INIT_FS phase ?
4- From functional Safety POV, normally in Autosar projects when doing a transition between Application and Bootloader you issue an MCU reset, which asserts the release line and the FS26 will react by going back to INIT_FS phase, this mean the WDG can be ineffective for 256ms ... is that the intentional design ? any hints for how this should work "handling the FS26 WDG when transitioning from application to bootloader" ?

Hello Mohammed,
I hope all is great with you.
Please review the information below:
So it can be used to re-configure FS26 WDG and disable FCCU when transitioning from application to bootloader.

Thanks alot for the reply
1- Ok
2- No, I was just exploring the possibility to disable that timer to make it more strict
3- Ok
4- My assumption was that the Wdg should be expecting good refreshes even when doing a transition between APPL and Boot, but i think the current setup makes it a bit more relaxed way of handling the Wdg
