Yes, this was idea to use MdeModulePkg/Universal/WatchdogTimerDxe/WatchdogTimer.inf and if needed, install a custom protocol for hardware wdt. And this to be used by platform specific code. > Regards, > > Leif _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
