Interesting. No TWD timer on this one?
Good question, adding Felipe to cc. It eems to be there in
the TRM in "Table 2-3. L4_PER Peripheral Memory Map" as
MPU_PRV_TIMERS. Also seems to actually work with the
attached patch:
TWD is useless on this machine since single core and TWD
as know die in low power states. All the broadcast stuff
is for SMP machines.
Above is expected and correct and no patching is needed.
