PYNQ-Z2 features a hardware watchdog, which can be seen by executing
wdctl. Unfortunately the
internal reset do not seem to be enabled on the kernel:
[3813653.241660] watchdog: watchdog0: watchdog did not stop! [3813658.511259] cdns-wdt f8005000.watchdog: Watchdog timed out. Internal reset not enabled
Xilinx Wiki - Cadence WDT page states that I can activate it in the device tree.
Where can I find the device tree for PYNQ-Z2?
