HS Device Does Not Reboot Successfully on Warm Reset Getting Triggered by Watchdog Expiry
AWR6843 ES2.0
A warm reset triggered by a watchdog expiry (MSS Wdog) , a software register write (SOFTSYSRST), or an external warm reset pin does not ensure a successful reboot of the device in a secure device (HS device).
A warm reset should not be triggered externally or internally by a watchdog expiry, a software write, or other trigger mechanisms.
To initiate a reset cycle, external circuitry should be used on the sensor design. The external circuitry uses the watchdog, nERROR OUT monitoring, or other kinds of GPIO signaling to trigger a reset using the nRST pin of the device.
