NVIDIA Orin Voltage Monitoring via VRS12 (VMON)
- Initial configuration and set up for VMON, executing the HW
BIST provided by VMON
- Programming the VMON Chip with thresholds for UV/OV
detection
- Continuous monitoring of VMON Reset pin indicating UV/OV and
reporting the detected errors to Error handler module
- Implements safety measures like toggle check for VMON NIRQ pin,
ACT/SHDN and ACT/SLP signals.
- The following error scenarios are detected
- VMON Chip internal errors are detected via BIST failure
- I2C communication failure while read/write operations are detected via CRC
- Errors during the programming of VMON chip are detected by reading back the values
written to the VMON registers.
- In the current SW functionality, VMON error are notified to
Error handler module, and the board is powered off.
