Introduction

Enhancements

  • Added support for viewing system usage information directly in the console interface.

Fixed Issues

  • Resolved an issue where the system would enter a continuous reboot loop when the RJ45 hardware sub-board encountered problems, which previously rendered the entire system unusable.
