3.3.3.3 Board reset operation
The BCU reset command sets all rails to the default large current measurement range. This ensures that the selected
current-sensing resistor does not lower the voltage of a power rail below the operating range of the device and cause failure to
resume proper system operation.
The reset command is as follows:
• For Linux:
$ sudo ./bcu reset -board=imx8mpevkpwra1
• For Windows:
.\bcu.exe reset -board=imx8mpevkpwra1
• Hotkey in TUI: 5
