Confirm that power rails are detected successfully. To ensure that the power rails voltage value is correctly configured on board, read the SysMon registers. 0xF1110100 (PWR_STATUS) and 0xF111010C (PWR_SUPPLY_STATUS) are the registers that supply the power rail.

To read the registers, run the following:

xsct%mrd -force 0xF1110100
xsct%mrd -force 0xF111010C

Confirm that power rails are detected successfully. To ensure that the power rails voltage value is correctly configured on board, read the SysMon register 0xF111010C (PWR_SUPPLY_STATUS) by running the following:

xsct%mrd -force 0xF111010C
Table 1. 11.1.21 Register (PMC_GLOBAL) PWR_STATUS
Register Name Address Width Type Reset Value Description
PWR_STATUS 0xF1110100 32 RO 0x00000000 This register provides the Domain Isolation Status.

1 = isolated

0 = non-isolated

The register is only reset by the Power-on Reset and maintains its state through a System Reset or Internal Power-on Reset.
