You can capture the overall PMC status and error status using the jtag_status and error_status commands from XSCT. 

xsct% device status jtag_status
  • Check BOOT_MODE [15:12] bits
  • Check DONE [34] bit – This indicates configurations completed
  • Ensure the voltages supplies are detected successfully – Bits [8:11] should be asserted
xsct% device status error_status
  • Expected error_status value is 0x0 after board is power cycled and Power-on reset (POR) is asserted
