Confirm that the configured peripherals are out of reset.

  • Before initiating requests to any peripheral in the PS or PMC, make sure the peripheral is out of reset.
  • Check all reset registers in CRx (CRL, CRF and CRP) modules.

To read the QSPI reset register using XSCT, run the following command:

xsct%mrd -force 0xF1260300
