I am trying to set the FlexSPI frequency to 30 MHz for testing with DCD.


I added the following lines to DCD

but after downloading and a reset the values in the registers are not the ones I specified.


The XIP defines are set to


and qspi flash nor config has

.serialClkFreq = kFlexSpiSerialClk_30MHz, //kFlexSpiSerialClk_133MHz,

but the SPI flash is still running with 130MHz.


After a reset CCM_CSCMR1 is set to


and CCM_ANALOG_PFD_480 to


Why does DCD not set the values I specify?

In RT1020 reference manual below Table 8-41 is the following note

but I can't find a list of allowed block/target address in RT1020 reference manual. Where can I find them?


Kind regards,
