Hello,

 

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

XIP_BOOT_HEADER_DCD_ENABLE=1
XIP_EXTERNAL_FLASH=1
XIP_BOOT_HEADER_ENABLE=1

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 8.7.2.1 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,

Stefan
