Hello,
According to AN12077:
“The Arm Cortex-M7 specifications require the size of ITCM/DTCM to be
a power-of-two number, which can conflict with the FlexRAM
configuration capability. Avoid access to the empty RAM space
configured by the corresponding FlexRAM configuration.”
Customers can use IOMUXC_GPR_GPR17, as described in section 2.1.2
(Definition of the memory type size) of the app note.
Have a great day,
Yuri
