Hi,

Is it possible to configure iMX6 PCIE CX_ATU_MIN_REGION_SIZE? The RM is vague if it is or not. At one point in mention values between 4kB->64kB but not howto configure it.

49.10.45 iATU Region Lower Base Address Register(PCIE_PL_iATURLBA)

The CX_ATU_MIN_REGION_SIZE configuration parameter (Value Range: 4 kB, 8 kB,16 kB, 32 kB, 64 kB defaults to 64 kB)

Regards

Andreas
