i.MX8M Mini PCIe iATU address overwrite DDR address

[m_c]

In i.MX8M Mini PCIe iATU address is start at 0x8000_0000h (Ex: iATU Region Control 1 Register. (IATU_REGION_CTRL_1_OFF_OUTBOUND_0 is 0x8000_0000h). But DDR address is 0x4000_0000h~0xffff_ffffh. Will it conflict if DDR RAM size is 2G bytes?

Hi,

PCIE IATU address is address translation, and does not really occupy the DDR address space.

Have a nice day!
