In i.MX6 Quad, could you tell me the conditions that make the following areas accessible?
0x0100_0000~0x01FF_BFFF 16,368KB PCIe
Currently, read access to this area causes an abnormal state (freeze).
I understand that this area is used for outbound transfer and MSI interrupt.
The register area below can be read and written normally.
0x01FF_C000~0x01FF_FFFF 16KB PCIe registers
The current setting is described below.
- PageTable of the corresponding area is defined collectively with other peripherals as a device.
// 0x01000000 - 0x02bfffff : I/O Access #2
- The PCIe peripheral clock is set as follows.
* These are set after confirming that LOCK == 1 after setting POWERDOWN = 0.
Please let me know if there are other necessary information.
