PCIe EP DMA write to i.MX6 RAM

[egabay1]

Hi,

Under the following conditions:

-. i.MX6 configured as PCIe RC

- The i.MX6 is connected to PCIe EP

- The EP wants to perform DMA write operation to the I.MX6 RAM

Does this scenario supported?

Thanks,

Eyal

Hello Eyal,

In EP's system, EP can access the reserved ddr memory    (default address:0x40000000) of PCIe RC's system, by the   interconnection between PCIe EP and PCIe RC. So I don´t see a problem.

Here is a link of a validation

i.MX6Q PCIe EP/RC Validation System 

Have a great day,
Jaime
