PCIe EP DMA write to i.MX6 RAM

egabay1 — Mon, 03 Apr 2017 14:22:36 GMT

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

Have a great day,
Jaime
