Other Parts Discussed in Thread: AM3359

Hi, experts.

I have a plan to connect two of am3359.

I need a high speed communication between two of them.

1. Can you please check how to config two am3359? ( is it possible to set on is Master the other set to slave? I want to use each am3359 has a linux and ddr)

2. And how to communite between am3359 with high speed?

3. Is there EVM that connect two sitara?

Thank you.

Jay,

It will be wise to be familiar with features of AM3359. Also, to know what these features are for.

I assume you plan to connect both am3359 in the same pcb. You can either use I2C or MCSPI(Multi-Channel SPI). If you require high speed communication, SPI is the way to go. Here below is a good comparison of I2C and SPI interface.

Hi kel,

Thank you for the answer.

Yes I will use am3359 in the same pcb.

I've check and the problem is in case of using SPI the maximum speed rate is about 40Mhz but I need more speed rate.

It has a PCIe peripheral. Can I use PCIe to communite between MPU?

Thank you.

None of the AM335x family of devices have PCIe.

Hi, Paul.

Sorry, I've mistaken.

If i'm using am389x family?

They have a PCIe.

Best regards.

Hi Jay,

Yes, if you are going to use the AM389X. Further research on "how to do that", will eliminate your doubts.
