AM2434: PRU-ICSS Ethernet with PRP

Part Number: AM2434
Other Parts Discussed in Thread: LP-AM243

Our customer wants to use PRU-ICSS Ethernet with PRP on AM243x.

A star topology will be used for each of the two independent networks to connect multiple PRP nodes consisting of multiple AM243x boards and one host machine.

I understand that if one network fails communication will continue as normal on the other network since packets are always sent to both networks.

After one network fails, is there a delay until recovery to continue communication on the other network?

If so, how long is the delay?

Our customer wants to test with multiple LP-AM243 for the topology described above.

Can they test with the HSR_PRP Demo in the MCU+ SDK?

Hi,

I have an additional question.

Can a normal L2 switch be used for each of networks to connect PRP nodes?

Best regards,

No there will not be any delay as the alternate/other network is already existing, so the communication continues on second one.

Daisuke Maeda said:

Yes they can test with this example. This demo has two board test showing how even when the connection breaks for on port, communication continues on other port.

Let me know if you need help with anything else.

Hi Nilabh A-san,

Thank you for your reply.

The latest release of LP-AM243 seems to be the E3 version with older silicon (SR1.0) device as part number "XAM2434ASFGGAALX".

The production release of AM243x will be SR2.0.

Is there any problem for our customer to evaluate using LP-AM243 with SR1.0?

Best regards,

Daisuke

Hi Daisuke-san,

There shouldn't be any problem evaluating with the SR1.0 LP-AM243x. However, AM243x SR2.0 should be used for any production-level designs.
