Hi,

Please provide complete details of your use case. Which SDK you are using - Linux or RTOS, what version, etc....

Hi Biser,

I am working on PROCESSOR-SDK-LINUX-AM335X 06_01_00_08 for PRP on TMDSICE3359.

There is some typing mistake in SDK documentation of Getting Started Guide

section 4.2.3.3.3. PRU-ICSS Subsystem Driver

SoC	ID	if number	ICSS TRM reference
AM3	0	eth0/1	PRU-ICSS
AM4	0	eth1/2	PRU-ICSS0
AM571	1	eth2/3	PRU-ICSS1
AM571	2	eth4/5	PRU-ICSS2
AM572/4	2	eth2/3	PRU-ICSS2
K2G	0	eth1/2	PRU-ICSS0
K2G	1	eth3/4	PRU-ICSS1

When i replace this PRU-ICSS to PRU-ICSS0 in args_mmc boot variable then offload firmware type is selected for PRP mose.

Thank for Reply

Have a nice Day

Dear Biser,

During testing of PRP based on PROCESSOR-SDK-LINUX-AM335X 06_01_00_08 using TMDSICE3359, It is observed that packet latency is more than 1ms for ping test.

what is the issue & how can i resolve this.

Thanks

Hello Sachin,

We assume that the ping test latency is the same question as the post PRP Latency Issue. If so, we will leave this thread about boot variables, and do the latency discussion on the other thread.

Regards,

Nick

Hi Nick,

Ok no issue, we discussed on PRP Latency Issue Thread link in last message & close this thread now.
