CCS/AM5718: PRU-EMAC Loopback example

Part Number: AM5718
Other Parts Discussed in Thread: TMDXIDK5718

Tool/software: Code Composer Studio

Hi,

I am using TMDXIDK5718 evaluation kit for exploring PRU-EMAC.I am new in this area.
I have installed latest SDK(pdk_am57xx_1_0_13).
Then i have loaded the example ICSS_EMAC_BasicExample_idkAM571x_wSoCFile_armTestproject,(.out file) in cortexA15,in Tera Term(serial port) console showing
"ICSS_EMAC_testTaskPruss1: Waiting for PRU2 Test to complete before testing PRU1".
I have loopbacked the PRU2-ETH0 and PRU2-ETH1 and load PRU with an output file from and load PRU with an output file from ("C:\ti\pdk_am57xx_1_0_13\packages\ti\binary\icss_dualemac\obj\am571x\a15_0\REV2\pru_0"

Please suggest the procedure for doing this experiment

Hi Satheesh,

>>loopbacked the PRU2-ETH0 and PRU2-ETH1.
The loopback test actually loopbacks the packets from sending port to its own receiving port, do you use a Ethernet loopback jack&plug to loopback?

You don't need to manually load PRU image, which has been loaded by the application self.

Garrett

Hi Garrett

Thank you very much

i have shorted (Tx+ ,Rx+) and (Tx- ,Rx- ) line in the Ethernet cable and connected to PRU2 ETH0 .when i run the project,console showing following print

ICSS_EMAC_testTaskPruss1: Waiting for PRU2 Test to complete before testing PRU1
ICSS_EmacTxPacket: returned error with invalid queue number, expected Result
ICSS_EMAC_testTaskPruss1(PRU2 ETH0): received pkt: 2

When i connect same cable in PRU2 ETH1,console showing following print

ICSS_EMAC_testTaskPruss1: Waiting for PRU2 Test to complete before testing PRU1
ICSS_EMAC_testTaskPruss2: LINK IS DOWN, pluggin loopback cable for PRU2 ETH0

Satheesh,

Can you try to have both PRU1 and PRU2 with loopback adapters connected and check the result?
Something like this - www.amazon.com/.../ref=sr_1_2

Hi Garrett

Thank you for your great support

I have connected two loopback cable connector(not the adapter you mentioned, I am trying to procure the adaptor).But with previous setup(two self loopback cables for two PRUs(PRU2 ETH0 and PRU2 ETH1) .I am getting the following console print

Hi Satheesh,

Were you able to get the loopback adapter and successfully run the example? Can we close the thread?

Hi Garrett

No.

same error is coming.

can I run the example given in the diag directory(which is the non RTOS better to understand)

C:\ti\pdk_am57xx_1_0_13\packages\ti\board\diag\icss_emac

Satheesh,

Which error were you referring to?

>>ICSS_EmacTxPacket: returned error with invalid queue number, expected Result

This is the test case with invalid queue number and the printouts are 'expected Result'.

Hi Garrett

Thank you for your great support

you mean PRU2 ETH0 working correctly. what about PRU2 ETH1. I think both PRU in loopbacked mode.

can I run the example given in the diag directory(which is the non RTOS)

C:\ti\pdk_am57xx_1_0_13\packages\ti\board\diag\icss_emac

Satheesh,

Yes, you can try the diag code to check if it passes.

If you have loopback adapter connected well, both ETH0 and ETH1 should pass the loopback test without issue.

Garrett

Hi Garrett

Thank you for your support

I was able to run the example code given by TI as such.

It appears that the issue raised by me was related to installation,

as of now the code is working fine. So the issue is close from my side.
