I am having P5040ds processor and having a marvel switch on my board through MAC-MAC SGMII connection. We are having some issue in communication between processor and switch.
The processor is configured on 1G fixed link SGMII mode and same setting is done on switch.
To debug the issue, we need to run PRBS on processor fm1-gb0 port, kindly provide related documentation / registers to do the same.
Also Is there any procedure to enable remote loopback on fm1-gb0 MAC?
P5040 does not have a built in PRBS generation and checking. but customer can use an external loop card/board (connecting the RX to TX) and generate any test sequence (including a test that would be similar/same as pseudorandom binary sequence) and check it in the test SW.
Hello,
1. Is there support for remote MAC loopback for dTSEC ?
2. In the DPAARM , it is mentioned that "Carrier extend symbols in full duplex mode are not supported", does it mean that Carrier extend symbol is supported in half duplex mode?
3. No register could be found in RM as well as DPAARM for carrier extension. Do let us know the register configuration to enable/disable the carrier extend symbol.

Ram
Any update on this query would be appreciated.
