TMDSCNCD263: AM2634-CC CPSW Ethernet hardware MUX connections.

Hi Hari, 

Q1) Do i need to control MUX via I2C IO Expander?

No, you should not need to control the MUX with the IO Expander.  The select signal is pulled down, which connects input A to output B1.

Which Ethernet SDK example are you trying to run?

Q2) Which is J7(Eth connection 1) in below image?

Regards,

Brennan

Hello Brennan,

Thank you for MUX clarification.

Which Ethernet SDK example are you trying to run?

i'm using MCAL_AM263_09.00.01.

EthApp from mcal.

Q) in which mode timer RTI0C0 is used for delay generation during EthTrcv initialization?

In general Elektrobit uses capture & compare mode for OS timer/counter.

During our initialization of EthTrcv, Trcv is not initialized properly.

I'm able to receive frames but not able to transmit Eth frames.

Do you any points to check, regarding only reception no transmission.

Mcal demo Trcv init values.

During Mcal Demo test Link Indicator always in off mode.

In our configuration 

But in our configuration case it is ON & ORANGE/YELLOW in color.

Above 01 value because of link LED on.

Q) Why it is turning ON in our case & OFF in mcal demo?

Kind regards,

Hari
