TDA4VM: Ethernet All RX packets are dropped

Prashant Kumthekar

Part Number: TDA4VM

We have integrated CPSW9G driver into linux A72 core, we have used SJA1105 switch.
We are seeing all RX packets are getting drop:

Hi Prashant,

Can you provide the following information:

The speed and duplexity of the link
Output of `ethtool eth0`
Can you confirm that you have done all the things mentioned here.
Can you provide the output of the command "ethtool -S eth0" before and after a ping is run for some time.

Regards,
Tanmay

Hi Prashant,

The logs you have attached are very clean, they do not have any drops. There are few observations from my side though, please explain these if you can:

The Rx traffic seems to be much more than the Tx traffic
There are additional statistics present in the ethtool log.
- Have you added these?
- These seem to be from the switch. Can you confirm this?

Apart from this, can you provide details for the following:

Are you using RGMII mode?
- If yes, what are the delay configuration set for both switch and CPSW?
Can you provide the entire linux boot log.

The speed and duplexity of the link
Output of `ethtool eth0`
- Can you also provide answers to above question
Which kernel version and base commit-id (from ti-linux-kernal repo) are you working with?

Regards,
Tanmay
