TDA4VM: tda4 rgmii status problem

user6390135

Part Number: TDA4VM

Hi, experts:

I am now developing our custom board of TAD4VM CPSW9G RGMII1 port with phy dp83867. I am not sure how to do it, so simply changed the phy address in cpsw_appboardutils_j721e_evm.c.

Now I can see the phy 0 live and the state machine can go into Cpsw_handleLinkUp. But it stuck at the first while loop.

I read out the phy registers, linkup and auto negotiation is complete.what is the logic of CPSW_SS_RGMII1_STATUS_REG. Am I missing anything important change?

Hello.

TI EVM also has RGMII connected to same PHY, so changing the PHY address for their board should have been enough.

One thing to try is change the PHY mode to ‘forced’ instead of ‘in-band’.

Please see file: packages/ti/drv/cpsw/examples/cpsw_apputils/V1/cpsw_appboardutils_j721e_evm.c

API: CpswAppBoardUtils_setPhyConfigRgmii

Change: interface->variantType to CPSW_MAC_VARIANT_FORCED

Hello Dave:

Thanks for your help, changing the PHY address is enough, I've solved this problem. Besides, I can ping to ethfw on R5F0-0 through rgmii port now,

but the switchconfig_client.py does not work. Seems that it try to connect port 5555 on R5 but failed. Is it a known issue or I have to change another

configuration?

Hi,

It is expected to work.

Are you entering the IP address of EVM in the GUI?
You can see the IP address in the Ethfw UART logs.
