TDA4VM: Linux CPSW9g network node

Part Number: TDA4VM


Hi,

using the PSDK LINUX and RTOS v7.1 with the default filesystem and kernel, I am trying to bring-up the network interface for the CPSW9g. Currently only the CPSW2g network interface is working, which is eth0 on MCU ENET port on the EVM.

But the board has also the 4x Ethernet port board connected with the QSGMII PHY, which is connected on the CPSW9g. 

The ethernet switch firmware is loading correctly

root@j7-evm:/sys/class/remoteproc/remoteproc4# echo "start" > state
[ 9238.065327] remoteproc remoteproc4: powering up 5c00000.r5f

[ 9238.109038] remoteproc remoteproc4: remote processor 5c00000.r5f is now up

The virtual MAC driver is loading

j721e_cpsw_virt_mac   327680  0

The rpmsg driver is also loading

rpmsg_kdrv_switch     262144  0

Should we not see something like an eth1 for the CPSW9g?

Thanks!

  • Hi Gunter,

    How are you booting ? Is it SD Card ? How did you create the image ? Please share the steps

    Also, what is the SDK version you are using ?

    If you create a bootable SD card through SDK scripts, it should work out of box

    Regards
