Ethernet (CPSW) stops working after a short while in DM385 with MII KSZ8001L and kernel 2.6.37 and NFSv2: NETDEV WATCHDOG: eth0 (cpsw): transmit queue 0 timed out

Hi Gadi,

Gadi Bergman said:

We are developing a board based on Appro DM388 IPNC, but with an MII PHY component: KSZ8001L because the original could not be ordered.

For porting custom ethernet PHY in u-boot/linux kernel, make sure you are aligned with the below wiki page:

Gadi Bergman said:

U-Boot works well in downloading files from the ethernet.

Can you provide full boot up log of the u-boot? Can you also try command in u-boot, commands like "dhcp", "ping", "tftpboot", "bootp", are these commands work fine?

Gadi Bergman said:

The kernel, 2.6.37, however, starts up well and connects with NFS to the PC, but very soon stops working randomly and after a while we see:

nfs: server 10.X.X.X not responding, still trying
nfs: server 10.X.X.X not responding, still trying

Can you provide us the whole linux kernel boot up log, not only the last part of it?

Regards,
Pavel

Hi Pavel,

Thank you for the porting guide link. I have added the Micrel Phy driver and it seemed to have some effect, at least on the kernel logs, but it did not solve the issue, but I think I can redefine the issue as - ethernet stops working after a period of about 15-20 seconds of inactivity, at least it seems so now with the current configuration. I don't see the NETDEV WATCHDOG any more though.

From your cmd line I see you are using static ip instead of dhcp. Can you interrupt the u-boot countdown, enter into the u-boot and print the u-boot environments, I want to check if your u-boot environments are correct for static ip configuration.

u-boot#printenv

Can you also try to pass ip 10.30.40.21 instead of 10.0.4.24 in the boot args, is there any deference?

See the below wiki pages for the correct configuration regarding static ip usage:

Pavel

No, there was no difference.

This might be error in your host machine (i.e. desktop PC) NFS server configuration. Can you try to establish stable ethernet connection between your host machine and any TI EVM (DM38x, DM814x, DM816x)? Note that in DM814x EZSDK we have a special script setup-targetfs-nfs.sh to install and configure properly the NFS server to the host machine. You can install the latest DM814x EZSDK and have a look.

Check also if connecting your custom board to the host machine directly (without router/switch/hub between) will resolve. Check also if there will be any improvement if you switch to 100Mbps and/or 10Mbps mode, remove gigabit 1Gbps support from the CPSW driver (gigabit_en=0).

Ensure that both u-boot & uImage is set to follow same network parameters (static or dhcp,  MAC address, IP address, gateways, netmaks, etc...).
