linux-c6x: eth0 is unstable

Murat Tekalp

hi, all:

My current linux-c6x is downloaded from the git server master, and it has added many more

features than the 2.0.0.63 version.

I found one bug in this version: when I boot from NAND, first I trun off the eth0 by

ifconfig eth0 down

then I turn on the eth0 by

ifconfig eth0 on

now the system doesn't response, the serial console didn't display any char.

when I operate on eth1, it doesn't behave like this and runs ok

when I run the old version 2.0.0.63 version, it runs ok and doesn't have this bug.

So I think there is a bug in this version.

Can anyone give some advice?

Hi, Murat,

We may have overlooked, and need to revisit this area. Eth1 does not show the issue could because it is not configured with a PHY.

Hi, Rex:

Thanks for reply.

We have designed a board with 2 phy. When we turn down eth1 and turn it up, it doesn't

cause crash, however eth0 causes.
