Other Parts Discussed in Thread: DM388

Hi,

We had developed DM388 based IP Camera. (IPNC RDK 3.8, Linux kernel 2.6.37)

DM388 Connected with LAN8700 Phy ic via emac0 port. Ethernet is working fine and there is no problem in connectivity.

Ethernet link eth0 is not come up automatically so in our custom init script is write following statement.

ifconfig eth0 192.168.102.126

sleep 1

ifconfig eth0 down

sleep 1

ifconfig eth0 up

But some times while doing ethernet link down it stuck up and control not come back. This issue is rarely come. This will stop booting and again power cycle is require.

Is there any patch for this?

Hi Kunjal,

The problem which you observe is not known. Therefore should make deep debugging starting with conditions when it appears. Also I suggest you add printing of debug messages in the driver to localize the function when the stuck up appears.
