Hi,
i am using new BBB-Red industrial grid board…i am trying up the BBB with my carrier card with external power supply which is workling absolutely perfect with my old BBB-black board…
my carrier card with external power supply have 4 isolator Serial digital isolator (Si8422) for 4 UART.
my BBB-Red loaded with with Debian GNU/Linux 7.8 (wheezy) os and made to boot from SDcard and image date is BeagleBoard.org Debian Image 2015-03-01.
lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 7.8 (wheezy)
Release: 7.8
Codename: wheezy
i am trying to troubleshoot i found this
dmesg | grep eth0
[ 5.623106] net eth0: initializing cpsw version 1.12 (0)
[ 5.628425] net eth0: phy found : id is : 0x7c0f1
[ 5.633516] net eth0: phy 4a101000.mdio:03 not found on slave 1
[ 5.665388] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
There is not ethernet connetion, such that i am not able to ping to any IP and i am not able to do ssh to / from the device BBB-red, but this same carrier card with external power supply working fine in BBB-Black which have same OS.
Plz can any any tell me what will be the wrong…???
thank you
