Hello varun k jayan,

If you didn't configure MAC addresses for FMAN Ethernet ports correctly in u-boot environment, you will encounter this problem. Please configure u-boot environment as the following.

eth10addr=00:e0:0c:00:7a:0a

eth11addr=00:e0:0c:00:7a:0b

eth12addr=00:e0:0c:00:7a:0c

eth13addr=00:e0:0c:00:7a:0d

eth14addr=00:e0:0c:00:7a:0e

eth15addr=00:e0:0c:00:7a:0f

eth1addr=00:e0:0c:00:7a:01

eth2addr=00:e0:0c:00:7a:02

eth3addr=00:e0:0c:00:7a:03

eth4addr=00:e0:0c:00:7a:04

eth5addr=00:e0:0c:00:7a:05

eth6addr=00:e0:0c:00:7a:06

eth7addr=00:e0:0c:00:7a:07

eth8addr=00:e0:0c:00:7a:08

eth9addr=00:e0:0c:00:7a:09

ethaddr=00:e0:0c:00:7a:00

If this doesn't help, please provide u-boot and Kernel booting log, and also provide u-boot environment with "pri" command.

Have a great day,
Yiping

=> at s7=45 s0=0 L1 v1 x4 & c1 E1 Q0

=>syntax error

please help

Hello varun k jayan,

First please run "pri" command under u-boot prompt to show your u-boot environment, and check whether the some MAC address configurations are missed.

Please configure MAC address with the following commands.

=>setenv ethaddr 00:e0:0c:00:38:00

=>setenv eth1addr 00:e0:0c:00:38:01

Configure the Ethernet port which you are using, for example FM1@DTSEC1

=>setenv ethact FM1@DTSEC1

You could configure ramboot as the following

=>setenv ramboot 'setenv bootargs root=/dev/ram rw console=ttyS0,115200;tftp 2000000 <ramdiskfile>;tftp 1000000 <uImage>;tftp c00000 <dtsfile>;bootm 1000000 2000000 c00000'

=>run c00000

I suggest you start with Linux SDK user manual provided in the SOURCE ISO first.

Have a great day,
Yiping
