Booting issues on DM368

Hi Mayank,

>>>IP-Config: No network devices available.

In your boot log, i can see that there is no network interface identified. This is the reason why NFS is not mounting. I think the user guide refers to use kernel defconfig which is in debug mode (defconfig_dbg). In the standard uImage that is provided in IPNC Ref Design, we disable the network interface during boot up so that we can boot faster. We enable the network interface in the application startup.

In debug mode of the kernel defconfig, we keep the network interface enabled by default.

For your question on the right environment for testing your algorithms, the best option is to have the NFS system mounted on the target. This is the fastest way, you can get your algorithms validated.

Regards,

Anshuman

Hi,

My printenv is as follows:

bootdelay=4
baudrate=115200
setboot=setenv bootargs $(bootargs)
bootamd=nboot 0x80700000 0 0x500000;bootm

and i have build new uimage in debug mode:

tftpboot 0x80700000 uImage_ipnc_DM368_IMX036
nand erase 0x500000 0x200000
nand write 0x80700000 0x500000 0x200000
setenv bootargs'console=ttyS1,115200n8 noinitrd rw root=/dev/nfs nfsroot=192.168.1.21:/home/mayank/DM36x/ipnc/target/filesys,nolock mem=48M ip=dhcp'
setenv eth '00:0C:0C:A0:07:Ea'

and after doing saveenv mode and booting the board i am getting the following output:
