i.MX53 SABRE Ubuntu Boot up time long because of DHCP timeout

[kriszawada]

Hello,

When I am booting up the i.MX53 SABRE tablet with Ubuntu 10.04 LTS I am noticing that most of delay during boot up is because of sending client DHCP request and waiting for the timeout to expire.  The exact message is (also see attachment):

Sending DHCP requests ...... timed out!

IP-Config: Reopening network devices...

eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=0:00, irq=-1)

Sending DHCP requests ...... timed out!

The boot time takes about 3 minutes 26 seconds.  Majority of the time, about 2 minutes is because of the DHCP timeout.  How can I modify this timeout to be on the order of 5-10 seconds instead of two minutes?

Sincerely,

Kris

Hi Kris,

                      You can try with this boot loader arguments.

                         setenv ip_method off

Thanks & Regards,

Maybe you could added args "ip=none" in bootloader.

Bypass this process in booting stage

I hope this can help you.

Hello Aaron,

Would you be able to tell me where this exactly exists in the bootloader?  I have not done this before.

Sincerely,

hello ,  Kris

i think you could be find it in u-boot-2999.08/include/configs/mx53_{ard,evk,smd}.h

#define CONFIG_EXTRA_ENV_SETTINGS \
...
ip=dhcp ..
... \

You could see detail about "Kernel Boot Parameters" in i.mx53 linux BSP release notes doc

thanks~
