High boot up time for DM816x

Hi, I am working on DM816x Netra platform, I am using booting the board from NFS.

And I am using following boot args:

mmc init

setenv nfsserver 10.1.115.172

setenv bootargs 'console=ttyO2,115200n8 root=/dev/nfs nfsroot=10.1.115.172:/u/users/nfspt/hoseo_Netra_NFS rw rootfstype=ext3 earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=50M ti816xfb.vram=0:16M,1:16M,2:6M rootdelay=2 mem=364M ip=10.1.115.45'

fatload mmc 1 0x80000000 uImage

bootm 0x80000000

But the board boot-up time is very high it will take around 5mis!!

Is there any way/setting which will enable fast boot.

With Regards,

Ramakrishna Deshpande

    Hello,

    Your board boots up for 5 minutes? That is definitely not normal. My board board boots for around 30 sec, from a SD card though. The reason for your slow boot could be various. Try to boot from SD card. How is the speed now? If it is OK, then probably it is something related to the networking. Track the log and try to see where is the time mainly spent and let me know.

    Ramakrishna,

    NFS is generally slow. But 5 mins is too much I guess. If optimized properly, DM816x can boot the kernel and mount the file-system in less than a second from reset.

    As Vladimir suggested, have you tried different options like SD/MMC NAND etc?
