Hello,

You can refer this link processors.wiki.ti.com/.../DaVinci_(ARM9)_PSP_Releases
and if you click on downloads arago-project.org/.../
you can find images for DM6446.

Cheers,

Hi Parwath,
As Prabhakar replied, have you tried the pre-built images of DM6446 ?
arago-project.org/.../

Here you can find all the required pre-built images (u-boot, rootfs, ramdisk, kernel image etc.,) can be found.

You can check the configs in "u-boot/include/configs" for DM6446 EVM.
Like "davinci_dm6446evm.h"

Command to configure and build u-boot:
export ARCH=arm
export CROSS_COMPILE=arm-arago-linux-gnueabi-
make davinci_dm6446evm_config
make all

Please make sure that you have proper kernel by booting the kernel from NFS.

setenv bootcmd 'tftpboot 0x80700000 uImage;bootm'

setenv bootargs 'console=ttyS0,115200n8 ip=dhcp nfsroot=192.168.1.145:/home/titus/filesystem_dm6446 root=/dev/nfs rw rootwait'

Please provide the log when you do NFS boot.
