thanks Deepak:
I have configed kernel by the command :
make ARCH=arm CROSS_COMPILE=arm_v5t_le- davinci_dm355_defconfig
make ARCH=arm CROSS_COMPILE=arm_v5t_le- uImage
use the default configs for dm355,the kernel can't been boot up,I have
Enabled kernel hacking->kernel debuging->low level debug functions.
I don't think the low level debug can do anything for your from kernel
decompression, and until the console is registered.
Try to apply the attached printascii hack
Jean-philippe François
the same result i goted! the envirment is:
software:DaVinciLSP_02_00_00_110 ,mvltools5_0_0801921
hardware: dm355 evm
and resut is as:
DM355 EVM # tftpboot

It stoped here for ever! it seems no printed kernel information only
uboot prints,I have doubled where the serial configs have errors,I have
checked the bootargs whick can been used well for the uImage that comes
with DVSDK.
setenv bootargs console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs
nfsroot=10.0.0.89:/opt/montavista/pro/devkit/arm/v5t_le/target/,
nolock mem=116M video=davincifb:vid0=720x576x16,2500K:vid1=720x576x16, 2500K:osd0=720x576x16,2025K davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=$(videostd)
so it is not the bootargs error i think! serial driver error? board
config driver error? It amazed me so far!

Dear *zuowenping*
do make menuconfig
Enable kernel hacking->kernel debuging->low level debug functions
and compile the kernel and post the kernel output here

Just want to make sure I understand, you can boot the board with the
binary that comes with DVSDK, but you can not boot the board with the
binary generated by following the "Getting Started Guide"
If that is the case, what are the commands you used to configure and
build the kernel and what error did you see during boot up?
Regards,
Steve
