Hi,

I am still seeing the console parameter as ttyS1 and there is some invalid character in bootarg too, please the entire bootargs once, set it as console=ttyS0

"setenv bootargs mem=116M console=ttyS0,115200n8 root=/dev/nfs rw nfsroot=$(nfshost):$(rootpath) ip=dhcp"

Thx,

Hi,

    Thanks for replay

    Still we are facing same problem.

    I tried to change the console parameters ttyS1/ttyo0/ttyS0   and root also instead of mtdblock3 i placed mmcblk0 also

 I am giving setenv commands like this....

EVM # setenv  bootcmd ’dhcp;bootm’
             setenv  bootargs ’console=ttyS0,115200n8 ip=dhcp root=/dev/mtdblock3 rw rootfstype=yaffs2 mem=76M  video=davincifb:vid0=OFF:vid1=OFF:osd0=720x576x16,4050K dm365_imp.oper_mode=0 davinci_capture.device_type=4'

             setenv  serverip <tftp server ip address>
             setenv  bootfile <kernel image>
             boot

        Then board is booting and it is showing like this

Booting kernel from Legacy Image at 80700000 ...
   Image Name:   Linux-2.6.32-rc2-davinci1
   Image Type:   ARM Linux Kernel Image (uncompressed)

Hi,

Is this a custom board ? You mean you enabled low level debug, but did not get a single extra print on the console?

Can you cross verify the image is built for DM365, can test the same uImage on working board if you have.

Are you using prebuilt images from TI. can you flash the same if yes from u-boot to image and try it.

Refer this link too http://processors.wiki.ti.com/index.php/FAQ_for_DaVinci_Linux

Hi,

yes our board is Davinci TMX320DM365 DVEVM..yes we enabled low level debug and we didnt get a single point extra on the console ..

Its just ending at

Uncompressing kernel................................................................done.booting done.

we even tried one downloaded uImage from TI site..Even that is hanging at the same place.

Please help us out..

Thanks

Hi,

Did you flash the same U-boot as provided in the TI package?

Thx,

Hi,

Actually we didnt flashed any u-boot,when we compiled the source code (which we downloaded from ti site) we got uImage.we thought that u-boot may present on TI board (in flash memory).so,we are trying to boot using tftpboot (we placed our uImage under tftpboot folder)via NAND flash...

please help us out.

Thanks,

If you are using kernel 2.6.32 (likely) you can patch it to support "early printk" and possibly get a little bit more on your serial console to figure out what the problem is.

This one applies cleanly to TI's 2.6.32 kernel:  http://paste.ubuntu.com/994256/

-Thanks for reply

Please expand your solution..Where I should the patch to support early printk.....

please help us out.

Thanks,
