Message: 60331   

I tried to port uClinux kernel to my custom board, have done something as the doc http://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:customizing_for_your_board discribes.

and i did noting to change the kernel configuration except the Blackfin processor option--->system type

the system type was set to my custom board.

then saved and make

but when boot this compiled kernel , the system halt after output    Warning : unable to open an initial console.

what's the problem with my kernel configuration. and where to config the console,how.

thanks.

if you did not correctly update your kernel clock settings to match your hardware, that's a very bad thing and you need to go back and do that

you need to check your uclinux-dist settings and make sure that the console device node is being created in your rootfs image

post the full kernel boot output

which indicates that whatever you're using to generate the final image is doing something wrong.  check your vendor settings as well as vendor makefiles.

cheers !

I found the reason that the BOARD.c ,in this case is pafone.c,did not declare the UART resource .

I added the declare code and the problem resolved.

thank Mike for remind me the console device node
