Booting kernel issue, hang on "turn off boot console udbg0"

Latest reply on Nov 4, 2014 by Kuowei Hsu

Hi,

 

I using SDK1.6, cpu base p2020 for our costumized board which built "fsl-image-core".

Our uboot file, uImage file, file system and dtb file were all from SDK1.6.


Here are what we setting in u-boot


"consoledev=ttyS0"

"console=$consoledev,$baudrate $othbootargs;"

 

 

Here is the boot log:

turn off boot console udbg0

 

==No more log .........================

 

Q1. Is message "turn off boot console udbg0" is correct behavior??? Why no more messages after that??

 

Q2. Our setting for console is ttyS0, why it changes to udbg0 ???

 

Q2. If this message is right, how should I configure more to see following message ?? Example, turn on ??

 

Thanks for all your help in community.


Regards,

Hsu
