[U-Boot-Users] question about netconsole

[bott at dei.unipd.it]

I'd like to use netconsole to have the possibility of upgrading the  
firmware store on a flash, which has u-boot as bootloader which loads  
and runs linux.

I plan to use tftp to transfer the new firmware images to the board,  
so what I'd like to know if there is any problem using netconsole and  
tftpd together or if it runs the same way as by using a serial port to  
communicate to the board.

Moreover, is it possible to set a password to access u-boot prompt? I  
would like to give the possibility of flashing the device to everybody.

Thanks for you help,

Ottavio

This should work independently from each other.

U-Boot has no conectp of passwords or password management etc.

Please read doc/README.autoboot for  autoboot  configuration  options
which  include support for a (very promitive!) password-like feature,
but please also note that this is working with a  real  console  port
only, i. e. not with netconsole.

Best regards,

Wolfgang Denk

I've been using NetConsole in this manner you describe for the
past several months now. It has been working well -- without
any apparent problems.
