what should i see in ngw100's serial port in the first boot (using buildroot)? - 2012-09-22 23:06:00

Hi, is just that i built buildroot successfully, and i put the files in the SD card (the ones from the root folder), but i dont see anything in the serial port (using minicom), i don't know what to do, if someone could help me it would be really great because i need to make this work as soon as possible, thanks in advanced. 

Best Regards.

It's a long time since I worked with an NGW100 but I'd expect the first
thing you see to be the U-boot prompt.  Are you getting that ?  I think
you should be, because ISTR that the boards come with U-boot already
installed.

First thing worth doing would be checking your serial link.  Do you have
a straight-through cable when you need a crossover, or vice versa ?
Have you configured your terminal emulator correctly (start with
115200 8N1 and disable modem control and flow control until you can see
characters being exchanged) ?

If you're sure the serial link is OK, if you can talk to other serial
devices OK, then perhaps you need to load the U-boot that you build
in your toolchain onto the board first.  Atmel's pages have loads of
information on doing this.
