Redboot communicates via the UART but GDB does not? It
could be either one of two things:
1) Problem with Redboot build.
2) Problem with Host machine.
Most likely it will be 2. What Host machine are you using
to communicate to the target? Are you using Cygwin?
First I would make sure that the serial device you are
using is correct. If you are using CygWin it could be that
the serial device has a different name, like /dev/com1.
If you are using Insight 6.1, the default COMX in its
menu might not refer to the correct serial device and it
might give you some IOCTL error.
Second I would make sure that you are using the correct
communication settings.

Dear eCos discussers,
I built a RedBoot[ROM] version to my board. My board
uses S3C4510B, and is similar with SNDS100. So I chosed
SNDS100 template, and modified memory bank settings for
the difference on my board.
The problem is that, now, I can use command line
interface via UART0/UART1 to talk with RedBoot. And even
can use GDB debug via networking channel. But when I try
using GDB to connect RedBoot via UART0/UART1, it never
succeed, times out.
What on earth the problem is? Any other options I
should set?
Anyone could give me suggestions?
Many many thanks.
