If you looked at the my howto, you will know that is not enough to make
gdbserver work.
In my case, I used the same gdb version on the host side (6.8) as
the one used in the distro. It worked fine. I can imagine if the
versions mismatch, there might be some issues.
Cheers.

Hi,
I don't think increase the HZ would improve the latency performance
significantly in your case.
The standard way to decrease the latency for embedded system is using a
real-time kernel running alongside with uClinux and keeping the
real-time task inside the real-time kernel. Not too sure if

So far, I'm using defaults as supplied by the uclinux-dist
that's supplied by Altera for NIOS2.
Hi Grant,
Have you tried to compile the kernel with low-latency + preemtion option
which is supposed to allow userspace applications to react faster? I
believe that the default is 'server' mode. I
think 'Low-Latency Desktop' mode may give you better performance.
Here is what your linux config o
I've been doing some performance tests comparing eCos and
uClinux on a NIOS2 platform. TCP throughput is comparable
(uClinux does a bit better with only 1 connection&thread, and
eCos does a bit better at 32 connections&threads). But, latency
on uClinux is much worse. The table below shows the tim

Does your gdbserver work decently for dealing with a threaded application ?
I am using uCLinux for non-MMU NIOS2 processor and I was told that the
