starting it. You then need to attach to it. This is similar to attaching GDB to
a running process. As your target hardware is remote, that is not on the host
machine running GDB you need to use the `target remote` command to attach to the
"remote process" or you target hardware. When attached GDB presents you with the
halted state of your target and you are now ready to set breakpoints, inspect
variables and continue executing.
With an embedded GDB session the `load` command is sometimes used. This is an
extra step to download the executable image to your remote target. GDB needs to
be attached to your target to do this. Think of this step as filling the memory
with the code and initialised data.

`arm-rtems5` and `rtems_bsp` is the BSP, eg `beagleboneblack`.
The RSB extracts the needed options from pkg-config ...
%define rtems_bsp_includes -I%{_includedir}
%define rtems_bsp_ccflags %{pkgconfig ccflags %{_host}-%{rtems_bsp}}
%define rtems_bsp_cflags %{pkgconfig cflags %{_host}-%{rtems_bsp}}
ARMs low
number registers are arguments or local scratch registers when calling C code.
The call to `bsp_start_arm_drop_hyp_mode` trashes r3.
I will post a patch to devel with a tested fix ...

The other little wobble is the build stuff is still in the old tree. As a result
you will not find any build stuff under `bsps`.

reload so the latency of the timer interrupt is not a factor in the overall
stability of the tick period. If software needs to reload the timer then the
priority can be a factor.

RTEMS supports termios for UART communications. All you need is a driver for
your hardware.

I understand. Feel free to ask and I can try and answer. Have you seen ...

various board directories hold the ps7_init file generated for that specific
hardware. This means u-boot and the Xilinx SDK boot.bin are consistent in how
the hardware is set up.

The RSB can build lwIP (net/lwip). I have not used it or know anything about it.

There is no trace call to get or read. Maybe add a get/read trace as well.
The RAM disk also has trace in the code which can be enabled by editing the
