>eCos comes with two ROM images that provide GDB support for
|
|
the ARM PID board. The first ROM image provides a port of the CygMon
|
|
ROM monitor, which includes a command-line interface and a GDB remote
|
|
stub. The second ROM image provides a remote GDB stub only, which
|
|
is a minimal environment for downloading and debugging eCos programs
|
|
solely using GDB.</P
|
|
><P
|
|
>eCos, CygMon and the GDB stubs all support the PID fitted
|
|
with both ARM7T and ARM9 daughterboards. CygMon and the stubs can
|
|
be programmed into either the programmable ROM (U12) or the FLASH
|
|
(U13). Pre-built forms of both ROM images are provided in the directory
|
|
loaders/arm-pid under the root of your eCos installation,
|
|
along with a tool that will program the stubs into the FLASH memory on
|
|
the board. CygMon images are prefixed with the name 'cygmon' and
|
|
GDB stub ROM images are given the prefix 'gdb_module'.
|
|
Images may be provided in a number of formats including ELF (.img
|
|
extension), binary (.bin extension) and SREC (.srec extension).
|
|
Note that some unreliability has been experienced in downloading
|
|
files using Angel 1.00. Angel 1.02 appears to be more robust in
|
|
this application.</P
