The first ROM image provides a port of the CygMonROM monitor, which includes a command-line interface and a GDB remotestub. The second ROM image provides a remote GDB stub only, whichis a minimal environment for downloading and debugging eCos programssolely using GDB.</P><P>eCos, CygMon and the GDB stubs all support the PID fittedwith both ARM7T and ARM9 daughterboards. CygMon and the stubs canbe programmed into either the programmable ROM (U12) or the FLASH(U13). Pre-built forms of both ROM images are provided in the directoryloaders/arm-pid under the root of your eCos installation,along with a tool that will program the stubs into the FLASH memory onthe board. CygMon images are prefixed with the name 'cygmon' andGDB stub ROM images are given the prefix 'gdb_module'.Images may be provided in a number of formats including ELF (.imgextension), binary (.bin extension) and SREC (.srec extension).Note that some unreliability has been experienced in downloadingfiles using Angel 1.00. Angel 1.02 appears to be more robust inthis application.</P><DIVCLASS="SECT2"><H2CLASS="SECT2"><ANAME="AEN3542">Installing the Stubs into FLASH</H2><DIVCLASS="SECT3"><H3CLASS="SECT3"><ANAME="AEN3544">Preparing the Binaries</H3><P>These two binary preparation steps are not strictly necessaryas the eCos distribution ships with pre-compiled binaries in thedirectory loaders/arm-pid relative to the installationroot.</P></DIV><DIVCLASS="SECT3"><H3CLASS="SECT3"><ANAME="AEN3547">Building the ROM images with the eCos Configuration Tool</H3><P></P><OLTYPE="1"><LI><P>Start with a new document - selecting the <SPANCLASS="emphasis"><ICLASS="EMPHASIS">File</I></SPAN>-><SPANCLASS="emphasis"><ICLASS="EMPHASIS">New</I></SPAN> menu item if necessary to do this.</P></LI><LI><P>Choose the <SPANCLASS="emphasis"><ICLASS="EMPHASIS">Build</I></SPAN>-><SPANCLASS="emphasis"><ICLASS="EMPHASIS">Templates</I></SPAN> menu item, and then select the ARM PID hardware.</P></LI><LI><P>While still displaying the <SPANCLASS="emphasis"><ICLASS="EMPHASIS">Build</I></SPAN>-><SPANCLASS="emphasis"><ICLASS="EMPHASIS">Templates</I></SPAN> dialog box, select either the "stubs" package template to builda GDB stub image, or the "cygmon" template to build the CygMon ROMMonitor.
