An imageof this EPROM is also provided at loaders/arm-cma230/gdbload.binunder the root of your eCos installation. </P><P>The EPROM is installed to socket U3 on the board. Attentionshould be paid to the correct orientation of the EPROM during installation.</P><P>If you are going to burn a new EPROM using the binary image,be careful to get the byte order correct. It needs to be little-endian,which is usually the default in PC based programmer software.</P><P>If the GDB stub EPROM you burn does not work, try reversingthe byte-order, even if you think you have it the right way around.At least one DOS-based EPROM burner program is known to have thebyte-order upside down.</P><P>The GDB stub in the EPROM allows communication with GDB usingthe serial port at connector P12 (CMA101) or P3 (CMA102). The communication parametersare fixed at 38400 baud, 8 data bits, no parity bit and 1 stop bit(8-N-1). No flow control is employed. Connection to the host computershould be made using a dedicated serial cable as specified in theCogent CMA manual.</P><DIVCLASS="SECT2"><H2CLASS="SECT2"><ANAME="AEN3778">Building the GDB Stub FLASH ROM images</H2><P>Pre-built GDB stubs images are provided in the directory loaders/arm-cma230 relativeto the root of your eCos installation, but here are instructionson how to rebuild them if you should ever need to.</P><P>CygMon images are prefixed with the name 'cygmon' andGDB stub ROM images</P><P>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). </P></DIV><DIVCLASS="SECT2"><H2CLASS="SECT2"><ANAME="AEN3783">Building the GDB Stubs with the eCos Configuration Tool</H2><P></P><OLTYPE="1"><LI><P>1.
