An image of this EPROM is also provided at loaders/arm-cma230/gdbload.bin under the root of your eCos installation. </P ><P >The EPROM is installed to socket U3 on the board. Attention should 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 reversing the 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 the byte-order upside down.</P ><P >The GDB stub in the EPROM allows communication with GDB using the serial port at connector P12 (CMA101) or P3 (CMA102). The communication parameters are 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 computer should be made using a dedicated serial cable as specified in the Cogent CMA manual.</P ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="AEN3778">Building the GDB Stub FLASH ROM images</H2 ><P >Pre-built GDB stubs images are provided in the directory loaders/arm-cma230 relative to the root of your eCos installation, but here are instructions on how to rebuild them if you should ever need to.</P ><P >CygMon images are prefixed with the name 'cygmon' and GDB stub ROM images</P ><P >are given the prefix 'gdb_module'.
