MN10300 stdeval1 Hardware Setup

The eCos Developer’s Kit package comes with a pair of EPROMs which provide GDB support for the Matsushita MN10300 (AM31) series evaluation board using CygMon, the Cygnus ROM monitor. Images of these EPROMs are also provided at BASE_DIR/loaders/mn10300-stdeval1/cygmon.bin. The LSB EPROM (LROM) is installed to socket IC8 on the board and the MSB EPROM (UROM) is installed to socket IC9. Attention should be paid to the correct orientation of these EPROMs during installation.

The CygMon stubs allows communication with GDB by way of the serial port at connector CN2. 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 standard RS232C serial cable (not a null modem cable). A gender changer may also be required.
