Freescale Semiconductor, Inc. D:\TECD-SPO\Documentation\MPC564EVB\mpc564evb_3_Firmware_V1.fm 4/1/03 Freescale Semiconductor, Inc... Chapter 3 Using the Monitor/Debug Firmware The MPC564EVB single board computer has a resident firmware package that provides a self-contained programming and operating environment. The firmware, named dBUG, provides the user with monitor/debug interface, inline assembler and disassembly, program download, register and memory manipulation, and I/O control functions.
Freescale Semiconductor, Inc. Operational Procedure Most commands can be recognized by using an abbreviated name. For instance, entering “h” is the same as entering “help”. Thus, it is not necessary to type the entire command name. The commands DI, GO, MD, STEP and TRACE are used repeatedly when debugging. dBUG recognizes this and allows for repeated execution of these commands with minimal typing. After a command is entered, simply press or to invoke the command again.
Freescale Semiconductor, Inc. Operational Procedure • Freescale Semiconductor, Inc... • Make sure the IP bit is set (switch 5 ON in MAP_SW). This will cause the board to boot out of external flash (where the dBUG code resides). Turn power on to the board. Chapter 3.

The -a option adds a symbol name and its value into the symbol table. The -r option removes a symbol name from the table. Freescale Semiconductor, Inc...
Freescale Semiconductor, Inc. Commands TRACE Usage: Trace Into TRACE The TRACE command allows single-instruction execution. If num is provided, then num instructions are executed before control is handed back to dBUG. The value for num is a decimal number. The TRACE command sets bits in the processors’ supervisor registers to achieve single-instruction execution, and the target code executed. Control returns to dBUG after a single-instruction execution of the target code.
Freescale Semiconductor, Inc. Commands VERSION Usage: Display dBUG Version VERSION The VERSION command displays the version information for dBUG. The dBUG version, build number and build date are all given. The version number is separated by a decimal, for example, “v 2b.1c.1a”.

Freescale Semiconductor, Inc. Freescale Semiconductor, Inc... Appendix B Configuring dBUG for Network Downloads The dBUG module has the ability to perform downloads over an Ethernet network using the Trivial File Transfer Protocol, TFTP (NOTE: this requires a TFTP server to be running on the host attached to the board). Prior to using this feature, several parameters are required for network downloads to occur. The information that is required and the steps for configuring dBUG are described below. B.
Freescale Semiconductor, Inc. Troubleshooting Network Problems set gateway set netmask set ethaddr For example, the TFTP server is named ‘santafe’ and has IP address 123.45.67.1. The board is assigned the IP address of 123.45.68.15. The gateway IP address is 123.45.68.250, and the netmask is 255.255.255.0. The ethaddr address is chosen arbitrarily and is unique. The commands to dBUG are: Freescale Semiconductor, Inc... set client 123.45.68.15 set server 123.45.67.
Freescale Semiconductor, Inc. Troubleshooting Network Problems fail, and probably other severe network problems. Make certain the client IP address is unique for the board. Check for proper insertion or connection of the network cable. Is the status LED lit indicating that network traffic is present? Check for proper configuration and operation of the TFTP server. Most Unix workstations can execute a command named ‘tftp’ which can be used to connect to the TFTP server as well.
