accommodate cable routing. Choose appropriate international power connection provided) plug power supply into power source. Connect power supply power connector board. EXCIMER will POST (power self test) which will turn status error LEDs. hardware failure will cause both LEDs stay this occurs refer Appendix After successfully completing POST, Excimer will begin executing code from reset vector 0xFFF00100. code executed will copy contents into begin executing MDINK, minimal version Diagnostic Nano-Kernel (DINK). user should MDINK banner prompt terminal emulator screen. MDINK_603e user short interval halt boot process remain MDINK hitting key. From MDINK, download upgrades DINK available from website other software s-record format. user does intervene boot process hitting key, Excimer will proceed branch DINK32 present another banner DINK32 prompt terminal emulator screen. DINK32_603e DINK32 monitor available accept commands. Type This will show list DINK commands. Help will further explain command type help command name. example will explain memory modify command. more information DINK consult DINK Manual.
Part Programming
write program Excimer will need editor, compiler, linker that will generate Motorola format s-records. Several vendors have offered provide limited capability, demonstration versions their compilers linkers distributed with Excimer. Follow directions installing demo software your following example assumes have installed High C/C++ PowerPC Embedded Development Toolset. Limited Evaluation Version this program will operate limit demonstration period) allows only variable declarations function declarations. Also, will only link resulting executable must less than 156KB. These limitations prevent from building DINK large projects still allow very useful minimal evaluation board like Excimer.
Example Program
compile download simple program, type following program into text editor, e.g. NotePad WordPad
example routine turn STATUS void main(void)
MOTOROLA
Minimal PowerPC 603e Evaluation Board
*(char (0x40200000) 0x04; turn status
Save ledon.c text (Many text editors save their format with extra formatting characters that will cause compile fail.) Also, text editors like WordPad Windows will append .txt which must removed before passing compiler. Assuming have installed Metaware compiler your type following window.
hcppc -Hppc603 ledon.c
load program downloadable s-record type following window.
ldppc start_addr=0x70000 ledon.o
named will generated this will download Excimer. Excimer terminal window, DINK32 prompt type following:
<return>
This DINK download command that takes s-record loads into EXCIMER board. Downloading DINK equivalent typing entries into keyboard. fact, text keystrokes DINK commands downloaded easily s-records. terminal emulation program will provide autotype function that permits user select a.hex s-record previously generated download through serial into Excimer. DINK32 prompt returns when download complete. type command program turn

Status Excimer controlled signal Serial UART (National Semiconductor PC1655D Dual Universal Asynchronous Reciever/Transmitter). will turn when this program writes (bit LSB) MODEM Control Register address 0x40200000 Excimer. will remain until disabled another program write, compile, link download until Excimer board reset. does out, debug capabilities Excimer Wiggler used debug your program.
Part Debugging
Debug Excimer supported with following capabilities DINK: Assembly disassembly PowerPC instructions Display registers Display, movement system memory Singlestep continued execution from address Display, setting, removal instruction breakpoints
DINK example ROM-resident debugger. resides copied down execution. resident debuggers often criticized because:
Minimal PowerPC 603e Evaluation Board
MOTOROLA
They take space target system memory They have change (save restore) context application They ineffective debugging boot code that initializes hardware resident debugger They often cannot breakpoints
PowerPC microprocessors provide on-chip debugging logic overcome some these provide other capability without storing code memory having save restore state program. PowerPC on-chip debugging support includes: control ability halt, single step, resume execution address begin execution. Display registers processor resources Display, modify download memory (possibly including chip memory like cache and/or TLBs) Display, setting, removal instruction breakpoints hardware
This capability accessed sending commands common on-chip processor (COP) through JTAG (Joint Test Advision Group IEEE1149.1 standard) interface. connector provided access this Excimer numerous third parties provide software hardware take advantage while debugging code. Excimer includes inexpensive Wiggler JTAG/COP interface from Macraigor Systems, Inc.
Wiggler
Wiggler from Macraigor Systems inexpensive JTAG/COP interface control debug PowerPC Microprocessor though parallel port translates software commands from various debugger vendors such Cygnus, Green Hills, Metaware, Metrowerks, Microtec, Motorola, SDS, Tasking, Wind River that utilize On-Chip Debug (OCD) Application Programming Interface (API). Wiggler supports various Motorola microprocessors including CPU32, MPC5xx, MPC6xx, MPC7xx, MPC8xx, etc. Macraigor provides several different compatible products that perform this function increasing levels performance, functionality, cost. Wiggler least expensive, simplest device provides appropriate level performance capability inexpensive evaluation like Excimer, more serious software hardware development user interested higher capability JTAG/COP interface tools from Macraigor other vendors. third party debugger solutions provided developers Excimer utilize Wiggler interface. Check their documentation. Macraigor Systems provides software application that tests exercises Wiggler that used control processor, examine registers memory, download code, etc. Macraigor application included Excimer instructions loading onto WindowsNT Windows95 described Section 1.2, Wiggler
Installing Wiggler Software
