Coldfire Computer Final Presentation Josh Hudgins Randy Jedlicka Drew Larson Project Staff:

Abstract The central objective for this project is to produce a better lab for CPSC 462 students. With this in mind, several labs must be laid out as tasks for these students to perform. In summary, the main tasks that must be accomplished to produce the ColdFire microcomputer, for these labs, are the following:  Design Modification/Inspection of previous PROTEL layouts produced by Legendary Group 5  Production of PCB by 3 rd party manufacturer  Assemblage of components to completed PCB  Programming of Flash Memory with “monitor” program via JTAG connector  Porting of VxWorks OS to Flash Memory

Objectives & Deliverables MAIN GOAL: Develop working computer using the Motorola Coldfire Processor Evaluate the current status of the previously existing hardware designs Redesign (if necessary) Complete PCB layout with Protel Send designs off to have manufacturer fabricate PCB

Objectives & Deliverables (cont.) Mount all components onto board Port dBug monitor to Flash ROM Port VxWorks to Flash ROM Test Completed design with Dumb Terminal Rewrite Labs for CPSC 462

Evaluate/Redesign existing hardware designs in Protel Component change –Flash: AM29F040 Vs NEC EEPROM Schematic Corrections –Power line connected to ground? –New lines for new flash

Full PCB Block Schematic

PCB Layout Completely redone –Board dimension –Layers of the board –Component placement –Trace routing

CAD PCB Layout

PCB fabrication AP circuits required files: –Gerber Top and Bottom Layer, NC Drill, Drill Tool Size, and Aperture Table Manufacturing delays –Short on board from 2 holes –Free drill bits

Mounting components on PCB 160-pin processor socket The 96-pin Connector The BDM Connector Resistors and Capacitors Power ports The Under Voltage Sensor

Completed PCB

dBug Monitor Development Environment Win32 and SunOS versions Directory Structure Use of Makefiles Problematic Issues –Compiler Problems (EGCS1.1.1) –Makefile Issues –Board Specific Matters

dBug Monitor Development Environment (cont) Board Specific Monitor Program –Adapted MCF5206AN Compiled Using Make Files

Write dBug Monitor Program

dBug Monitor Program Port into memory by use of JTAG

Port dBug Monitor to Flash JTAG Boundary Scan Technology –Specific Files Needed Protel - Netlist Motorola - BSDL –Converted to EDIF (Electronic Design Interchange Format) Component File Sel File - Directory Structure

Port dBug Monitor to Flash Installation Problems –WindowsNT / Windows2000 –Device Recognition Incompatible Protel file Error: No BST devices in design

Port dBug Monitor to Flash (Results) Placed DBUG monitor program in JBC3710 Performed integrity checks of Monitor program –Successful Continuing to resolve JTAG programming issues with Technical Support Personnel

VxWorks Operating System The BSP for the SBC5206 board sent to us by Wind River Unattempted: The OS will be ported to the board via serial port and dBug monitor program

Rewrite Labs for CPSC 462 Adapted labs for use with our board –Updated addressing information –Updated components and pinouts –Deleted unusable labs Did not get to attempt these labs

Proposed Project Schedule

Project Schedule Followed

Conclusion Completed Objectives: –Printed Circuit Board –Board Specific Monitor Program –Lab Manual Partially Complete Objectives: –Port the Monitor to Flash Uncompleted Objectives: –Port the Monitor to the Flash –Port VxWorks to the Flash
