1. Linux Note The process for installing the USB2DEMON drivers under Linux is described on the Macraigor web site NOTE The USB2DEMON drivers are not compatible with Windows 95 98 When installing your application make sure you are logged on as ADMINSTRATOR and that you re boot your machine after the installation process 2 2 Install USBZ2DEMON Hardware Once the host software has been installed and your computer has rebooted you can plug the USB2DEMON into any available USB port When you plug in the USB2DEMON for the first time Windows should auto detect it and start the Found New Hardware wizard Allow Windows to install the hardware automatically You will get a notification saying that the Macraigor drivers have not passed Windows logo testing Choose Continue The Found New Hardware wizard should run twice because there are two logical USB devices in the USB2DEMON This installation process will occur the first time a new or different USB2DEMON is connected to the host computer 2 3 Determine Device ID Up to 16 USB2DEMONS can be connected to a single host computer In order to specify which device to connect to your application must select a device number between 0 and 15 To determine which USB2DEMON is assigned to which device number a utility named usbdemon Finder is available If you are using Macraigor applications such as OCD Commander Flash Programmer or J SCAN this utility will have been installed as2. p GND nc 19 20 p GND OR This header uses a pin spacing of 2mm TCK i 1 2 p GND TRST i 3 4 1 TMS SRST i 5 6 p GND TDO o 7 8 p GND TDI i 9 10 p TVcc MIPS EJTAG 2 5 There are many MIPS OCD headers in use This is the one specified by MTI for EJTAG 2 5 TRST 1 1 2 p GND TDI i 3 4 p GND TDO o 5 6 p GND TMS i 7 8 p GND TCK i 9 10 p GND RESET oc 11 12 k key DINT I 13 14 p TVcc Toshiba s MIPS header This header uses a pin spacing of 0 05 TRST i 1 2 p GND TDI i 3 4 p GND TDO o 5 6 p GND TMS i 7 8 p GND TCK i 9 10 ne TVcc p 11 12 nc RESET oc 13 14 ne ne 15 16 nc nc 17 18 nc ne 19 20 nc Phillips MIPS header TRST 1 1 2 p GND TDI i 3 4 p GND TDO o 5 6 p GND TMS i 7 8 p GND TCK i 9 10 p GND RESET oc 11 12 p GND nc 13 14 p GND nc 15 16 p GND nc 17 18 p GND nc 19 20 p GND AMD Elan SC520 This header uses a pin spacing of 2mm GND TCK TMS TDI TDO SRESET AMD Athlon This header uses a pin spacing of 0 05 TVcc GND DBREQ RESET AMD Opteron Geode NX This header uses a pin spacing of 0 05 GND RSVD1 RSVDO DBREQ DBRDY TCK TMS TDI TRST TDO TVcc TVcc KEY

9. therwise indicated RESET or HRESET is an open collector signal from the probe to the target It should directly drive the target processor and not drive power on reset circuits or the like If you are building your own board place the header as close to the processor as possible use short traces of approximately equal length on all clock and data signals Pins are identified by number and type o output from target processor to OCD interface i input to target processor from OCD interface p power pin oc open collector driven from OCD interface either floating or actively held low nc not connected ie not driven nor read by OCD interface k key pin is typically missing from the target board COP pinout for Motorola PowerPC 6xx 7xx 8xxx and IBM PowerPC 6xx and 7xx IBM also refers to this connection as RISC Watch TDO of 1 2 TDI i 3 4 HALTED o 5 6 TCK i 7 8 TMS i 9 10 SRESET i 11 12 HRESET oc 13 14 CKSTP_OUT o 15 16 IBM AMCC 4xx IBM also calls this RISC Watch TDO oj 1 2 TDI i 3 4 HALTED o 5 6 TCK i 7 8 TMS i 9 10 HRESET i 11 12 SRESET oc 13 14 CKSTP_OUT o 15 16 BDM for Motorola MPC8xx MPC5xx nc nc nce nce nce nc QACK TRST TVcc GND GND QACK TRST TVcc GND GND NOTE It is vital that pins 1 and 6 properly reflect the status o
10. y mentioned as well as others refer to Appendix A for a list of common OCD interface pinouts Because there are so many OCD formats each with its own electrical characteristics and pin outs the USB2DEMON can be ordered in several different configurations to match the interface on your target processor In addition the USB2DEMON can be configured with flying leads to support hardware level boundary scan testing and debugging via JTAG 1 3 Available Software for the USB2DEMON There are many debuggers available that support the USB2DEMON as well as various other applications such as Flash memory programmers and general JTAG test utilities See our website for updated lists of Macraigor Systems software applications as well as links to third party partners who support the USB2DEMON Macraigor Systems specializes in Flash memory programming technology and test software and also has free software that is available for the USB2DEMON The free debuggers available from Macraigor Systems include a low level command line debugger called OCD Commander and full GNU toolsets for ARM MIPS PowerPC and XScale All of these tools may be downloaded from our website www macraigor com 2 Installation 2 1 Install Host Software The USB2DEMON can be used with a variety of host debuggers and applications Regardless of what application is used the software must be installed prior to attaching the USB2DEMON to the host computer for the first time
