  S3C2440 RISC MICROPROCESSOR SJF2440 USER’S GUIDE1 S ECJTAG FLASH(SJF) USER’S GUIDE(PRELIMINARY) DATE:SEPTEMBER 26, 2003   SJF2440 can program SMDK2440 flash memory (K9S1208,Intel E28F128,AMD29LV800BB) through JTAG port andread/write data from/to a specified address. SJF2440 VERSION HISTORY   Version Description 0.1 - K9S1208 programming is supported.- AMD 29LV800BB programming is supported.- Intel E28F128 StrataFlash programming is supported.- External peripherals (PD6710,CS8900A and etc) read/write is supported .  SJF2440 USER’S GUIDE S3C2440 RISC MICROPROCESSOR2 INSTALLING GIVEIO.SYS  In windows NT/2000/XP, any application can’t access the I/O such as the parallel port. So, GIVEIO.SYS enablesSJF.exe to access the parallel port without any memory fault. In windows 95/98, GIVEIO.SYS isn’t needed.For Windows* 2000, use the following procedure:1) Login as administrator2) Copy the giveio.sys file to %systemroot%\system32\drivers.3) Choose Control Panel, and choose Add/Remove Hardware.4) Select 'Add/Troubleshoot a device'5) Select 'Add a new device' and choose Next, and select 'No, I want to select the hardware from a list'6) Select Other devices and choose 'Have Disk...'.7) Choose 'Browse...', locate the folder where giveio.inf file.8) Complete the remained process.For Windows* NT, use the following procedure:1) Login as administrator.2) Open a DOS command window.3) Copy giveio.sys to %systemroot%\system32\drivers.4) Install the driver using the instdrv utility specifying the driver name and the FULL PATH NAME to the giveio.sysfile. instdrv giveio c:\winnt\system32\drivers\giveio.sys 5) To enable the driver to start automatically each time you boot, use the following procedure:- Choose Settings and choose Control Panel.- Choose Devices, select giveio from the list, and choose Startup.- Select Startup Type Automatic from the Device menu. INSTALLING JTAG DONGLE The JTAG dongle is JTAG programming cable, which is connected to the PC parallel port.Because we can’t get 74AHC541, 74LS541 is used instead. So, some circuit is modified from the srcinal donglecircuit fromhttp://www.lart.tudelft.nl/projects/jtag/ . (This dongle can be also used for SA-1110.)It’s recommended to refer to the srcinal JTAG dongle circuit. If you can’t get 74AHC541, refer to our schematiccircuit. If you are using our schematic, the cable length should not be longer than 1m.  S3C2440 RISC MICROPROCESSOR SJF2440 USER’S GUIDE   3 Holly Gates' Schematics for the JTAG Dongle (http://www.lart.tudelft.nl/projects/jtag/ ) Modified Schematic for the JTAG Dongle Circuit Using 74LS541  SJF2440 USER’S GUIDE S3C2440 RISC MICROPROCESSOR4 HARDWARE INTERFACE FOR FLASH PROGRAMMING USING SJF2440 When you program flash memory using SJF2440, you should consider following hardware interface.
