INTRODUCTION EeRom-8U ROM Emulator is aimed at developers who focus on making ROM based programs and data including embedded systems, BIOS, video games, robotics, printer drivers, graphic controller, postscript interpreters, character font libraries, and other ROM based application. In general, the emulator is used during program and data developing period to eliminate the frustration of repeated EPROM burn-erase cycles. EeRom-8U ROM Emulator easily plugs in place of the ROM through the emulator's target adapter. Other ROM Emulators can emulate only EPROM. But EeRom-8U ROM Emulator can emulate many types of memories (EPROM, Flash-ROM, EEPROM, NVRAM) currently used. So EeRom-8U ROM Emulator can be called a "memory emulator". Also EeRom-8U can properly operate with user's board using 8bit/16bit/32bit data bus. EeRom-8U ROM Emulator adopts USB interface. This helps the user to have faster communication speed than the parallel port. From this, the user can enormously reduce the developing time and adopt high speed SRAM(12ns) for matching well with high speed RISC and CISC CPU. Therefore both professional and novice program developers will find that EeRom-8U ROM Emulator can be an exceptional valuable tool. < The Characteristics of EeRom-8U > High speed USB interface (Supports Plug & Play) 1M Byte (8M bit) / sec download speed Supports 8bit data bus by itself Uses 1MB high speed memory for proper emulation : 12ns high speed SRAM Supports EeRom-8U without outside electric power supply Convenient software environment: supports Windows /98/ME/2000/XP Supports hex (Intel/Motorola type), binary file format Safety circuit against inverse insertion www.eetools.com -6- EeRom-8U User's Guide II.

The basic project name of this program is erusb.erp. When program performs for the first time and if project is created, you need to change another project name to different name. If the different name cannot be selected, project is not saved. The rest of all project need to be selected as different name, not erusb.erp. 1). Select desired Memory type to EeRom-8U connected to "EEROM Control" page. 2). Add file that you will work on to project. 3). Selecting that which file you download to which connected EeRom-8U device at "EEROM Select" menu of menu. 5). Selecting that starting Buffer address of downloaded file and file offset from "Address Information" menu. 6). "Selecting that Reset option that is applied when performing Target Run at "Option" page. 7). Starting downloading. *8). If project name is still erusb.erp, whether you want to save project as different name is asked when exiting program. If you click Cancel button, project is not saved; therefore, saving as different name is recommended. "Project Control" page. 4). "Selecting that whether you split the selected file at the left side of "Data Split" 2. Data Split Mode This program basically performs with 8bit(Byte) mode and supports splitting data of 16bit(Even, Odd) and 32bit(Word0, Word1, Word2, Word3). After loading file, this program performs within Buffer, and there is no effect to original file. 1). If downloading file with splitting to 16bit, 2 EeRom-8U instruments, and if it is 32bit, 4 instruments are required to be connected. 2). Selecting EeRom-8U instrument from Split Mode www.eetools.com - 24 - EeRom-8U User's Guide After connecting EeRom-8U instrument and reading Serial Number by program, EeRom-8U Software arranges Serial Number in order. In other words, EeRom-8U that has the lowest Serial Number becomes number 0. Afterwards, whenever you select Split mode, assigning Serial Number is started from the EeRom-8U that is selected from "EEROM Start" by program. - 8bit : Byte. - 16bit : Even, Odd. - 32bit : Word0, Word1, Word2, Word3. - 25 - www.eetools.com EeRom-8U User's Guide Chapter 4 TROUBLESHOOTING & TECHNICAL SUPPORT www.eetools.com - 26 - EeRom-8U User's Guide I. TROUBLESHOOTING Regardless of the symptom, verify the following: 1. 2. 3. There are no "dongles", security keys, switch boxes or other devices between the EeRom-8U download cable and the USB port. The target is powered up. All download, daisy-chain and target interface cables are tight and fully inserted. Verifies, but target does not run Target not being reset If the wrong reset output is being used or it is connected to the wrong spot on the target, it may not be resetting the target during the download. We would get a good download, but the target was fetching garbage during the transfer. Some processors In either will HALT, others will simply execute the random garbage they received. event, the processor will not "know" to start over and execute the new code. Try removing the reset line, turning off the target power for 10 seconds and then turning the power back on. If the target now comes up and runs, the reset signal connection was wrong. While you could do this after each load, we highly recommend correcting the reset problem to make resets automatic and to prevent the target from running garbage during the download. Emulator device size set wrong. The device SIZE configuration affects only the TARGET'S view of the emulator. The file will download and verify correctly as long as the emulator is large enough to hold the file. If the size is set too small, the target will not be able to access the entire file For example, if the file is 60,000 bytes long, it would load into an EeRom-8U However if the emulator is configured to emulate a 27256, the image. and verify properly. space. target would see only the first 32Kbytes mirrored into both halves of the 64KByte This is exactly what would happen if you burned the first 32Kbytes into a 27256 and plugged it into the same socket. - 27 - www.eetools.com EeRom-8U User's Guide Wrong PLCC or other adapters used. Any adapter used between the target cable and the target socket itself has the potential of introducing errors. model and manufacturer. In particular, PLCC footprints vary by EPROM size, Most FLASH chips are pinned out like In general, In general, small EPROMs (<1Mbit) generally have one pin out and larger EPROMs have a different pin out. large EPROMs. However, SOME small FLASH are wired like SMALL EPROMs. large devices (>=1Mbit) use a 32 pin DIP to 32 pin PLCC adapter. Smaller devices usually need a 28 pin DIP to 32 pin PLCC adapter but MIGHT need the 32 pin version. Give us a call if you are not sure. Common problems and solutions 1). Software doesn't recognize EeRom-8U device - Check that red Power LED of EeRom-8U is on. - Check that USB Cable is connected correctly. - Click "Setting" -> "Hardware Profile" -> "Device Manager"-> "Universal Bus Controller" and check that the corresponding driver is loaded correctly. - If you have any further questions, please contact with our technical assistances. 2). After downloading and Target Run, Target doesn't seem to be performing correctly. - Check that green light of Status LED is on when downloading. - Check that the selected Target power and EeRom-8U power are correct. - Check that the Cable and the socket are connected properly to Target. - If you have any further questions, please contact with our technical assistances. 3). Software is down and stops performing. - Unplug USB Cable and shut down Software. - After a while, connect the Cable again and start Software. - If matter seems not to be better, please contact with our technical assistances. 4). Reset doesn't start. - Check that Reset Cable is connected properly to Reset pin that is placed in the side of EeRom-8U. - Check that Reset Cable is connected to the right Reset terminal of Target. - Check that the selected Reset Type is correct from Option of Software and the www.eetools.com - 28 - EeRom-8U User's Guide Reset Duration is selected correctly. (For example, `0' is selected as a default value for Reset Duration.) Reset Duration is the time period that Reset Signal is maintained.
