I. 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(15ns) 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 >
① High speed USB interface (Supports Plug & Play)
② 1M Byte (8M bit) / sec download speed
③ Supports 8bit data bus by itself
④ Uses 1MB high speed memory for proper emulation
: 15ns high speed SRAM
⑤ Supports EeRom-8U without outside electric power supply
⑥ Convenient software environment: supports Windows/9598/ME/2000/XP
⑦ Supports hex (Intel/Motorola type), binary file format
⑧ Disassembling function supports 11 CPU types
⑨ Safety circuit against inverse insertion

QUICK-START
TUTORIAL
EeRom-8U User’s Guide
- 25 - www.eetools.com
I. KEY PERFORMING EXAMPLE
1. Program performs for the first time.
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 “Project Control” page.
4). “Selecting that whether you split the selected file at the left side of “Data Split” 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.
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
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.

TROUBLESHOOTING
& TECHNICAL SUPPORT
EeRom-8U User’s Guide
- 27 - www.eetools.com
Regardless of the symptom, verify the following:
1. There are no “dongles”, security keys, switch boxes or other devices between the EeRom-8U
download cable and the USB port.
2. The target is powered up.
3. All download, daisy-chain and target interface cables are tight and fully inserted.
Target is not powered up.
EeRom-8U
draws its operating power from the target’s EPROM socket. The target must be
powered up during all load or verify operations. If multiple emulators are daisy-chained, they
must ALL be powered up to load to ANY of them.
Target power is noisy or Voltage too low.
EeRom-8U
draws more current than the EPROM it is replacing. If the target is a very low power
system, or is already pushing its power supply limits, it may not have enough current to spare to
power the emulator, causing power fluctuations or noise. This is a rare condition, but worth
mentioning
Checksum Errors
Checksum errors indicate a communications problem. This may be due to bad download cable
connections, a slow rise-time printer port, noise on the download cable, noise on the target
power, etc. You may try a slower download speed (increase the /d parameter). Also verify
that the download cable is not laying across a power transformer, your monitor, an arc-welder,
etc.
Target Power noisy or Voltage too low.
Noise problems are very dynamic. It is possible that we could identify the emulators but be
unable load and verify properly.

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 will HALT, others will simply
execute the random garbage they received. In either 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 all of the file image. For example, if the
file is 60,000 bytes long, it would load into an EeRom-8U and verify properly. However if the
emulator is configured to emulate a 27256, the target would see only the first 32Kbytes
mirrored into both halves of the 64KByte space. This is exactly what would happen if you
burned the first 32Kbytes into a 27256 and plugged it into the same socket.
File Too Large
If the file size exceeds the configured device size, the target will not be able to access the entire
file. Note that the file may still verify correctly, as long as it does not exceed the emulator’s
maximum capacity. If the emulator is configured correctly and the file is larger than the device
setting, your code has just outgrown its space. If you are emulating the maximum size device
the target is wired to accept, you will have to reduce the code size. If the target has some
unused space contiguous to the current EPROM space, you may be able to modify the target
board to accept a larger EPROM. This would typically involve adding another address line to
the socket and possibly modifying the EPROM chip select decodes. Of course you would need
to re-configure the emulator for the larger device as well (if it has room to spare).
Wrong PLCC or other adapters used.
Any adapter used between the target cable and the target socket itself has the potential of
introducing errors. In particular, PLCC footprints vary by EPROM size, model and manufacturer.

In general, small EPROMs (<1Mbit) generally have one pin out and larger EPROMs have a
different pin out. Most FLASH chips are pinned out like large EPROMs. However, SOME small
FLASH are wired like SMALL EPROMs. In general, 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.
File is not a raw binary image of the EPROM
The command line loader loads only unformatted, raw binary images. If the file is a formatted
HEX file, use HEX2BIN.EXE to convert it first. If you are not sure about the file’s format, “TYPE” it
to the screen. If you see random printable, non-printable and graphics characters, it is BINARY.
If you see well formatted HEX characters, it is a HEX file. Intel HEX files start each line with a “:”.
Motorola ‘S’ files start each line with an “S”. Tektronix HEX files start with a “%” or a “/”.
HEX2BIN automatically recognizes and converts 8 variations of these HEX formats.
Remember, your Resume’ will load and verify, but most likely will not execute properly!
