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!
Failed to use a /W parameter to split the file
If you want the loader to spilt the file between multiple emulators, you need to specify a /Wxx parameter.
Use /W16 for a 16 bit split, /W32 for a 32 bit split, etc.
Failed to use a /W16 parameter to load to a 16 bit emulator.
The loader treats a 16 bit emulators like two daisy-chained 8 bit emulators. If you fail to specify the /W16
parameter, the loader will load the entire file into the upper 8 bits ONLY. If the file is less than or equal to
? of the emulator’s capacity, it will even pass verify! In fact this is exactly how you use a 16 bit
Econo ROM II to emulate a single 8 bit device (with an external adapter).
File loaded into the wrong emulator(s)
If you have 2 or more emulators daisy-chained, you may have loaded the file into the wrong unit(s). Watch
the “SELECTED” LEDs to see which units where actually selected for the transfer. If you are skipping
emulators in the chain, remember that you must skip 16 bits for each 16 bit emulator and 8 bits for each 8
bit emulator.
Incorrect Byte Order
If you are loading into a 16 bit emulator, remember that the EVEN bytes will load into data bits D0-D7 and
the ODD bytes will end up in data bits D8-D15. If your target is wired reverse to this, you will need to run
SWAP.EXE on the data file before loading it.
If you are loading into multiple emulators with automatic splitting, remember that the loader will load the
FIRST byte in the file into the last emulator involved in the transfer. If the emulators are plugged into the
wrong target sockets, you can move them to the correct sockets or you can change the order in which the
emulators are daisy-chained.
Target Power noisy or Voltage too low.
Noise problems are very dynamic. It is possible that we could load and verify OK, but as soon as we release
reset and let the target start running, system noise increases and trashes the system. Low system voltage
could behave in a similar manner. It is possible that we could load and verify with a target voltage that is
well under spec, but the target will not execute properly. Econo ROM II draws more current than the
