During the load and/or verify, the STATUS LEDs of all involved emulators will flash RED as they are
accessed. At the completion of the transfer, target reset will be released. At this point, the STATUS LEDs
will indicate the target status (RED = no target power, GREEN = target power good, FLASHING GREEN
= target accessing the emulator).
The EconoROM III loader is very flexible, allowing any combination of emulators to be loaded in almost
any manner desired. The loader can load to individual units or automatically perform file splitting between
2 or more units. When the loader splits a file between multiple emulators, it will always place the FIRST
BYTE of the file into the LOWEST NUMBERED EMULATOR involved in the transfer. Successive
bytes are loaded into successive emulators. The following examples demonstrate this:
EXAMPLE 1
If you have two emulators daisy-chained together, and wish to split a file between them, you would specify:
“ER3LD filename /e2 /f1”. The /f1 is optional since the default is start with emulator #1. The /e2
parameter tells the loader that two emulators are involved in this transfer.
The loader will place the EVEN bytes (0,2,4..) of the file into emulator #1 (the LAST emulator in the
chain). The ODD bytes (1,3,5..) will be placed into emulator #2. Note that you control which emulator
holds the ODD bytes and which one holds the EVEN bytes by the order in which you daisy-chain the
emulators.
EXAMPLE 2
If you have four emulators daisy-chained together, a “/E4 ” parameter would cause the loader to perform a
32 bit split between all four emulators. Bytes 0,4,8.. would be placed in the lowest numbered emulator (#1
by default). Bytes 1,5,9.. would land in the next higher numbered emulator. Bytes 2,6,10.. would be end up
in the next emulator. Finally bytes 3,7,11… would be found in the highest numbered emulator involved in
the transfer Again the byte ordering is determined by the emulator daisy-chain order.
ER3TEST, ER3TEST32
These programs verify the reliability of the printer port and system wide communications with the
emulators. They also perform a very complete self-test of all attached emulators. These programs tests all
emulator functions except the actual target interface buffers and target interface cable/connection.
ER3TEST32 uses our ring-0 drivers to access the low-level printer port registers. It works under ALL 32
bit versions of Windows (including NT and 2000).
ER3TEST is a 16bit, DOS mode program. It operates under DOS and all versions of Windows EXCEPT
NT and 2000.
Utilities
The CDROM contains several command line utilities. The loaders provide all HEX conversions and file
manipulations needed so separate utilities are not really needed. They are provided to assist in manually
manipulating data files if desired. The utilities operate under DOS and ALL versions of Windows.
