Trouble Shooting
Avoid long distances between your Host-PC and the target. If you are using
standard parallel extension cable, the JTAG-BOOSTER may not work. Don't use
Dongles between the parallel port and the JTAG-BOOSTER.
Switch off all special modes of your printer port (EPP, ECP, ...) in the BIOS
setup. Only standard parallel port (SPP) mode is allowed.
On very fast PCs there could be verify errors. To avoid this, watch for the
´IO recovery time´-switch in the BIOS Setup which must be turned on. Otherwise
try to slow down your PC by setting the turbo switch off.
If there are problems with autodetection of the flash devices use the /DEVICE=
option. To speed up autodetection specify one of the options /8BIT or /16BIT.
Don't use hardware protected flash memories.
The used chip selects must be defined as output and inactive in the initialization
file (see chapter 1.8 “Initialization file JTAG386.INI”). Also the address bits must
be defined as output.
Use the option /NOWRSETUP to speed up flash programming.
