Your emulator stays in reset mode
Your emulator is connected to your application board. When you try to run your
program, you observe that the LED ST9 Reset remains switched on. When you
stop your program, the program counter is pointing to the reset vector.

Verify that your application board is powered up. When your emulator is
connected to your application board, it can detect whether your application
board is powered up or not. If not, the emulator will remains in reset state.
Verify that the reset line on your application board is not pulled low. When your
application board is reset, the ST9+ chip will remain in reset also, when you try
to run your program.
You should not display contents of memories such as FIFO, LIFO... Otherwise
you could lose the synchronisation of your memory when the display reads its
contents.
The same problems can also occur when the memory area you selected to
display in the Memory window overlaps such memories.
For example, your FIFO is located at address 0x01C000, some RAM is located
at address 0x018000 to 0x01BFFF, and you display the memory space from
0x01BE00. Depending on the size of your Memory window, the display can
show memory contents up to 0x01C0ff and cause problems in your FIFO.
In that case, it is advised to take special care with the size of the Memory
window.
If you are asking for a display of external memory mapped as user memory,
you have to configure the external memory interface using EMR1, EMR2, and
P0Cx, P1Cx, P2Cx registers as your final software should do before asking for
the dump.
When using the Memory window, the ST9+ wait states are configured
differently than when you are running your program. Two wait states on Data
be IEEE-1284 compliant: check that proper mode (Centronics Compatible
Mode) is installed in your PC’s BIOS.
If a dongle (hardware key required by some PC software) is already
connected to the PC parallel port, it should not interfere with the emulator.
However, if you notice a malfunction, you should remove the dongle(s) and
try to establish the connection again.
