Zilog Developer Studio II – Z8 Encore!

User Manual

– Verify File Downloads – Upon Completion checkbox

This command does not download the software. Use this command to access target regis-

ters, memory, and so on without loading new code or to avoid overwriting the target’s

code with the same code. This command is not enabled when the target is the simulator.

This command is available only when not in

Debug mode.

For the Serial Smart Cable, ZDS II performs an on-chip debugger reset and resets the CPU

at the vector reset location.

Download Code

The Download Code command downloads the executable file for the currently open proj-

ect to the target for debugging. The command also initializes the communication to the tar-

get hardware if it has not been done yet. Starting in version 4.10.0, the

Download Code

command can also program Flash memory. A page erase is done instead of a mass erase

for both internal and external Flash memory. Use this command anytime during a debug

session. This command is not enabled when the debug tool is the simulator.

The current code on the target is overwritten.

If ZDS II is not in

Debug mode when the Download Code command is selected, the fol-

lowing process is executed:

1. Initializes the communication to the target hardware.

2. Resets the device with a hardware reset by driving pin #2 of the debug header low.

3. Configures the device using the settings in the

Configure Target dialog box.

4. Downloads the program.

5. Issues a software reset through the debug header serial interface.

6. Configures and executes the debugger options selected in the

Debugger tab of the

Options dialog box. If it is a C project, ZDS II resets to the main function if it is

found. 

If ZDS II is already in

Debug mode when the Download Code command is selected, the

following process is executed:

1. Resets the device using a software reset.

2. Downloads the program.
