Frequently asked questions

How do I find my emulator software version?

You can find this information by using the 'help/about...' pulldown menu in the ez-ice or by viewing the readme.txt file.

How do I update the emulator firmware?

Run the ez-ice windows application, ensure all child windows are closed, and select 'options/update firmware'.

What is the workaround for IDMA boot mode issues?

Hold the target processor in reset while bringing up the emulator software, then write 'jump 0x0000' at PM memory location 0x0000 before initiating the boot sequence.

Why does single stepping ignore the /BR and /RESET signals?

Because of the operation of the emulator/processor interface, single stepping ignores the state of the target DSP's /BR and /RESET signals.
