Hi,

Is there an emulator available for the Stellaris??

Thanks in advance

You don't need an emulator for Stellaris!

In fact, you really don't even want an emulator - they are big, nasty, cumbersome, expensive things: http://bit.ly/QOtEH5

All you need is a Debug Adaptor to give you access to the internal debug hardware within the Stellaris chip: http://bit.ly/SUv1mg

These are also commonly known as "JTAG Adaptors", or "JTAG Probes", or similar - as JTAG is (or, until recently, was?) the commonest form of connection to on-chip debug hardware.

http://en.wikipedia.org/wiki/Joint_Test_Action_Group

You will need to choose an adaptor which is compatible with whatever software toolset you are using.

eg,

Keil have uLink: http://www.keil.com/ulink/
IAR have various options: http://www.iar.com/en/Products/Hardware-Debug-probes/
Code Red Technologies have RedProbe: http://www.code-red-tech.com/red-probe.php
etc,...

TI's own Stellaris boards have the debug adaptor built-in (most manufacturers are doing this these days).

Summary: you don't need an emulator, you just need a debug probe - which is integrated on TI boards.

I dont want to use the hardware to be connected, to debug the program.

Can i emulate the hardware?

You mean you want a Simulator - not an Emulator ?

(the distinction is explained in the post awaiting moderation)

But, yes - various toolchains do offer various degrees of Simulation...

Ya sorry, I meant a simulator.. not an emulator..

So your question is answered?

0 Karthi Prime over 13 years ago in reply to Andy Neil

Nope. Still question is:

Currently i load the program into the controller board, use In circuit emulator(on board) to debug the program.

I want to debug the program and see the various port/register values without connecting the actual controller, i.e., by simulating them. for which any simulator available?

Thanks

There is no simulator that I know of that is going to let you do any meaningful debug of an actual application. There is a Cortex-M simulator as a target within CCS, but that is just simulating the core. It is useful for testing algorithms and things that do not need to do any IO. You can use it to measure processor cycles and do code coverage and things like that, but it does not simulate any peripherals or IO. At one time, Keil had within their uVision IDE a fairly complete Stellaris simulation but I dont know if that is still maintained.

ya let me check on the keil..

Thanks

Which does answer your question, "Is there an [simulator] available for the Stellaris??" - doesn't it?

They have given up trying to maintain complete simulations of all the peripherals for all the chips they support.

Hi,

May I ask how to do Code Coverage using TI Cortex M3 Simulator in CCS?

Regards,
Wilson

You may - but hijacking an unrelated thread is not the best way to do it!

Start a new thread with your specific question.
