- Wed Nov 26, 2014 6:03 pm #3349 I would like to be able to debug and simulate firmware with the IDE that comes with the VM.

I have installed the "NO-VM" and fixed the license. I can open Xtensa Xplorer without problems, however, I have not managed to set up a project properly nor debug or simulate a thing. Of course I have read thoughtfully all the related posts. I believe that some people like tinhead viewtopic.php?f=9&t=142&p=747&hilit=xtensa+xplorer#p747 , maybe mamalala, and some others have used Xtensa Xplorer successfully.

I (and surely others too), would greatly appreciate if you could briefly explain how to do it (i.e put SDK files & folders here, put this other files in a folder for your project, follow this steps to create a new project in Xplorer and follow this other steps to debug your code).


Thanks a lot in advance

Cadence provides a simulator for the processor core, but unless Espressif has provided a simulator model for the whole chip (which is presumably not an easy thing -- is there any evidence of it? I haven't searched), you won't be able to simulate anything to do with I/O, flash, WiFi, etc.

It would be many times more expensive if they had to polish their product in a trial-error fashion. A different story is whether if they will release them to the general public, under NDA or not at all. (Hopefully they'll make it available for everyone!)

Nevertheless I am not aiming that high. I would like to know at least how to setup the project properly in Xtensa Xplorer, run the program step by step, maybe check the variables and be warned about coding mistakes.

Someone who has done this under Xtensa Xplorer or another IDE, could you please tell us the steps needed?

Regards
