CC3220SF-LAUNCHXL: Error serial port

Hi,

You need to use Uniflash software and switch device into development mode - please see this SimpleLink academy article.

Be aware that CC3220SF devices are not fully supported by Energia.

Thanks Jan,

What do you mean by development mode? I have read this terminology als very often. So I get the following using UniFlash by image creator, so how to proceed and where is development mode?

I see it. At one point he is asking Select "Import Project from ZIP file." Where are these Project from zip files?

Hi,

Import and export of Uniflash project is intended when you want tom move Uniflash project to different computer.

I am lost Jan. I have done all the steps up to there. So what is the next step? Is it now ready to be used in CCS?

Hi,

When image in development mode is uploaded by the Uniflash software than JTAG is unlocked and you can debug from CCS via JTAG or SWD. I think SImpleLink academy article is pretty clear in this meaner. Additional information about Unilfash you find at this document. Information about OOB example you find here.

Thank you Jan.

It is working. Program runs.

What is the reason behind this? As I ask in my original post MSP432 does not need UniFlash. So what is the reason and motivation from TI behind this such that one first has to unlock JTAG in UniFlash?

Is it marketing?

Hi,

No. This is a security feature. CC3220/CC3235/CC3230 devices are devices with many security features including safe boot. Enabled JTAG/SWD is a security risk. From this reason developer need to set development mode intentionally.

Last question:

How often do I have to do this, I mean configuring it in development mode? One time?

I would like to thank you for clearing everything.

Cheers,

Mostafa

Hi,

Development mode is part of SPI flash image (sFlash), that means you should set development mode together with programming image using Uniflash every time you do this.

Dear Jan,

You mentioned that CC3220SF devices are not fully supported by Energia. In the following link 

https://www.digikey.com/en/maker/projects/control-a-cc3200-launchpad-with-your-phone-using-blynk/85c726146f3749058bc9b13d6a0698ba

There Daniel uses Blynk, Energia and CC3200 for IoT. Very nice project. Is it possible to realise that project with CC3220SF?

I promise this was the last question. 

Hi,

Sorry I am not able able answer your question because I don't tested that Energia code.

But I think that you can expect a issue in execution of Energia code at CC3220SF device at XIP (internal) flash. Additional information (and two solutions) you can find here.
