Linux/CC3220S-LAUNCHXL: Cannot Program the Board

Tool/software: Linux

Hi,

I think this is the 3rd or 4th question I am asking here in recent days for which I did not get a reasonable answer; I hope someone can help me this time.

This is the steps I follow which leads to an unsuccessful "program image" process:

Build the netwrok_interface project for my board and generate a network_terminal_CC3220S_LAUNCHXL_tirtos_ccs.bin file (FYI I can debug this project inside the CCS successfully)
Open Uniflash
Select CC3120/CC3220 device
Start Image Creator
Create a new project (I'll call it test_project) with Develop mode as its Device Mode
Connect to the device
Go to User Files
Choose Select MCU Image
Choose the generated network_terminal_CC3220S_LAUNCHXL_tirtos_ccs.bin file
Uncheck the Secure checkbox
Click on Write
Don't touch anything else like the certificates or service pack or any other thing
Click on Generate Image
Click on Program Image (Create & Program)

This leads into Operation failed: fs_programming error: ret: -10372, ex_err: 2633 - FS_WRONG_CERTIFICATE_FILE_NAME error.

What am I doing wrong here?

Regards,

Aydin

I have tried this before. I tried it again per your request again but it failed once again with "almost" (the only difference is the "ret" value is now -10341 instead of -10372) the same error.

I checked out the prebuilt Out-of-the-Box project shipped with the SDK and saw that only one certificate (dummy-root-ca-cert) one is put in the image; I removed two other certificate files and used the dummy-root-ca-cert-key for encrypting the MCU image file and FINALLY programmed the board with success.

It is very strange that the guidelines in the http://www.ti.com/lit/ug/swru461/swru461.pdf document does not work for me; Maybe they are not written for a Linux machine!

Why there is no documentations or at least one "getting started guide" for Linux (and maybe Mac) machines while TI has created tools and SDK for all the platforms?

Hi Aydin,

You cannot uncheck the "Secure" checkbox for the MCU image in an CC3220S device!
You must sign the image and provide the full certificate (as explained in the getting started guide).
You can use the SDK dummy certificate for development or any valid one.
Make sure also to have service pack and root-certificate catalog installed.

Hi Kobi,

I tried the secure one as instructed in the getting started guide first but it did not work; After that I tried other approaches. As I said the instructions in the getting started document is not correct - at least for my set up - and I had to do it in another way.

Hi Aydin,

What exactly is different in your setup (aren't you using the Launchpad)?
What did you change (from the getting started instructions) to make this work?

I have stated that in my comments above. I just put one certificate in the image and used its key to encrypt the binary.

BTW, my major problem at the moment is https://e2e.ti.com/support/wireless_connectivity/simplelink_wifi_cc31xx_cc32xx/f/968/t/611550; I cannot do anything because of this.
