CC3120: How to use UniFlash utility to create the gang image for CC3120?

Part Number: CC3120
Other Parts Discussed in Thread: UNIFLASH

Hi,

    Our device uses the CC3120 chip as the Wi-Fi network processor to perform the wireless operation. The CC3120 is controlled by the external MCU through the SPI interface. In addition to the firmware in the ROM, we also connect the CC3120 chip with the external flash.

    By checking document swra569, use can use the UniFlash utility to create the gang image and program it into the flash using offline programmer. I also studied the document swru469b, and tried to follow what chapter 4 says to create the gang image containing the Service Pack and the Device Configuration.

    Unfortunately, there is no "Create Image" button I could use to generate the gang image on UniFlash 3.4 and Uniflash 4.4.0. By the way, I couldn't select the "CC3120/CC3220" device in the supported list, only "CC31XX/CC32XX" instead. Even if I select the "CC31XX/CC32XX" device, I still can't find the "Create Image" button after adding the Service Pack and Device Configuration.

    What should be the correct UniFlash version used to generate the gang image for CC3120 chip offline(without connecting to device)? Or I need install other package to make it work?

    Thanks.

    Hi Todd,

    Uniflash 4.4.0 does support creating the gang image for the CC3120. To do so, go through Uniflash and launch ImageCreator as you would for a CC3220 launchpad. However, when creating a new project simply select the CC3120R like so:

    From there, you can add the servicepack from the SDK, then click on Burn -> Create Image -> Save BIN to get the gang image needed for SPI flash programming.

    Let me know if you need more clarification or help on this topic.

    Regards,

    Michael

    Hi Michael,

    Thanks for your information.

    I do find the Create Image button by clicking on the Burn button and save the bin file successfully.

    Thanks for your help.
