    Upgrading to WICED Studio 6.1

    LJYe_2922526

      Hi forum WICED wizards,

       

      I'm planning to upgrade to WICED studio 6.1 from 6.0.1 for CYW20706. Going through the release notes I noticed under section 5.4, there is a "New CYW20706A2 FW version CYW20706A2_001.002.011.0215".

       

      Will all the fixes provided by the new firmware apply when I compile my project under 6.1? In other words, do existing 20706s in the field need a ROM update?

       

      Thanks.

          Yes, when you compile your project with WICED 6.1, the new CYW20706A2 Firmware will be utilized. The latest firmware has the fixed mentioned in the releases notes.

          You can consider the FW as the library that is utilized when you compile your code. This is downloaded along with your application through WICED. If you want the devices in the fields to have the fix, then yes, you will have to perform an OTA with the new hex.

           

          I assume you are referring to the external FLASH when you say ROM.

            In our design the 20706 is not connected to an external flash, and the host downloads the .hcd firmware on every power cycle.

             

            I just want to make sure compiling and generating a new .hcd under 6.1 is all that's required. I'm hoping the ROM that's flashed when the chip is manufactured does not have to be reflashed ever, and is only patched by the .hcd when it's loaded to the chip's RAM.

              Perfect. The new hcd that's generated under WICED 6.1 is all that is required. The ROM is patched by the hcd when its loaded into RAM.
