CC2652R7: "FrontEnd not found" for certain 2.4GHz front-end options?

Hi All,

I'm working on a development using the CC2652R7 and our HW team needs several different test builds to do RF testing. In the past, we have used a slightly modified version of the rfCarrierWave sample project to do this testing. But, this product uses a different antenna design and I can't reuse those binaries.

I went back to the old project and initially was unable to change the type in SysConfig to what I need, Internal Bias, Single-Ended mode RFP. The issue here appears to be that the version of SysConfig we were using did not expose this option. So, I updated it. I also updated the SimpleLink SDK to make sure it would support the newly available options. However, I get the following build error:

**** Build Finished ****

To rule out issue with upgrading the existing project, I started fresh with a new sample from the latest version of the SDK. The only changes I made were to set a custom board (required to change the front-end) and the front-end setting and I get the same error.

Any suggestions as to what I'm doing wrong? Thanks!

Hi Steve,

Thank you for alerting us of this erratic behavior. It appears that proprietary RF examples do not share the same frontend_settings.json as the BLE or IEEE 802.15.4 project counterparts. You can add IS_RFP settings to <SDK directory>\source\ti\devices\radioconfig\.meta\config\cc2652r7_prop_pg10\cmd_settings to resolve this error:

                            ]
                        }
                    }
                ]
            }
        ]
    }
}

As the CC2652RX devices do not have a Sub-1 GHz radio, some of the options within these files appear to be incompatible with this device. I will submit a ticket to the SysConfig Team to address this issue.

Regards,
Ryan

That did it. Thanks Ryan! I couldn't figure out where the IS_RFP setting was translated to the config flags, but now I know. I've added a link to this post to my release notes in case someone else inherits my project down the line.
