LP-EM-CC2745R10-Q1: Restore eval board to original firmware

Part Number: LP-EM-CC2745R10-Q1
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

We are just getting started with this eval board.  Out of the box, the board was advertising and working with the Android app (SimpleLink Connect).  We complied an example (ble/data_stream/freertos/ticlang) with a make tool and the TI compiler without problems.  Using Uniflash and XDS110 we connected to the target and were able to install code,  The banner at the top of the Display gave "Data Stream", but did not provide a  BLE advertsement .  We uploaded the file "prebuilt_hexfiles/data_stream_app.hex" and it produced the same result (no BLE advertisement). 

In configuring the UnitFlash App, we may have erased or otherwise misconfigured something important, the CCFG, for example,  may have been erased.

How can we get the target device back to it's original factory state?

Cheers 

Mike

    Issue is resolved.  As it turns out, the HSM FW was erased.  

    From the README.md in simplelink_lowpower_f3_sdk_9_12_00_19/bin/hsm

    ## Can the HSM FW be erased?

    Although the HSM FW is write/erase protected from the application. It is still
    possible to erase the HSM FW via back-to-back Chip Erases. This is unlikely, but
    possible to be done accidentally due to various programming errors. If this
    should happen, the HSM FW need only be provisioned once again. 

    At the bottom of the UniFlas/Settings&Utiliites this is a button to Program HSMImage  but the path to simplelink_lowpower_f3_sdk_9_12_00_19/examples/rtos/LP_EM_CC2745R10_Q1/hsm/hsmfwupdate/cc27xxx10_hsm_fw_v3.0.0.bin must be provided.  

    In our ignorance, we must have done a back to back Chip erasure or some other sillyness.
