    Hello,

    Yes, this feature is not supported on the CC27xx right now. I'm getting some more information about when it will be supported. I'll let you know tomorrow.

    Hello,

    It appears that it's not in the plan to support chip-erase through Uniflash as of now. However, you can still do chip-erase through CCS.

    Hi, 
    I looked in "On-chip flash" tool both in CCS 12.8.1 and CCS 20.1.0 but could not find Chip Ease when a CC2745R10 LP is connected?

    Hi Brian,

    Here is how to do a chip-erase on the CC2745 using CCS:

    1. Click on View --> Target Configurations:

    2. A window should have popped up called Target Configurations. Expand Projects --> <Project Name> --> targetConfigs --> CC2745R10.ccxml then right click on the .ccxml file and click Launch Selected Configuration: (I'm doing this on a CC2340R5 but the process is identical)

    3. A debug window will have popped up. Do not connect. Right click on Texas Instruments XDS110 USB Debug Probe... and click Show All Cores:

    4. Expand Non-Debuggable Devices and click and highlight, but do not connect, Texas Instruments XDS110 USB Debug Probe/CS_DAP_0:

    5. Go to Scripts --> CC23xx --> Chip Erase. Regardless if it's CC23xx or CC27xx, it'll still be under CC23xx:

    That should chip-erase the chip!

    Please let me know if you run into any issues.

    Best,
