LP-EM-CC2745R10-Q1: Chip Erase not possible in UNIFLASH

Part Number: LP-EM-CC2745R10-Q1
Other Parts Discussed in Thread: UNIFLASH, CC2340R5

Tool/software:

In this post LP-EM-CC2745R10-Q1: Issue with CC2745-Based MCU on TI LaunchPad it is mention how to do Chip Erase with UNIFLASH, but this feature is not available for CC2745R10?

  • 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,
