Other Parts Discussed in Thread: CC2640

LCD works well for factory default binary (PER test).

But when I download cc2640 ble binary(eg. simpleBLEPeripheral, SimpleBLECentral), LCD didn't work.

Is there anyone who can tell me why...

    When you download BLE hex file for CC2640, there are two hex files, CC2640Stack and CC2640App and you have to download both.

    How do you download the images? If you are using Smart RF Flash Programmer make sure to only erase "pages in image" and not the entire device.

    oh, no

    I select ALL(MASS erase) to download images.

    Is there any way to recover it?

    What's the difference between "pages in image" and "(MASS erase)"?

    And I only find SmartRF Flash Programmer 1 User Manual on Ti website.

    Is there any document about "SmartRF Flash Programmer 2"?

    After you install Flash programmer 2 and run it, you will see a question mark "?" on top-right corner. You can press on the question mark and will see manual.

    Hi,

    There is no need to recover anything, simply upload the images again.

    The two images (Application and Stack) are fully separate so when uploading the program you have to do it in two steps. You should only erase the used pages for the image before uploading a new one and not the full flash. Doing so would leave you with only one of the two images in the device after flashing.

    Smart RF Flash Programmer 2 (for CC26XX and other JTAG-based CC devices) documentation is included within the tool itself and not in a separate document.
