CC2640R2F: Btool on CC2640 wcsp BLE stack.

Part Number: CC2640R2F

Hi

We are trying to run BTOOL (C:\ti\simplelink_cc2640r2_sdk_5_30_00_03\tools\blestack\btool)

on BLE stack((simplelink_cc2640r2_sdk_5_30_00_03\examples\rtos\CC2640R2_LAUNCHXL\blestack\host_test) )

CC2640R2F launchpad but with CXE build flag (WCSP setting).

But it fail like this: Device reset timeout.

Do we have any inconnect setting?

    Hello Aichi,

    I am assuming the host_test project was successfully flashed into the device.

    What COM port are you using? Please double check it is the UART one.

    Let me know,

    David.

    Yes, i have select correct com port.

    i had re-plug usb to tried again then meet below, any idea?

    BTW, i am using this prebild image:

    C:\ti\simplelink_cc2640r2_sdk_5_30_00_03\examples\rtos\CC2640R2_LAUNCHXL\blestack\hexfiles

    And whole thing will be ok if use BLE5 image.

    Hello Aichi,

    Please make sure you are executing BTool from the correct ble stack (same as the hexfile source). To do this, go to <SDK>\tools\blestack\btool and execute Run_BTool.bat

    Considering that you are using <SDK>\examples\rtos\CC2640R2_LAUNCHXL\blestack\hexfiles\cc2640r2lp_host_test.hex

    Let me know how it goes.

    David.

    Few more things we may need to clarify, if we use BTOOL on custom board,

    1. That host_test project and hexfile just needs UART communication to establish communication? Does it need any special of CC2640R2F pin to be controlled e.g. be pulled low/high?
    2. The UART communication for the host_test is Asynchronous or Synchronous (with RTS/CTS)? Is Rx and Tx connected to IOID_0 and IOID_1 if we choose CC2640R2DK_CXS?
    3. If we compile the host_test project we don’t longer need to have BLE stack Project or hex file to flash with the application code?
