CC2538: How to modify CC2538 ZNP code with Z-Tool Application using a USB-Serial Converter .

Other Parts Discussed in Thread: Z-STACK

I am in a similiar situation with the one in e2e.ti.com/.../795089

I set flowcontrol false, BR 115200 and MT_SYS_KEY_MANAGEMENT flag set in C/C++ Compiler -> Preprocessor tab .

My existing code is on CC2538ZNP-Debug,and i flash the D:/Texas Instruments/Z-Stack 3.0.1/Projects/zstack/ZNP/CC2538/CC2538ZNP-Debug/Exe/ZNP.out.

I use a USB-Serial Converter by connecting GND , EM_UART_TX & EM_UART_RX pins of SmartRF06.

And i removed the jumper on Enable UART over XDS100v3 pins.

 

But there is still the "no device found" response.

My set is like the attachments.Is there anythings wrong?

 Thanks.

    For UART init parameters, you should revise the one in npInit of znp_app.c. I just verify it again on my CC2538DK and it works correctly.

    I revised the code just like the attachement.But there is still 'no device found'.I am using  SmartRF06 Evaluation Board.

    Do I need to revise the flag set in C/C++ Compiler -> Preprocessor tab？ And how？ Thanks.

    My flag is like this.

    HAL_UART_USB
    USB_SETUP_MAX_NUMBER_OF_INTERFACES=5
    xHAL_SPI=TRUE
    HAL_UART=TRUE
    BDB_FINDING_BINDING_CAPABILITY_ENABLED=0
    TC_LINKKEY_JOIN
    ewarm
    CC2538_USE_ALTERNATE_INTERRUPT_MAP=1
    CC2538ZNP
    ZNP_ALT
    xPOWER_SAVING
    FEATURE_SYSTEM_STATS
    FEATURE_RESET_MACRO
    ZDNWKMGR_MIN_TRANSMISSIONS=0
    MT_UART_DEFAULT_OVERFLOW=FALSE
    ASSERT_RESET
    FAKE_CRC_SHDW
    ZCL_READ
    ZCL_DISCOVER
    ZCL_WRITE
    ZCL_BASIC

    I am doing my  graduation design. It is urgent.

    You have to disable HAL_UART_USB. The followings are my predefined symbols.

    xHAL_UART_USB
    MT_SYS_KEY_MANAGEMEN
    USB_SETUP_MAX_NUMBER_OF_INTERFACES=5
    xHAL_SPI=TRUE
    HAL_UART=TRUE
    ZNP_ALT
    BDB_FINDING_BINDING_CAPABILITY_ENABLED=0
    DISABLE_GREENPOWER_BASIC_PROXY
    TC_LINKKEY_JOIN
    ewarm
    CC2538_USE_ALTERNATE_INTERRUPT_MAP=1
    CC2538ZNP
    ZNP_ALT
    xPOWER_SAVING
    FEATURE_SYSTEM_STATS
    FEATURE_RESET_MACRO
    ZDNWKMGR_MIN_TRANSMISSIONS=0
    MT_UART_DEFAULT_OVERFLOW=FALSE
    ASSERT_RESET
    FAKE_CRC_SHDW
    ZCL_READ
    ZCL_DISCOVER
    ZCL_WRITE
