SIMPLELINK-LOWPOWER-F3-SDK: UART Demo doesnot work in SDK for LP-EM-CC2745R10-Q1

Part Number: SIMPLELINK-LOWPOWER-F3-SDK
Other Parts Discussed in Thread: LP-EM-CC2745R10-Q1, AWR2944EVM, AWR2944PEVM, TMP117, BP-BASSENSORSMKII

Hi

The multi-threaded application can compiled without error in 

C:\ti\simplelink_lowpower_f3_sdk_9_14_01_16\examples\rtos\LP_EM_CC2745R10_Q1\demos\portable

However, this example program stucked after the first UART2_write.

UART2_write(uart2, consoleDisplay, sizeof(consoleDisplay) - 1, NULL);
 
I tried different ways to debug this line and without any success.
For example, i tried double run of this line and I can only get one output in serial port.
> Console (h for help)
In my test, two lines of the same output are expected.
 
Could some one have the same problem?

    Hi Kang,

    Are you using a BP-BASSENSORSMKII BoosterPack on top of the LP-EM-CC2745R10-Q1 (explained in the example README)?  Otherwise you will find in the debugger that you are stuck on the first I2C_transfer

    If you were to remove temperatureThread from being used in main_freertos.c through pthread_create then you would at least be able to further evaluate the consoleThread.

    Regards,
    Ryan

    I thought that this board has a temperature sensor:

    "The AWR2944EVM/AWR2944PEVM provides access to an on-board temperature sensor (TMP112AQDRLRQ1)"

    Does this sample code not use the on-board sensor?

    I have no knowledge concerning the AWR2944EVM as this is a different product group at TI.  I can only imagine that this environment would be very different from the LP_EM_CC2745R10_Q1 + BP-BASSENSORSMKII using the TMP117.
