CCS/MSP432-RTOS: ./syscfg/ti_ndk_config.obj error

Hello I am developing with msp432 and want to use tcpecho example program in timerled example program.

However, the following error occurs, and the cause is unknown.

unresolved symbol CfgAddEntry, first referenced in ./syscfg/ti_ndk_config.obj

CfgAddEntry, CfgFree, CfgNew, NC_NetStart, ,,,

How can I check the corresponding error?

    Hi,

    1. How can you know that using RTOS, the clock seems to operate at 32KHz.

    2. TCP / IP can't use without RTOS. The reason is that you can't find a TCP/IP example in NONE RTOS file.

    3. The ADC on MSP432E401 can reach to 2 MHz sample rate. I think it is possible. But I don't think you can finish transmit the data through TCP/IP in 10us. I think you can use UDP protocol to transmit the data, it will be faster. Anyway, you can first test the time using GPIOs of transmit data through Ethernet.

    Hi. Eason!

    Thank you for your kind reply.

    Does RTOS work at 32KHz? Is there any way to check Freq?

    It seems that it can be used up to 120MHz in the example of not using RTOS. Is RTOS possible?

    Thank you!!!

    Actually, As I know, the frequency is setting in Power_init() function. You can't know it. If you want to check, you need to look into the TI-Driver manually. As I know it is fixed to 120MHz.

    May be you can disable PowerMSP432E4_sleepPolicy and make a try. 

    To know the frequency, you can:

    1. read the register directly

    2. use a timer to see the clock frequency.
