SysCtl_disableSRAMBank(SYSCTL_SRAM_BANK2); 变量SYSCTL_SRAM_BANK2 CCS不认识

我在TI例程内加入了您的上述语句是可以的

程序如下

 * MSP432 Clock System - Clock Source Initialization
 *
 * Description: In this code example, the CS_initClockSignal is used to
 * initialize every clock on the controller to a non-default value. The
 * CS_initClockSignal function is one of the most convenient CS functions as it
 * provides a readable/usable method for users to initialize specific clock
 * sources to a specific clock signal. Once each clock source is initialized,
 * the convenience functions that get clock frequencies are used to assign
 * the frequencies to variables. The user can pause the debugger to observe
 * that the correct frequencies have been assigned to the variables.
 *
 * MCLK = MODOSC/4 = 6MHz
 * ACLK = REFO/2 = 16kHz
 * HSMCLK = DCO/2 = 1.5Mhz
 * SMCLK = DCO/4 = 750kHz
 * BCLK  = REFO = 32kHz
 *
 *              MSP432P401

您现在有没有将driverlib的路径加入工程？如下图所示
