【求助】MSP432被锁了

移植一个SPI的DDS驱动到MSP432P401R上成功后觉得SPI不够快
于是我想改一下DCO的（因为SPI是SMCLK的）
于是我在关闭WDT后调用了
CS_setDCOFrequency(48000000);
和CS_initClockSignal(CS_SMCLK, CS_DCOCLK_SELECT, CS_CLOCK_DIVIDER_1);

编译通过了但是调试的时候提示
CORTEX_M4_0: * WARNING *: The connected device is not MSP432P401R
CORTEX_M4_0: GEL Output: Memory Map Initialization Complete
CORTEX_M4_0: GEL Output: Halting Watchdog Timer
CORTEX_M4_0: Error initializing flash programming: Your XMS432P401R material is no longer supported. We recommend you moving to production-quality MSP432P401R/M silicon by ordering samples at www.ti.com/product/MSP432P401R.
CORTEX_M4_0: Loader: One or more sections of your program falls into a memory region that is not writable.  These regions will not actually be written to the target.  Check your linker configuration and/or memory map.


请问各位大佬如何解决啊。。。很急很急。
