MSP-EXP432P401R评估板突然无法下载程序

新买的一块开发板,今天刚用,刚开始可以下载程序,在我尝试将DCO放在48Mhz下运行时,突然无法下载程序。

报错信息:

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.

希望能够得到解答,感谢

应该是您在设置48M的时候有一些遗漏,请您试一下例程

dev.ti.com/…/node

//******************************************************************************
//MSP432P401 Demo – Device configuration for operation @ MCLK = DCO = 48MHz
//
//Description: Proper device configuration to enable operation at MCLK=48MHz
//including:
//1. Configure VCORE level to 1
//2. Configure flash wait-state to 1
//3. Configure DCO frequency to 48MHz
//4. Ensure MCLK is sourced by DCO
//
//After configuration is complete, MCLK is output to port pin P4.3.

Resource Explorer中的例程也无法下载,编译时没有任何问题。我在英文的论坛里发现一个人遇到和我一样的问题,他尝试了恢复出厂设置,但是没什么用。附上那个帖子的连接,e2e.ti.com/…/945961

Susan Yang:

我这边测试了一下是可以成功的,期待您的反馈。

您现在能否尝试使用uniflash来erase芯片?

 大概尝试了一下,程序仍然无法烧录,以下是报错信息:

请问您有恢复出厂设置的教程吗
