MSP430FR2422用作 RTC、3.0V 电池作为备用。
系统在正常运行(AM)期间运行@ 5V 电源。当无电源(5V)时、系统切换至3.0V 电池 电源和控制器开关
将唤醒源作为引脚中断和 RTC 计时器溢出 中断的 LPM3、5设置为 LPM3。
问题案例：当系统在工作模式下从5V 电压运行时，某个时间控制器挂起且从不恢复。 仅在上电复位时恢复。
注意：当控制器挂起时，它会观察到它始终处于活动模式，而不是处于 LPM。
Prashanth、您好！
您没有直接从5V 电源轨运行 MSP430FR2422、对吧？ 根据您的措辞、我认为不是这样、但我只想确保。 此外、您在多个电路板上还是仅在单个电路板上看到这种情况？

如果 缩短此间隔、您是否看到故障发生得更快？

您好！
MSP430FR2422 将从两个电源获取电源
1.外部5V，转换为3.1v。
2.无 外部电源时的板载电池3.1v。

在正常运行(AM)下、它溢出@34 min、即65279计数
在从 AM 转换到 LPM3.5期间。
RTC 将重新配置为在2秒(即64个计数)发生溢出。这样我们就可以验证
电源转换、并且由于噪声而未触发。 验证后、将 RTC 溢出配置回34分钟
断电 检测通过使用 ADC (使用 v ref internal 1.5v 配置)完成。

您好、Brandon、
以下是我的主 UART ISR 缺失( 那里没有这样的挂起代码，但假设标志是自动清除，我不清除那里的任何标志)。
多个电路板存在该问题、
测试条件：电路板使用连续5V 电源运行，RTC 电路板连接到另一个5V 电源的电路板
提供给我们的 RTC 板。电机和螺线管等负载连接到其他板、因此可能会产生噪声。
某些时间板在10分钟内挂起、甚至需要一天的时间。

Prashanth、您好！
您可以尝试通过在 MSP430FR2433中设置 JTAG 电子保险丝来禁用 JTAG。 更多详细信息、请参阅本文档的第2.2.3节(SLAA685)以及《MSP430FRrxx 和 MSP430FR2xx 系列用户指南》的第1.11.1节。 用户指南确实指定了 JTAG 和 SBW 接口保持正常工作、 只是 某些命令访问受到限制、因此您可能仍会看到挂起、但值得一试。
请记住、此过程只能通过在器件上使用 BSL 模式来实现反向。 如果您目前没有执行 BSL 批量擦除的直接设置、我只会在您的其中一个电路板上尝试它。
此致、
Brandon Fisher
