Part Number:MSP430AFE253
你好,我现在使用msp430afe253芯片开发,有用到flash存储数据,可以正常读写flash,但是设备频繁上下电测试时,会出现flash被清空的现象,请问这是哪里的问题,flash代码参考的是官方样例代码;
Yale Li:
我已经咨询了相关工程师:

Jason Chen:
程序上电期间没有进行flash写操作,上电间隔大概1-2秒

Yale Li:
Is this a new design or has this product been in the field for some time and they are now experiencing this issue?
This device has both INFO and MAIN memory sections. Do we know if the corruption occurs in one or both of the sections?
Are you enabling the SVS (Supply voltage supervisor) and what settings?

Jason Chen:
你好 这是新开发的一款产品,使用的DCO没有使用外部晶振电路,数据存储在信息区,没有使用SVS。

Yale Li:
好的,我跟进过去了
