thank you very much。The program is executed in flash，we enable instruction cache,the problem goes away.

The above test code runs under the same clock configuration (480MHz). The _count and total_count in the test code are sometimes the same (_count ~=total_count ~=60000) and sometimes different (_count ~=13000, total_count ~=60000). When it is differen...

The program will read the RTC value many times a second, or read the RTC value only once in a few seconds, and then upload the RTC time and other information to the server in real time through the network, and the server will regularly compare the lo...
