求助 合宙ESP32C3 EEPROM操作失败

youranda

想要使用板载的4M EEPROM，写了一个最简单的统计启动次数的程序，结果输出一直是0
即使使用EEPROM.begin()和EEPROM.end()，也是为0

1. #include<EEPROM.h>
   
2. 
   
3. void setup()
   
4. {
   
5.   unsigned char start_time = 0;
   
6.   
   
7.   //串口初始化
   
8.   Serial.begin(115200);
   
9.   start_time = EEPROM.read(0);
   
10.   Serial.printf("start time = 0x%x\r\n", start_time);
    
11.   EEPROM.write(0, start_time+1);
    
12. }
    
13. 
    
14. void loop()
    
15. {
    
16.   delay(1000);
    
17. }

EEPROM用之前要begin, 写入后要commit

EEPROM用之前要begin, 写入后要commit

加上begin和commit还是不行，加上end也尝试了，好纠结

1. #include<EEPROM.h>
   
2. 
   
3. void setup()
   
4. {
   
5.   unsigned char start_time = 0;
   
6.   EEPROM.begin(10);
   
7.   //串口初始化
   
8.   Serial.begin(115200);
   
9.   start_time = EEPROM.read(0);
   
10.   Serial.printf("start time = 0x%x\r\n", start_time);
    
11.   EEPROM.write(0, 0x88);
    
12.   EEPROM.commit();
    
13.   EEPROM.end();
    
14. }
    
15. 
    
16. void loop()
    
17. {
    
18.   delay(1000);
    
19. }

运行了官方例程都不行呀，感觉板子有问题~

更新到 2.0.4  就正常了，以前的2.0.3 不能存储。已经试验存储已经OK了！
