两个模块是独立的，自然可以各做各的事情。 硬件I2C去读24c芯片，当然可以，库里都有现存的API函数可以调用。 查询方式、中断方式、DMA方式的都有。 Repository\STM32Cube_FW_F4_V1.28.1\Projects\STM32F4-Discovery\Examples\I2C
每次擦除都是同一个区域，基本上是固定逻辑引起的，通常和软件关系比较大。 芯片通常有写保护功能，检查一下，将对应的区域写保护，这样就能通过打补丁的方式解决。 否则需要找出问题所在，通常这种逻辑都比较隐蔽，（当然一些偏移量的计算，栈溢出可以容易验证）。毕竟开发时都是按正常逻辑设计的。 上电和掉电复位的确会引起一些故障，也正如你所说，是随机的故障概率比较大。
从上面分析看门狗是正常的，可能是程序没有执行，可以在喂狗的操作中，或者开个定时器，定时输出波形。另外可以增加串口通讯，测试收发数据。如果还不好确定，看一下与显示屏的通讯是否还有波形再输出。
