此时,如果在Flash之前手按Boot再按Reset,Flash成功的概率至少高1倍,否则,Flash 5次至少失败4次,按住Boot 5次可能只失败2~次。 另外,就是Flash完了之后,无法启动,monitor输出如下: Build:Oct 25 2019 rst:0x1 (POWERON),boot:0x18 (SPI_FAST_FLASH_BOOT) SPIWP:0xe
ESP32 断电数据保存 EEPROM数据读取和写入 EEPROM (electrically erasable programmable read-only memory)是一种用户可修改的ROM,又或者称为闪存(Flash Memory)。它可以通过施加高于正常电压的电压,就可以反复擦除和重新编程(写入)的闪存 。 EEPROM 是一种非易失性ROM,可以擦除和重新编程单个字节的数据。这就是 EEP...
