i2c in two cores

[guhof1822]

Hello everyone,

I am using two tasks, one in each core of esp32 wroom . Both tasks using the same i2c channel, EEPROM and ds3231. But when i write a single float number in eeprom, with the other task in 'delay', the DATE of ds3231 is changed. I have sure that I write in EEPROM when the other core are in 'delay', the is no conflict in i2c channel. Why the DATE of ds3231 is changed ??

How could anyone possibly answer that without you posting code ?
