Subject: [Zephyr-devel] Problem in I2C interfacing with nrf52840


Hello everyone !!!


I'm trying to interface an EEPROM with nrf52840 using I2C protocol.


For this, I used  .../samples/drivers/i2c_fujitsu_fram example, I'm able to read bytes from memory, but I can't write anything in memory. It's write_bytes() function doesn't seem to be working.


Did someone faced the same issue? and what needs to be done to fix this?



Warm regards,
