Is it possible to reset the eeprom?

I ran the calibration once (I made sure to run the correct version: teensy_inv using teensy 3.6 and mpu9250/bmp280 version sentral), but when attempting to rerun, it looks like the eeprom has been corrupted:

No I2C devices found

Sentral Status: 255 (Should be 11)

I connected to a linux device and when set in passthrough mode, I'm no longer seeing the eeprom data or id register on the bus (using i2cdetect).

Thanks!

It looks like something is wrong with the I2C bus; no devices are being detected. Even if the EEPROM is corrupt, I think the EM7180 should still ACK at address 0x28...
