We are in exactly the same situation as this user: Dynamic DTB/DTBO loading (and my impression is that a lot of other devs are in the same shoes as well). We also need to swap DTB or apply a different DTBO at boot time (not compile time) according to a value read from an EEPROM connected through I2…

There is no update from you for a period, assuming this is not an issue any more. Hence we are closing this topic. If need further support, please open a new one. Thanks [image] ccaione: For example sometimes on reboot the I2C DXE driver fails to read the EEPROM again. How’s the fail rate? …

We can read eeprom from an i2c bus as long as it’s specified in dtb.
