 ===Serial number is not present on the board===
 On Recore A6 and A7, the serial number and calibration data is stored in a special hardware boot partition on the eMMC. This partition will not be removed during a complete eMMC erase. For Recore A5, the serial number is written on the bottom of the board. Now that there are multiple versions of the hardware, some additional steps are taken as part of the flashing process to set the right device tree and Klipper config file for the hardware revision. For Recore A5, you will need to set the serial number manually.
