Marlin [BUG] Marlin on BigTreeTech SKR PRO can't be configured to use the onboard SD-card

Description

Bigtreetech SKR Pro control board(STM32F4) does not seem to hold SD-based EEPROM to the on-board card.

Steps to Reproduce

  1. Load lastest Marlin 2.0 to SKR Pro
  2. Make change via LCD to z-offset, etc, and Save to EEPROM
  3. Power cycle board. Settings have now reverted to initial(firmware) values

Expected behavior: Settings to EEPROM should save between power cycles

Actual behavior: Settings revert to initial firmware values after power cycle Configs.zip

That's a useful answer
Without any help
