When trying to use the Emulated EEPROM in a PSoC 4 device (CY8C4248LQI-BL483) data always reads back as zero. Is there incompatibility between emulated EEPROM and BLE or Bootloader or bootable stack? If so, what is the workaround for this?

When I run the EEPROM example "PSoC_EmEEPROM_PSOC401", data reads back just fine. But when I add the exact same code to my project with BLE and bootloader, reads return 0.

No that wasn't the issue.  I have seen that in the past an was aware of that.  The issue turned  out to be out the project was using an older version of the EEPROM and BLE components. Once they were updated to the latest version and did a clean rebuild of the projects, bootloader and application, flash writes began to work.
