Marlin 1.1.5

[Roberts_Clif]

I revert to the Previous version of Marlin-RC8BF-HICi3 it works Perfectly.

Marlin 1.1.5 using M500 causes CRC errors.

Marlin 1.1.1 - Marlin 1.1.5 using M500 causes CRC errors.
Not an error, looks like it is just a Cyclic Redundancy Check that is stored with the data for testing.

configuration_store.cpp

// Report storage size
#if ENABLED(EEPROM_CHITCHAT)
SERIAL_ECHO_START();
SERIAL_ECHOPAIR("Settings Stored (", eeprom_size - (EEPROM_OFFSET));
SERIAL_ECHOPAIR(" bytes; crc ", (uint32_t)final_crc); //Example "Settings Stored bytes; (451) crc 42816"
SERIAL_ECHOLNPGM(")");
#endif
------------------------------------------------------
#define EEPROM_WRITE(VAR) write_data(eeprom_index, (uint8_t*)&VAR, sizeof(VAR), &working_crc)
#define EEPROM_READ(VAR) read_data(eeprom_index, (uint8_t*)&VAR, sizeof(VAR), &working_crc)
------------------------------------------------------
const uint16_t final_crc = working_crc;
------------------------------------------------------
EEPROM_READ(stored_crc);

Reverted back to Marlin 1.1.5
