-The actual low-level driver for operating on the internal data EEPROM is located in the files ''memdrv.c'' and ''memdrv.h''. The implementation of the before mentioned hook-functions is such that it glues it to the function in this low-level driver.

+For testing purposes an extra S-record file was generated that contains random data, mapped to a location in the internal data EEPROM:
+  * \Target\Demo\ARMCM3_STM32L1_Nucleo_L152RE_CubeIDE\Prog\Debug\eeprom_data.srec
+If you select this S-record file when starting a firmware update, its data contents will be stored in the STM32L152RE's internal data EEPROM.
+Note that this S-record file with random data was generated with the ''srec_cat'' [[https://srecord.sourceforge.net/|tool]]:
+<code>
+srec_cat -generator 0x08080000 0x08080400 -repeat-data 0x00 -exclude 0x08080000 0x08080400 \
