4.3 FIRMWARE UPDATE
If it isn’t already installed, run the EM8500 DevExplorer setup and plug in the hardware at least once, so drivers are
installed.
The installer has created a firmware directory for you, from which all subsequent steps shall be performed.
Note:
Firmware loader requires installation of MS Visual C++ Libraries which are commonly installed on PCs. If these are
not installed on your PC, you may either download them from Microsoft or install the full Flash Loader Demonstrator
package from ST Microelectronics, part number STSW-MCU005
Follow the steps below to update the firmware.
ƖConfirm that the DevExplorer is closed.
ƖNavigate to the EM8500 DevExplorer start menu entries.
ƖClick on “Firmware Loader (Third-Party tool)” “Flash Loader” to start this tool
ƖAll settings except the COM port are already preset. To identify the correct COM port, use the Device
Manager and check the corresponding “USB Serial Port (COM x)” used.
Select the correct port from the drop-down-field Port Name:

The IPS Base board connects the PC to the EMDVK8500 daughter board through USB. The IPS base board contains a
microcontroller (Main MCU) to perform several tasks:
ƖCommunication to the PC (USB)
ƖCommunication to the EM8500 (support for I2C and SPI bus)
ƖADC acquisition (MEAS.)
ƖSwitch and relay control (CTRL)
The EMDVK8500 daughter board is the core of the harvesting system based on the EM8500 device. It features:
ƖSwitches for connecting the harvester source (HRV), the storage elements (Short Term Storage STS - Long Term
Storage LTS)
ƖConnections to the loads (POWER and POWER_GROUND).
ƖSome access to the voltage nodes monitored by MEAS.
ƖMultiple access to the different nodes of the system and shunt resistors (for current or power analysis) for HRV,
LTS and STS
ƖJumpers for configuration
ƖOn board default HRV, STS and LTS with spare position (STS)
ƖAdditional expansion connector to connect external HRV, STS and LTS.

The application board is the application load of the system. The application board implements an EM6819 8-bit low-power
microcontroller, an EM9301 2.4Ghz Bluetooth Low Energy Controller, push-buttons and LEDs able to implement various
types of low-power applications. The application board can also be removed and replaced by another application board or
the user can connect external elements to the application headers.
Due to its modular architecture and flexible design, the EMDVK8500 is a very versatile system and as such offers a lot of
possibilities to the user. The following operating modes are offered to the user:
5.1 CONFIGURATION MODE
In this mode the Base Board is connected to and powered from the PC over the USB connection. The EM8500
SPI/I2C interface is connected to the Base Board Main MCU and the Base Board can access the EM8500 registers.
The application board is disconnected from the EM8500 lines (Application board doesn’t need to be present). In
this mode the ADC acquisition can be performed.
