 = Flashing Firmware
 
+To flash the firmware, you first need to update the configuration file that stores the informarion specific to this box and then flash the rebuilt firmware to the box.
+
++ Update the file in `base-firmware-new\application\src\aa_set_device_parameter_here.h`
+    + Change the `SAS_KEY` value to the connection string from the IoT Hub.
+    + Change the `AZURE_DEVICE_ID` field to the Id of the box from the label.
+    + If needed, change the `MCU_DEVICE_ID` field to the last three characters of the Atmel chip serial.
++ Save the configuration with `ctrl+s`.
++ Rebuild the firmware with `Build` #sym.arrow `Build Solution (F7)`.
++ Verify that the box is properly connected to both power and the Atmel adapter.
++ In `Tools` #sym.arrow `Device Programming` detect the box as for the base firmware.
++ Under `Memories` in the left sidebar, select the file to flash that end with `V71Q19B_`#text(fill:orange)[`XXXX`]`.hex` with #text(fill:orange)[XXXX] a four-characters hexadecimal number.
++ Click `Program`.
+
+Congratulation, the box is all flashed, you are almost done.
+
 = IoT Hub Setup
 
+Now that the box is flashed, power cycle it and connect it to a PoE enabled port that has internet access.
+
++ In the IoT Hub, under `iothub-eet-dev-001` #sym.arrow `Devices` select the newly flashed box.
++ Access the configuration in `Device Twin` in the top bar.
++ Make sure the field `properties` #sym.arrow `desired` #sym.arrow `enableTransmission` is set to `true`. If not, change it and save the configuration.
++ Access the aggregator configuration in `iothub-eet-dev-001` #sym.arrow `IoT Edge` #sym.arrow `sf-pc48` #sym.arrow `IRF` (bottom section) #sym.arrow `Module Identity Twin` (top bar).
++ In the config, in the `targets` array, add an entry following the same template as the other entries with two fields:
+    + `interceptorId` is the Id of the box (printed on the label).
+    + `targetId` is the name of the MinIO folder where all the data will be stored. By default, enter the same as the box Id.
++ Save the configuration.
+
+The finale step is to restart the aggregator to apply all the changes.
+
++ SSH into the `sf-pc48` server.
++ #text(fill:red)[write command]
+
 = Verification
 
+Go on MinIO and verify that a folder with the name of the box was created and that some data started comming in. If not, good luck debugging this mess (I recomend redoing everything...).
