Module firmware updates
5.1
NORA-B1
The application on NORA-B1 can be updated through the MCUboot bootloader over UART. Each new
image is uploaded to the XPLR-IOT-1 QSPI flash prior to writing it to the NORA-B1 flash.
5.1.1
Bootloader
–
batch file
1.
Download the new application core and network core firmware images and the
newtmgr
utility
from the main XPLR-IOT-1 main repository
☞
If there are no updates to the network core, there will only be an application core file.
2.
Start bootloader mode by pressing and holding button 1 while resetting or power-cycling XPLR
IOT-1.
3.
Determine the COM port number for NORA-B1 on Interface 0 of the USB-UART interface (e.g.,
COM 15). This example assumes the example COM port enumeration of interface 0 shown at
USB connection.
4.
Open a file browser and navigate to the folder containing the firmware images.
5.
Double-click on the batch file
Update_XPLR-IOT-1.bat
6.
When prompted, enter the COM port number (e.g., COM15).
7.
When the update completes, press any key to close the window.
8.
Reset XPLR-IOT1 (reset button, power switch, or command line:
nrfjprog
–
-reset
)
5.1.2
Bootloader
–
manual update
1.
Download the new application core and network core firmware images and the
newtmgr
utility
from the main XPLR-IOT-1 main repository
☞
If there are no updates to the network core, there will only be an application core file.
2.
Start bootloader mode by pressing and holding button 1 while resetting or power-cycling
XPLR-IOT-1.
3.
Determine the COM port number for NORA-B1 on Interface 0 of the USB-UART interface. This
example assumes the example COM port enumeration of interface 0 shown at
4.
Open a Windows command prompt.
5.
Navigate to the folder containing the firmware images.
6.
Update the network core (optional, depending on the requirements of the update)
newtmgr.exe
–
-conntype=serial
–
-connstring=
”
COM8,baud=115200
”
image upload
net_core_update.bin
Replace
net_core_update.bin
with the actual filename of the downloaded network core update.
Replace
COM8
with the actual COM port on interface 0.
7.
Update the application core
newtmgr.exe
–
-conntype=serial
–
-connstring=
”
COM8,baud=115200
”
image upload
app_core_update.bin
Replace
app_core_update.bin
with the actual filename of the downloaded application core
update. Replace
COM8
with the actual COM port on interface 0.
8.
Reset XPLR-IOT1 (reset button, power switch, or command line:
nrfjprog
–
-reset
)
⚠
If updating the network core, both the network and application cores must be updated during the
same bootloader session. If updating only the application core, the network core update can be
bypassed.
☞
The update sequence listed here assumes the availability of pre-configured binary files. Custom
application code may also be updated through the bootloader. Additional details may be found in
