Q: FAQ: How to demonstrate OAD on CC2430 (ZigBee) by 656199
How do I get started to show the OAD feature on the CC2430?
You will need the OAD flash daughterboard to test the OAD feature with the ZOAD
PC application.You would need at least three boards to successfully show
a demo.1 SmartRF04EB with CC2430 EM for the dongle. An OAD daughtercard
is not necessary but helpful if you use the attached hex file for ZportApp. This
has the OAD bootcode and at startup it will look for an external flash. If one
is not present, it will take a few seconds before it displays “Figure 8 Wireless
NWK device” on the LCD, and the orange LED will also start blinking. This device
acts as the “dongle” that talks to the ZOAD PC application1 CC2430 DB or
EB as the coordinator of the zigbee network1 CC2430 DB or EB as a router
in the zigbee network (this is the device that you will update via OAD) + an OAD
daughterboardOnce you have all this hardware, you need to follow the
instructions in the developer notes that come with the recently updated
1.4.3-1.2.1 installer. These instructions take you up to the point where you
build your downloadable image. The device you will program also needs to be
programmed with a version of the firmware that is “OAD enabled”. The developer
notes take you through this step as well.You then have to connect the
ZportApp dongle and connect it to a USB 2 Serial cable. Depending on the
integrity of your cable, it might take a couple of tries to get the PC app to
load. Once up and running, you will have to scan for available networks, join
the network that you established with above hardware, then join it. Once you
have joined it, you then scan for devices in the network, select the device you
wish to upgrade, then select the .bin file that was created.You’ll then
see a progress bar that will go until you see the message “Store image
complete”. You must then enable the image by pressing the “Restart device”
button. It will take about 20-30 seconds before the OAD bootloader finishes
perform an integrity check of the downloaded image, then resetting the device
with the new firmware. You will then see the router re-associate to the network.
And there you have successfully updated the router using OAD.
