OTA implementation with BBB + CC2531 (as a Coordinator + OTA Dongle)

Dhanraj

Other Parts Discussed in Thread: CC2531, CC2530, Z-STACK

Hi Folks,

I am using BBB + CC2531 along with ZStack Home 1.2.1. I followed OTA Upgrade User's Guide (This is the only document given by TI for OTA references. I also read OTA Cluster implementation given in ZCL).

I don't want to use Windows based OtaServer Application, I want to use CC2531 as a Dongle iDo I need LinuxGateway Source Code (precisely OtaServer Source Code) for implementing this ? What are my options to implement a perfectly normal OtaServer in BBB + CC2531 setup ? (I shall keep running some scripts on BBB and pull the images to be uploaded to the devices from the Internet, I have used CC2530 as a Coordintor as well)

As I know, there is OTA function implemented in ZigBee Home Automation Gateway reference design. You can read sample_app_ota_readme.txt and Z-Stack Linux Gateway User Guide BeagleBone Addendum in document folder after you install ZigBee Home Automation Gateway reference design.

Can I use external low cost EEPROM ? Why the extension of the images is .zigbee ?

Yes, you can use an external Low Cost 256k EEPROM rather than a Flash. I don't see any special reason to use .zigbee as the extension of OTA image. It's just an file extension.

In reply to YiKai Chen:

Thanks a lot. I am already using the said ZSatck Linux Gateway.

I have the following questions

1. Using the OTA upgrade guide, I am going to create my own OTA client which has On/Off/Level/Groups/Scenes clusters implemented functionality and then compile the Project in IAR with proper build settings, am I going correct ?

2. I am not clear about memory limitations. even SampleSwitchRouter_OTA has considerable size (hex file is of size 681KB, I know that's NOT the size it actually writes on the flash, its in .map we have to see). But With SampleSwitchRouter_OTA with 681KB of hex size, the .map in the source shall show at least around 190KB (I don't know exactly but guessing from hands on experience so far)

3. Is there any document which will explain the ZStack part and bootloader in great depth ?

Thanks for your time.

1. Yes, that's correct.
2. The OTA image would be transmit to CC2530 piece by piece and need to store on an external flash or EEPROM for boot loader to do FW upgrade later.
3. There is no specific document for boot loader.
