CC1352P: OAD Split image support

Bill Kuckuk

Part Number: CC1352P
Other Parts Discussed in Thread: CC2530

Currently, the zct_ota declares an image invalid if not combined ( != OAD_IMG_TYPE_APPSTACKLIB).

Are there plans to support a split APP/STACK on this platform (OAD_IMG_TYPE_APP)? This would reduce the .zigbee image size and save update time/$$$.

Thanks,

Hi,

There are no plans to support a split App/Stack.

Regards,
Toby

Is there any guidance on how to reduce the size of the image? The sample (simple) zr_sw_ota_client is over 220K and takes over 10 minutes to update OTA!

Some things to consider:

- make sure optimization level for size is 4 (this is default in the zstack example projects)

- make changes to the oad_app.cfg so that it uses the release configuration of TIRTOS (explained in point 1. here).

- some considerations which are used for decreasing memory footprint for CC2530, but also applicable in general are found here

Hi Toby,

Using the correct oad_app.cfg file helps. Decreased the size about 10%. But still 20% larger than the CC2530 that we're porting from.

Thanks for the help.
