Recommended partition`s size (TZ-813) #330

Closed grebenyuk51 closed 7 months ago

Question

In every zigbee sdk`s example there are custom partition table. In those tables always zb_storage partition with length of 16k Is this general recommendation and 16k is more then enough? Or is it make sense increase partition if I plan to connect 100+ devices to my router? Same question about zb_fct Thanks!

# Name,   Type, SubType, Offset,  Size, Flags
# Note: if you have increased the bootloader size, make sure to update the offsets to avoid overlap

@grebenyuk51 ,

Based on the statistics, the basic network information of coordinator will consume about 336 bytes and the coordinator needs to allocate approximately 64 bytes for a new device. You can optimize this based on your project's requirements.

As for the zc_fct partition, it is reserved for manufacturer configuration. You can find more information in the mfg_tool documentation.

By the way, the ESP-Zigbee-SDK stores data in a 16-bit aligned format.
