https://devzone.nordicsemi.com/f/nordic-q-a/68384/zigbee-cli-example-flash-areasWhen I program the Zigbee cli example from T&amp;Z SDK v4.1.0 I see that the Zigbee stack uses some flash areas at the end of the chip. In my case 304 bytes @ 0x000F7000 and 24 bytes @ 0x000FB000. I would like to change the location of these two areas, becauseen-USTelligent Community 13Mon, 16 Nov 2020 14:12:20 GMThttps://devzone.nordicsemi.com/thread/280131?ContentTypeID=1Mon, 16 Nov 2020 14:12:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0fd8cdbe-856b-418c-a4bd-3b4713a91761Marte Myrvold<p>Hi,</p> <p><span>You can change size of the persistent data area by modifying&nbsp;</span><code>ZIGBEE_NVRAM_PAGE_SIZE</code><span>&nbsp;and&nbsp;</span><code>ZIGBEE_NVRAM_PAGE_COUNT</code><span>&nbsp;configuration options in the&nbsp;</span><a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/sdk_config.html" rel="noopener noreferrer" target="_blank">SDK configuration header file</a><span>.&nbsp;The persistent data is stored close to the end of flash memory, as described in&nbsp;<a href="https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/zigbee_hw_and_mem.html#zigbee_hw_and_mem_memory_layout">Zigbee stack memory layout</a>.&nbsp;For details, see&nbsp;<a href="https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/zigbee_mem_cfg_feature_flash.html">Zigbee stack flash usage configuration</a>.</span></p> <p><span>Best regards,</span></p> <p><span>Marte</span></p><div style="clear:both;"></div>
