Tool/software: WEBENCH® Design Tools

I have create my coordinator program and set its ZDSECMGR_TC_DEVICE_MAX value into 200, coordinator could generate a network with nwk-key is {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}. And then reduce this value into 128, it can generate a network with correct nwk-key, but it can't restore Network from power up.

I have proved that large ZDSECMGR_TC_DEVICE_MAX setting will cause some others NVs written failed. Is there any way to setting larger ZDSECMGR_TC_DEVICE_MAX ?

Hi Team,

I can reproduce this issue. A large ZDSECMGR_TC_DEVICE_MAX setting will cause some others NVs written failed and can't formation network. Once, Coordinator can formation network, but can't reply zed "Request key" command. Please help use resolve this question.

I have try to increase the NV-RAM size, but it is no use. I have set the "Region Base" to 0x4E000 and "Region Size" to 0x8000, but NVs written is still failed.

Hi Aries,

You are encountering a well known SIMPLELINK-CC13X2-26X2-SDK NVOCTP driver limitation which will be improved in v3.30, but until then you cannot increase ZDSECMGR_TC_DEVICE_MAX or other macros expansively as this will exceed the current one-page NV memory restriction.
