[参考译文] LAUNCHXL-CC1352R1：如果未找到 NVM 项、则 OSAL_NV_READ_Ex ()返回成功

https://e2e.ti.com/support/wireless-connectivity/zigbee-thread-group/zigbee-and-thread/f/zigbee-thread-forum/1481131/launchxl-cc1352r1-osal_nv_read_ex-returns-success-if-the-nvm-item-is-not-found

工具与软件：

似乎在osal_nv_read_ex()中的函数中存在问题osal_nv.c。

pZStackCfg->nvFps.readItem()返回时NVINTF_NOTFOUND、osal_nv_read_ex()仍然返回SUCCESS。

或许应该更改  

if ( pZStackCfg->nvFps.readItem( nvId, ndx, len, buf )!= NVINTF_SUCCESS )

？？？
