DA1458x SDK Software Layout 随笔

DA1458x SDK 5.0.4

分层

Dialog在DA14580分层主要分为BLE_stack、kernel、Profile和Application。
其中BLE_stack和kernel使我们不可见的，Profile和Application是我们可见的。
下面是官方的Software Layout

这个图中关于Profile和Application的排布我感觉并排的感觉并不是十分合适。
从内核的角度来开，profile和Application都是依赖于RW内核来创建任务来调度的。在kernel上同一层没错。
但是Profile的TASK等级比Application的等级高。
下图为Dialog RW kernel的任务类型

可见做多任务数为64个，Profile的任务高于TASK_APP。
实际代码中，Dialog在5.0.4版本的SDK中（其它版本没看过），将所有的Application放在TASK_APP中。
并且专门准备了cust1和cust2给用户开发使用。
这些Application都是基于TASK_APP提供的一些API和服务以及系统原有的底层调用来运行的。
官方5.0.4 SDK PDF说明文档里的这个图会清晰一点。但是实际逻辑还是要看过代码才能理清楚。
