I got the excellent answer for my initial question @ https://community.cypress.com/t5/Wireless/CYW20735-Memory-Map/m-p/276969#M566 But I am still in doubt where the SPI Flash range is mapped to. From the moderator's answer to my previous post I understood that the map at https...

查看map文件,image_watch_seconds这个数组已经被分配到了0X90138690这个地址了,这个地址正是LR_EROM1 所在的区间。 Part3二、MDK下载算法原理 1程序能够通过下载算法下载到芯片的原理 通过MDK创建一批与地址信息无关的函数,实现的功能主要有初始化,擦除,编程,读取,校验等,然后MDK调试下载阶段,会将算法文件加载到芯片...
