Dear experts
我在用tms570ls1227作bootloader功能,我从网上找到了例程 processors.wiki.ti.com/.../TMS570_Hercules_MCU_Bootloader
第一个问题是,这个压缩软件的doc文件夹是空的,我找不到关于它这个例程的任何资料。
第二我发现网址上有这句话 After HDK reset, the start-up code copies the Flash API of boot loader from flash to SRAM, and execute the boot loader in Flash.
将 f021从flash拷贝到 sram里面, 我想问这是必须的嘛? 为何这么做?怎么做?
第三 我在SPNU501G 里面看到 API functions require execution in privilege mode. 那么问题来了 必须进privilege mode吗?怎么进?
还有这句话:The F021 Flash API library cannot be executed from the same bank as the active bank
selected for the API commands to operate on. On single bank devices, the F021 Flash API
must be executed from RAM.
1227和0432都是flash只有一个bank bank0 那么F021 Flash API 一定给拷到ram里面了?
Any answer is appreciated,thanks
