我的重新选择型号，在配置里面的debugger里面的download 选择 use flash loader。可以使用了。
IAP(in applicatin programming):可以自己定义传输协议,自己写bootloaer,用户可以随意更改。上位机自己开发,传输硬件可以是UART、USB、SPI等,flash区域分为Bootloader区、APP区、backup区。程序上电进入Bootloader区,根据条件是否跳转到APP区执行,或更新backup区程序(更新完毕校验OK就复制到APP区)。boot0=0.如下图。该...
There are non-volatile registers in the Kinetis family flash that store the default protection and security settings of the MCU. These include the registers FSEC, FOPT, FEPROT, and FDPROT at addresses 0x40C - 0x40F. IAR, like many toolchains, has added protection against program...

因为MCU只有一套中断向量表,是固定在memory map的一段空间内,在实现OTA时,中断向量是在boot区,而一般在调用self programming库时为了避免中断打断flash的擦写,需要禁止中断。只有在跳转到user区时候,才能正常使用中断。 由于boot和user是独立的project,如何在user区使用中断呢? 这就需要在boot和user中各做一套中断向量...
