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。
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...
KEIL出现error:Flash Download failed - "Cortex-M3" 安装完器件要下载烧录程序的时候,发现error:Flash Download failed - "Cortex-M3" 这个是因为这里没有选择flash programming algorithm,但是这里没有对应型号的文件可选,原来这个文件在下载的pack中,但是软件没有自动加载,需要到软件的安装路径下面搜索.FLM文件,...
IAR Embedded Work Bench IDE is used for programming MAXQ core-based microcontrollers. IAR™ C compiler (for MAXQ microcontroller) provides the option to define data objects or variables in the flash or SRAM locations. The compiler has special keywordspragma locationandpragm...
烧写就出现The Flash Memory Read-out protection (内存写保护) 错误。 废话少说: 要解除写保护,先仔仔stvp工具点击打开链接 打开stvp工具后: 选择option byte 选择关闭写保护,如果默认是关闭就不用管 然后点击右键选择program current 重新烧写一次,然后重... ...
Check the flash memory block size (the smallest erasable unit of the flash memory). The divide between the bootloader and application must be on a flash block boundary, otherwise you risk erasing parts of the application or bootloader when you replace one of them. ...
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?

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...
