iar使用秉火DAP仿真时出现错误 Download error at 0x08000000: downloading into non-writable memory.

在学习野火stm32f103开发板时，iar使用秉火DAP仿真时出现错误 Download error at 0x08000000: downloading into non-writable memory.

错误原因：我在使用cmsis dap仿真时，切换到了右键工程->optiosns->debugger->simulator

解决方法：切换右键工程->optiosns->debugger->cmsis dap，然后debugger->download->选中use flash loaders->选中override default .board file->  设置$TOOLKIT_DIR$\config\flashloader\ST\FlashSTM32F10xxE.board
