5 STM32F401RC 用 RT-Thread Studio 烧写不了程序

STM32F401RC 用 RT-Thread Studio 基于芯片建立工程，编译后在IDE中点击下载按钮，无法下载至MCU，Jlink灯闪了一下就熄灭了，烧写不了程序，供电都是可靠的(外部3.3V供电)。

同样的硬件环境下，用STM32CubeMX建立工程后是可以用Jlink正常烧写的，也能正常执行程序。

同样用 RT-Thread Studio 基于芯片建立工程，创建一个STM32F429IG工程，编译后在IDE中点击下载按钮，是可以烧写STM32F429IG芯片的。基于STM32F401RC 建立就无法烧写STM32F401RC，不知道是BUG还是哪里配置不对？
