RT-Thread使用DAP-link不成功是何原因？

问答对人有帮助，内容完整，我也想知道答案 0 使用DAPLink，发现无法调试，也无法下载，会报如下错误： 0000971 W Overlapping memory regions in file ./packs/Keil.STM32L4xx_DFP.2.3.0-small.pack (STM32L412C8Tx); deleting outer region. Further warnings will be suppressed for this file.

答案对人有帮助，有参考价值 0 我发现问题了，rt-studio带的pyocd0.1.6存在bug，他可能会把stm32f405芯片，知道别为L4系列的芯片，我换了ulink，就可以debug了，然后换了另外一个板子还5上面5 ，daplink也可以使用。现在看来，某种情况下，pyocd不太可靠。
