Original question:
C28xx: Error connecting to the target: (Error -1015 @ 0x0) Device is not responding to the request. Device may be locked, or the debug probe connection may be unreliable. Unlock the device if 烧程序报错 jian'chapossible (e.g. use wait in reset mode, and power-cycle the board). If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 20.0.0.3178) 检查供电没有什么问题，复位引脚恒定为2.08V，被我强制拉高，仿真器连接connection test通过，还可能是什么问题呢，仿真器被锁了吗，这怎么判断呢，有大佬知道吗
