LAUNCHXL-F280049C: 我的开发板本来是可以正常使用的,不知道为什么就出现了以下错误代码,仿真器连接测试是可以的,就是程序烧不进去

Part Number: LAUNCHXL-F280049C
Other Parts Discussed in Thread: UNIFLASH

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 possible (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 9.3.0.00058)
