28377s不能烧录

,但是Test connection 测试连接成功,烧录时提示芯片未应答,或都芯片锁住,但是几块板都是一样,我相信不是芯片问题! 现在无头绪,求思路

Seven Han:请问板子是TI的还是自己设计的呢?具体的提示信息有哪些?使用TI的例程测试了么?

不是, 是自己做的板子! 例子可以烧录到其他的项目的板子,
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 7.0.100.0)

您的板子和其他项目的板子原理图是一样的吗?您的工程在烧录其他项目的板子时,使用的ccs,仿真器等都是一样的吗?
