TM4C123AH6PM: UniFlash芯片烧录锁死

Part Number: TM4C123AH6PM
Other Parts Discussed in Thread: UNIFLASH

使用TI官方的UniFlash+XDS110正常烧写软件,之前都一直未出问题。最近频繁遇到“Error -1170 @ 0x0”错误无法再次烧录。网上搜索说是芯片进入生产模式了,需要进入开发模式才能烧录。但是找了一圈也没有找到可行的进入开发模式的方法。在此恳请各位大牛指点迷津...

错误原文:

Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device,and retry the operation. lf error persists, confirm configuration, power-cycle the board, and/or trymore reliable JTAG settings (e.g. lower TCLK). (Emulation package 9.3.0.00042)
