cc3220sf 的SOP2接下拉电阻仍为高?采用XDS200进行调试报错Error connecting to the target: (Error -242 @ 0x0) A router subpath could not be accessed.

(1)自行设计的cc3220sf 的SOP2接下拉电阻2.7k仍为高3.3v?测了下CC3220SF-LAUNCHXL板上SOP2上电后也为高(未接跳线),默认不该是低吗?

(2)采用XDS200进行调试报错

Error connecting to the target: (Error -242 @ 0x0) A router subpath could not be accessed. The board configuration file is probably incorrect. (Emulation package 6.0.576.0).该如何解决呢?

换了CC3200SF-Launchpad上的JTAG接口,出现如下错误。何解?

Error connecting to the target:(Error -1170 @ 0x0)Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).(Emulation package 7.0.48.0)

回复 Terry Han:

SOP1我按照开发板设置接了高电平。SOP2接了下拉电阻,仍为高电平。SOP0为低。

da qin zheng sheng:

可以设置为标准swd方式,通过sop2,sop1,sop0设置。

da qin zheng sheng:

使用ccs还是iar?

回复 da qin zheng sheng:

CCS7.3.

SOP2上电为高,2.7k对地,电压3.3V.

换51欧姆对地,电压为1v。

不要下拉电阻,直接对地短接?
