433M下,选择输出功率12dbm,软件可以正常编译,正常收发数据;选择13.7dbm,而且修改了,软件编译正常,仿真时提示无法进入DAP错误,能发送几组数据,以后不能正常。请问还有什么需要更改的吗?

SDK版本为。
错误提示为:Cortex_M3_0: Error: (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 9.3.0.00058)
Cortex_M3_0: Trouble Halting Target CPU: (Error -2064 @ 0x0) Unable to read device status. 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 9.3.0.00058)
这个错误在选择发射功率大于13时,就会出现;小于等于12时,不出现。如上一个帖子所示,已经修改vddr_hh 为1,但是错误仍在。如果是硬件问题,应该不是复位等问题吧,433M电路参数也是按照手册给的。这个问题一直困扰,项目不能推进。
帮忙看一下吧
看了上面的原理图,射频前端部分没有问题
vddr的电压刚上电是1,92v,然后是1,67v,应该也正常
这部分有些问题,启用了CCFG_FORCE_VDDR_HH = 1后VDDR电压应该是1.95V,这样才能启用boost mode高功率
电源供电部分或者仿真器可能也有问题
建议购买一块LAUNCHXL-CC1350-4开发板进行测试,上面带有板载仿真器,可以快速排查硬件设计和仿真器问题
