目标设备尚未准备好进行调试

大家好。在PIC调试时，我是非常新的。我正在尝试使用PICIT 3调试PIC12LF1840（3.3V设备）。该设备编程和运行正确，但当我尝试调试时，我得到以下错误：我使用PIC作为主机，通过I2C与一个从DSP（3.3V设备）通信。DSP的数据表要求在时钟和数据线上2K拔出。然而，皮卡3用户指南（第2.4.5节，图2-5）警告时钟线上的上拉电阻将导致调试器不工作。这就是我怀疑这个问题起源的原因。我的问题是，我怎样才能同时使用皮卡3和I2C的ICD特性呢？我希望执行的调试不限于程序的I2C部分，我目前还没有逻辑分析仪。谢谢。

    Hello, guys. I'm very new when it comes to pic debugging. I'm trying to use a PICkit 3 to debug a PIC12LF1840 (3.3V device). The device programs and runs correctly, but when I try to debug I get the following error:

The target device is not ready for debugging. Please check your configuration bit
settings and program the device before proceeding. The most common causes for this
failure are oscillator and/or PGC/PGD settings. Failed getting PC.

I'm using the PIC as a master to communicate with a slave DSP (3.3V device) through I2C. The DSP's datasheet calls for a 2k pull up on the clock and data lines. However, the PICkit 3 user guide (section 2.4.5, figure 2-5) warns that a pull up resistor on the clock line will cause the debugger not to function. This is what I suspect the issue originates from. My question is, how can I use the ICD feature of the PICkit 3 and I2C at the same time? The debugging I am hoping to perform is not limited to the I2C section of the program, and I don't possess a logic analyzer at the moment.

Thank you
