ICD 4调试在没有警告的情况下重新启动

你好！我买了一个ICD 4几个月前，因为我炒我的ICD3工作得很好。自从我开始使用ICD4以来，我调试了很多问题。1）它经常在没有警告的情况下重新启动。2）如果在启动调试设置时设置了超过3个断点，那么MPLABX挂在“设置项目断点”3上。调试工具已经出现。该工具将尝试暂时恢复。“调试时，我得到很多。我记得在使用ICD3时遇到了一些问题，但在任何地方我都能看到ICD4所看到的问题。为什么会这样？有没有办法升级ICD4固件，这会有帮助吗？我不能继续这样工作……（我使用MPLABX V4.05，XC8 V 1.34编程PIC18F70J11和PIC18F26K20，我已经尝试了由USB供电的ICD4，由电源供电）/比约恩

    Hello!

I bought an ICD 4 a couple of moths ago since I fried my ICD3 that was working well. Since I started using the ICD4 I have a lot of problems debugging.
1)every now and then it restarts without warning.
2) If I have more than 3 breakpoints set when initiating a debug settings then MplabX hangs on "setting project breakpoints"
3) I get the following message "A communication error with the debug tool has occurred. The tool will attempt to recover momentarily." while debugging, and I get it a lot.

I remember having a few problems when I was using the ICD3 but anywhere close to the amount of problems that I see with the ICD4. Why is this? Are there any way to upgrade the ICD4 firmwars, and would that help? I can't go on working like this..

(I'm using MplabX v4.05, XC8 v 1.34 programming PIC18F87J11 and PIC18F26K20 and I have tried the ICD4 powered by USB and powered by a power supply)
