Before install logicport from www.pctestinstruments.com , I can connect to my board, but after installation, I can't. What is wrong?

You mean there is a conflict between two USB devices:

1. CCS ICD-U40 (or ICD-U64).

2. Logicport Logic Analyzer

This page has analyzed the LogicPort. They say it has a FTDI FT245BM
USB chip on it:

With this information, you can now search for articles in the CCS ICD
Programmer/Debugger Forum. You can search that forum for

I run the same setup. The LogicPort is programmed correctly and plays nicely with any other FTDI device. The ICD is programmed incorrectly and only looks for the first FTDI device it finds (which will never be the right one (Murphy's Law).

So I just unplug the Logic Port when I need to program or debug. It will complain after a minute or so but it will work again on reconnection (does not crash).

And as PCM recommends - always keep the ICD driver install program on your PC. You will need to install the driver often over the years.
