I have installed PE Micro Drivers. I do note that in my device drivers under Jungo, I only see one listing, that of WinDriver. Someone else told me they had two entries under Jungo. When I bring up my IAR ARM V6.50.2, load an example program made for IAR (pwm_led) and try to move to debug, I get an window telling me "port: Undetected. Disconnect/Connect USB cable. Click Refresh List." No matter select after this, I can not connect. I am sure I have the latest drivers from PEMicro. Anybody have this problem or an idea how to fix it? I am plugged into the SDA connector. My PC does recognize the KL25Z as an SD card and displays the directory. The green LED is flashing at about a half second on and half second off. The multicolor LED changes color when I move the KLZ25 as expected.
