Howdy, I received a MCB2370 and a ULINK2 recently. I want to try it. After I installed Realview MDK V3.04 to my computer (windows XP), I got a trouble in ULINK2 communication. Here the details. 1. Install Realview MDK V3.04 OK! 2. Plug in USB cable in ULINK2 to computer, computer found this new device and install driver automatically. After that, I can find this Human Interface Devices in windows Device Manager. Open the Properties page for this device. Under General — Location I can find the name Keil ULINK2 which indicates that the ULINK2 adapter is connected properly. 3. Connect 20pin JTAG cable to MCB2370. Jumper is on the J13. 4. Turn on power by connecting USB cable from PC to MCB2370. I can find the program already running in MCB2370 flash. The LCD display " MCB2370 DEMO" and P2.0-P2.7 LED and LCD bar graph display changed when I adjusted POT1. It looks board works fine. 5. Run "Keil uVision3" and load your sample project BLINKY to uVision3. I can build BLINKY without error. Select Project -> Options for Target 'LPC2378 Flash' dialog. Open Debug section, then select the ULINK ARM Debugger as the Flash-programming tool. When clicking the Settings button to open the Flash Download Setup dialog, I can find MCB2370 was resetting. In ARM Target Driver Setup section, I found Error display "JTAG Communication Failure" in JTAG Device Chian section. Also, I can not find "Serial Number", "ULINK Version", "Device Family" information in ULINK USB-JTAG Adapter section. 6. When I select Flash -> Download, an Error block appears with "JTAG Communication Failure". At this time, I can find "COM" blue LED is on in the ULINK2. After clicking "OK' button, blue LED is off. 7. I already checked some topic about ULINK communication Failure in Keil WEB and changed jumper position from "ARM" to "3.3V" in the ULINK2 board. But it is no use.
Would you help me to solve this problem?
Thank you very much.
