hi:
I have been writng code and test it on IAR evb with lpc2468 a few day. But after I download
code to the board this morning. My J-link lost communication with the MCU. I did learn some
from Forum today and knowing what casue the problem and tried to fix it by your J-FLASH
software. well, I am sorry that I still can not make J-LINK to connect to MCU. MCU is running
with no correct setting PLL or RCTK. How can I let your device (J-LINK) control the ARM cpu?
Is there any easy tool to ereas code in flash of MCU ? I do believe that a lot of people facing
same problem as I have today

Thanks

Steve Tian
