Hi I have updated Keil for ARM from 3.00 to 3.01.When I try to download program to LPC2142's internal RAM and Debug,I recieve an error messange box: uVision3 IDE Error you should shutdown the application. There is no error when I download program to flash and debug. After I replace The SARM.dll (version 3.01)file by 3.00's(vesion 1.52),the error messange box never occur.
