I have weird situation on LPC1768 microcontroller. I have copied project software from original to new folder for backup needs. I compiled the copied program with uVision4 and download it to uC via ulink2. The flashing process is stopped at 70% and uC stops working. The uC doesn’t response to reset anymore. The Bootloader doesn’t start up (tested with Flash Magic). Some pins stay at 3.3V when the reset is activated. I have tried this on 3 uC, 100% software problem. Tested on Keil MCB1700 too. Can I destroy the uC with software? This problem disappear when I have replaced startup and configuration file.
