Apparently,  I damaged my first LPC1342, by a false contact in the lines of  programming (SWDIO, SWCLK), but I found that I can enter ISP mode, and tried  unsuccessfully to load a program (USB bootloader).

Performing post-build steps
arm-none-eabi-size LPCXpresso1343_blinky.axf; arm-none-eabi-objcopy -O  binary LPCXpresso1343_blinky.axf LPCXpresso1343_blinky.bin; checksum  LPCXpresso1343_blinky.bin;

I renamed the file to "firmware.bin", and copied to the microcontroller.

I tried my trusty LPCXpresso LPC1343 board, and the result is the same. [B]Apparently the program is invalid.[/B]

What I am doing wrong?

Thank you very much for any help!
