Hi, i have a LPC1114F/302 based board(footnote 1). I was initially trying to control a GPIO pin, without success. And when i checked the registers, they where all filled with junk, even if i reset the target, the values of the regs stay. Now i am simple trying to put a value into r0: MOV r0, #5 . Though when i download the code nothing happens. My OS is linux mint 17.1 64bit, and im using the fasmarm assembler.
Here is my procedure:
$ sudo JLinkExe
