Cpu Error 2

[Whinis]

so i started to learn cpu as it figured high speed devices might be fun. I loaded up a test program ( 3 infact) and all produced 0 errors however did not work i tried testscreen1 and testscreen and hello world. so i figured i must be doing something wrong.

next I made a simple cpu program

Start:
in eax,0
mov ebx,eax
out 5,ebx
jmp Start

however every time I run it I get error 2. so I tried reset clicked the cpu again so that I was sure that the program uploaded and tried it again with same results. repeat 10 times and still no results am i doing something wrong ?

Check your console. Does it say anything about any error there?
Are you sure you have wired everything up correctly? Did you press enter and load file after writing in the file name? Did you use the .txt file extension in your file name when loading?

well i wrote the file through the ingame code editor and no no console errors.
and as for wireing simple screen connected toPort0 to A and A button to Port5 and B on screen. I/Obus to port 0 on dataport. clk to a separate toggle button. reset to a non toggle button all buttons have 0-1.
