Hello,

I copied file K8055D.DLL from the folder \DLL_v5.0.0.0 to the \Windows\System32 Folder (i have Windows 7), i connect my Board K8055N with Computer there are no Flash LED8 or something like that… only LED11 (power) lights up.

I try to execute Demo.exe but it’s was not recognized! (Card not found) SK5 and SK6 it’s already connected (adress 0)

What should i do to solve this problem?

Thank you im advance.
Best regards.

[quote]there are no Flash LED8 or something like that[/quote] This indicates that the microcontroller IC3 is not “running”.

  • Please make sure IC3 is in right position.
  • Check that all the pins of IC3 are properly fitted to the socked (no bent pins).
  • Make sure the jumper wire J (next to P8055N-2 label) is installed.
  • Check all the soldering (no solder bridges etc.).
  • Make sure capacitors C1 and C2 are 27pF (labeled 27).
