    I have got project from china which uses mini2440 friendly arm
    http://www.friendlyarm.net/products/mini2440

    It do some specific tasks & works fine. I don;t have access to internal code.

    1. After sometime touchscreen TFT misbehaves. I press at some point & it responds at other. Basically it needs calibration. Chinese vendor added password to tft calibration setting. I asked him but he further buys it from somewhere else & couldn't respond.

    Can I calibrate TFT without affecting the main code inside it.


    2. Can I add equivalent TFT with large size without affecting code & display.
