Hi 

    The situation happened after flashing software for MD4-7.   I can't link to MD4-7 via CAN or Ethernet now that means i can't flash software again.  The system still appears images but it will enter blue screen state like photo if i sent some commands to MD4 by any CAN channels.  I try to shortly connect address PIN to enter safety mode but seems no influences.   Who has any suggestions for me to solve this issue ?  How to re-flash software MD-7 ?

To bypass the application, remove the IdTag and power up the MD4. 

Alternatively, you could also short the IdTag and then power up the MD4. 

Thanks a lot.  The problem has been fixed by your suggestions.  But i still confused what was causing it.  The problem just happened after some images of software were replaced by different size images.

Good to hear you managed to recover by powering up without the IdTag. 

It sounds strange that a change of images would cause this. Do you have any warnings on images or display pages in the IQANdesign project check?
