UPDATE 1

I tried to connect the UART to my USB to ttl converter during boot and now I can see all mesages and login prompt. Seems working ok but still no HDMI output. I alredy tried to tweak the output with all available mode on tvservice command but both my monitor and my tv shows no signal.

I've bought a month ago a new Raspberry Zero to try this little toy. I'm already playing with a Raspberry and linux OS in general but this time i'm very close to give up. The problem is that this Raspy won't display boot messages, this is what i've tried: - Change SD card - Fresh NOOBS install - Old SD from pi2 with jessie raspian ( this give 7 green led flashes ) -

  • 16gb with NOOBS v1.5.0 image (boots on pi2)
  • Same 16gb card with raspian jessie image (2015-11-21 and also this boots on pi2)
  • Old 8gb SD from pi2 with jessie raspian ( this give 7 green led flashes )
  • .txt file to force HDMI hotswap and other commands video-related (copied below)
  • HDMI to DVI cable
  • HDMI to HDMI cable (actually I've tried 2 of them)
  • Different monitor or TV
  • With or without micro USB to female Usb adapter to connect a keyboard

here is my config.txt file to force HDMI hotswap and other commands video-related - New HDMI cable - Different monitor or TV:

What else can I try??hope to have been detailed as possible, unfortunately with mi first RPi B and the RPi 2 i've never issued this kind of problem.
