Raspberry Pi 0 W - no image #11

Closed jahevos closed 3 years ago

jahevos commented 3 years ago

I cant get the image from my raspberry pi 0w dpi_video out. Basically I am stuck with the nebra startup screen. I tried this under a number of distros - libreelec,kodi,raspian and raspberry os. I get, however, a proper image when setting it up with a rpi 2. I tried all of the suggested config methods from the user guide but to no avail. Also no matter which power supply and usb wire I use I do get a yellow flash in the top right corner. Any Input would be appreciated - maybe anyone else ran into these kind of problems.

cheers J

Hi @jahevos ,

If it's where it works with your Raspberry Pi 2 fine with the same SD Card image as you're trying on your Zero I would suspect it could be a faulty Pi Zero W.

Did you buy one with the header pre-soldered or did you solder it yourself? It could be one of the joints isn't quite good enough for the signals required for the HAT.

Hi Ryan thanks for your quick reply. I got a pre-soldered pi, so it should be okay but I will look into it later. Cheers

That should be fine then. If you could take a picture of the header I can see if there's any visual defect with it but it would be odd if it's pre-soldered.

Hi Ryan,

I gave everything another go, with no success. I'll get another pi zero and see what happens. I'll keep you posted on the outcome. Best j
