So after my initial purchase of the Raspberry Pi Model B (The biggest model, quad core and 1gb ram)
I just cannot make it output anything on HDMI, the microsd card has been swapped and tested on a kncminer that runs a similar raspberry pi, if not in fact identical...
Exactly what model of Pi does the "kncminer" (whatever that is?) use - a P2B is not
the same as the, albeit similar, B+ and needs an O.S. with upgraded firmware!
The Raspberry pi, Powers up, The green ACT led flashes for 20-30 seconds Before it "quiets down", No signal from my monitor, No signal if connected to the TV (The KNCMiner does output to that TV so there should be no incompatibility issues) The powerbrick has been changed between different ones, Modified D-Link powerbricks 5V 2A, the latest one i found was a huge thing, 5V 3A, but the result is the same.... the board seems to boot normally, but no video. i even purchased a 3.5" touchscreen from Ebay just to make sure there were no issues with the HDMI itself, the screen is just all White and nothing else.
The green ACTivity led behaviour is similar to that for a NOOBS image when connected to a display that isn't compatible with NOOBS' default HDMI setting. If you were/are using NOOBS did you try "hdmi safe mode" by holding/toggling key '2' during boot. (NB. an older NOOBS setup that was originally created for a B+ again will not work on a P2B - you need a current version)
So tried 2 different Monitors (PC-Monitor and TV)
Tried atleast 5 different Power supplies
Hooked up a custom mini-display that is made just for the Raspberry pi.
No Rainbow-screen. nothing zip nada.
Board seems to boot just nice. No Video..
Tried The Elec-xbmc, the Another xbmc, Some Linux versions........ just about Everything...
Do i need more than one powersource to make this thing output video ?
Or is this really about me trying to boot from an incompatible distribution.. I have really tried most things now except to try to boot from older images and such..
Suggestions people... Anything would be much appriciated.
Have you actually tried one of the images from the RPi downloads page? (They all should work with a P2B, images from elsewhere may not have been updated by their maintainers)
Also (re-)read through view
Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, A+ and a B2) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm
