i am aware I am not the only one but I am sure that I did not make the mistakes that were obvious in the other threads.
I got my Banana Pi yesterday (from Ali-Express) and it included a 8GB class 10 SD Card, a case, a 2A power supply.
I downloaded several images from here (lemaker)..the new Lubuntu 3.0, the 2.0 image, also the Raspbian. I prepared the card with Win32DiskImager accordingly.
I have connected my computer screen via HDMI, put the SD in the Pi, put an ethernet cable in to my 1GBit Switch, attached a USB keyboard and then plugged in the power.
The only thing that happens is that the red led is on and that the LED on the ethernet jack blinks a bit (as expected, there is multicast streams in my network)
No Signal to HDMI. ALso tried the analog TV output later.
I have afterwards tried with 2 more SD card, one of them only 4GB. This 4GB card works however in my raspberry (of course only after flasing another IMG on it)
When I power on without the SD Card, the only difference is that the ethernet jack LEDs do not blink at all.
I have tried 1 more 5V 2A power adapter.
Is there any more ways to debug why it is not booting?
Only thing I did not try yet is to connect something to the UART.
I do also not see any DHCP leases on my DHCP server.
