No boot

5 3834
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.
ok now i got UART with more information:

question is why does this happen with several SD cards....any other way i could prepare/verify a card?

It is SD card problem.  The SD card may have some broken blocks. But most problem is the actual SD card size is less than the image size.

I had exactly the same error with 2 separate 16Gb SD cards, and then the 3rd card I tried worked perfectly!

Try to format card with SdFormater tool.(with flags: file adjusment on, quick format on) I also had problem with SD, but after formatting with this tool - everything ok.
