OlinuXino A20 Lime - Red blinking led

[Kimahri_San]

Hello everyone!

I just bought the OlinuXino A20 Lime without NAND.

When I plug it on, the red PWR led blinks continuously and it doesn't power on.
The curious thing is that the led of the power supply blinks at the same frequency of the led on the board.

I already tried changing uSD card, removing ethernet and HDMI cable. The supply is 5V/2.25A bought on purpose and it works perfectly on the RaspberryPi (it has interchangeable connectors).

Can you give me some suggestions?

Thank you very much!

PS: I don't own a RS232 TTL to USB cable to see UART0 output.

Hi,

If you have desktop PC you can supply Lime board using USB OTG. Please check it, it could be problem that your supply source isn't well filtered.

Tried that, but unfortunately it didn't work.

Thank you anyway for the suggestion.

The easiest way is check DEBUG Uart, maybe one of yours friends has converter UART<->USB?

No how many PC did you tried load image to uSD card? It's important because no matter how I tried do it on my notebook card never start working with Lime. So maybe you could check it on other PC?
