A13-SOM-512M problem with boot from SD

[Misiek906]

Hi.

I`v got problem with boot Linux from SD card.
Allays I`v got this same info in UART.
When Times goes to 0 reboot again and again...

I use this same SD card in my RSPI (ADATA 16GB class 10). I my RSPI I do not have problem with boot etc.

Can someone tell What I doing wrong?

You'll need to provide full info like which image, power supply etc.

One of corrupt download / poor SD / poor power?

Maybe someone will post or has already posted (googled it?) what the output should be so you can see where it goes wrong.

Hi.

I thing problem was resolved.

My Power Cable is too thin and can not send  too much peak current.

I've changed power cable and board is running.

Thx for Help:)

Power supply was a problem for me when I started. I did not recognise that and about to send it (a13 board) back. Then I found an old 3.3v 2a supply and it worked  . Even with USB power supply i.e. 5v 2amp throu 'WiFi board' did not work.
