Hi Phil,
It seems that it is the issue of the SD card you shipped. I replaced that card with my sandisk which is working now.
I think the SD card you provided is too thin so that the pins do not contact properly in the slot in the RB Pi. My sandisk card is much thicker and after I plug it in, I can feel solid contact. Anyway, thank you for your help. I can see it's hashing at 415G/s but for your default BTC address, will switch to my address and see.
Awesome, Glad to hear it! Is the original SD card we shipped actually a "no name" Micro SD inside an adapter with the Raspberry Pi logo on it? We got those specifically because they are "official" RPI cards, so they'd be the most likely to work well, but it's turning out that they stink. We'll test some different ones for the next batch.It seems that it is the issue of the SD card you shipped. I replaced that card with my sandisk which is working now.

BTW, any time you build a new image, the first time it boots, it makes a new bitcoin wallet (viewable on the "wallet" page of the web UI), and begins mining with that wallet. Be sure if it made any BTC that you don't forget to collect it! If you make a backup from the settings page, the wallet is also backed up and restored. If you want to change to a new wallet or mining username, that's done on the "pools" page of the web UI. If you ever restore from a previous backup, it puts all your original settings in, so it's a good idea to make a backup once you get things dialed in like you want. (In case an SD card dies or something.)

Hi Phil,
Yes the defective SD card is the default RB Pi card with the log on it. I can not say it's the card's issue because it works fine on my computer, I think it just does not fit well with the slot in the Pi. But the fix is definitely use a thicker card.
I don't really understand the collection from the default wallet? Do you mean there is a default wallet created on the Raspberry Pi and there could be BTC already generated during the test? In my case cause I have never get original card boot successfully, and just created new card from downloaded image, does that mean I lost the original wallet already? And I also don't understand how to use that wallet and transfer the BTC out? Is there a wallet application on RB Pi? Or I just recover this wallet on another computer using the key pare? Thanks!
