Our engineers just generated a DD image that can be used in Ubuntu.Please try the following link to download it: http://pan.baidu.com/s/1gdCdE0N
This link is a Cloud storage website at China. Once you enter the webpage, click the "下载(530.2M)" on the top right corner, and then select "普通下载" in the pop-up window。The downloading should start then.
After painful download process (it lasted really long time), here is what I have:
After burning the image to microSD card and inserting it into the pcDuino, TX LED is, at first, blinking slowly (as it is upgrading the kernel), and then it starts to blink fast, without stopping. I am already waiting more than an hour, so...
Of course, nothing happened and nothing is shown when I try to boot up (without SD card in pcDuino).
Another thing that is quite confusing is that on this image is written pcDuino3B, not pcDuino3.
Previous process, when dd method is used in Ubuntu was like this:
Firstly burn the kernel image on microSD card, update the kernel and then insert the USB or microSD with Ubuntu image and update.sh script on it.
However, on the attached link there is no kernel image nor the update.sh script.
