    Is it booted from SD or NAND?

    I have seen this link. However, after cloning NAND to SD and restarting, my result of 'df -h' is different from both photos in the tutorial (my output is here). I think that my pcDuino booted from SD. I have two reasons. First one is that /dev/mmcblk0p1 is listed on the output of 'df -h'. Other reason is that when I run board-config.sh, I have no option to clone my system to SD card anymore. However, I would like to hear your opinion, is it booted from SD or NAND? Also, why the output I have is different from both outputs in the tutorial?

    64GB SD Card

    Is there anyway to use a 64GB Micro SD card with this unit? I was able to get an image onto a card, but it just came up with the pcDuino Display on a white screen, no boot nothing. I don't have a 32gb one and was hoping this would work like you can do on the Raspberry PI's. Thanks. I just got one of these and one of the pcDuino4 Nano's.
  3. This is using Android 4.2 Bootable SD image for pcDuino3. I used dd in Ubuntu to write to the 32GB card in usb card-reader in PC. Put the SD card into the pcDuino, apply power and wait for the installation to complete. Choose your language, time, zone, etc and get wi-fi/ethernet working in Settings. Make sure all is working ok. Shutdown, remove power and remove SD card. Put the SD card back in the card-reader and launch Gparted. I have to assume you know how to move/resize partitions in Gparted. The partitions shown will be as in 1st attachment. You will see that there is only 256MiB for the "SD card storage" in the fat16 partition and 1024MiB (512 + 512) for the system/data partitions. In your file manager, copy the contents of the fat16 volume to a temporary folder on your hard drive, ensure you are showing hidden folders, see the 2nd attachment. Using Gparted, format all the "unknown" partitions to ext4, keeping the same size. This is necessary to be able to move/resize other partitions. Move and resize the partitions to achieve that shown in 3rd attachment. Note that the fat partition needs to be recreated as a fat32 partition, because of the 2GiB (4GiB?) restriction on fat16. I resized the 512MiB ext4 partitions to 4GiB each, keeping all other ext4 partitions the original size. Lastly, paste the original fat16 contents back into the fat32 volume. Return the SD card to the pcDuino, switch on. In Settings -> Storage you should see about 4GB in "Internal Storage" and 21GB in "SDcard". Enjoy. Note: quite handy to know that if you remove the SD card, the pcDuino will boot back into the prior NAND image, which in my case is the original shipped Lubuntu.

    using ubuntu 14 nand image

    I downloaded and installed the Ubuntu 14 nand flash image that is available for download. It immediately fixed some crashes and video failures that I was experiencing. So of course, I'm really happy using it. But there are now some things I don't know how to do. - I cloned the nand image to a bootable SD card. But I don't seem to have the full 16G on the card, just the same size as the nand flash. How can I create a bootable SD of the new release that uses the entire cards memory? - The Arduino IDE is missing. On the download page it says that only command line tools are available. Well, that's fine. I usually use VIM and command line GCC instead of an IDE anyway (and makefiles for larger projects). But where are the tools and libraries? I searched with apt and installed arduino-core, but I'm not sure if it's the right package or how to use it. I saw that the IDE came with a lot of PCduino-specific examples and modules, I will need those to move forward with development. In particular, I need libraries to drive hardware interfaces such as Arduino shields. I design hardware, so I will want to study the code and adapt it to my projects.
  5. I've been thinking about NAND and SD storage. The system partition usually has a generous amount of free space, even after development libraries are installed. The main reason for needing extra space is often that the user files (especially multimedia) can get huge. So, how difficult would it be to boot from NAND and retain the system directories there, but mount the /home directory on an SD? What changes would be necessary? How could you make it permanent? I'd really like to try this option. It also has the advantage of increasing the total available space by approximately 2.5 G. Ideas? Thanks
