How to (re)flash pcDuino (how to (re)install Lubuntu 14) on pcDuino (into NAND) using Windows?

Recommended Posts

Thank you I have Lubuntu 14 running.  It is not Lubuntu 12 so some things do not work the same.

I can not see how to get back to booting from SD card.  How do I make the SD bootable.  I do not see that command under board-config.

AND

The SATA hard drive will not power up.

AND

I can not get back to 1440x900 on the monitor.  It will only work at 1280x720.

To make a bootable SD you need to use board-config.sh utility.

I believe it is [CTRL] [F1] to get to root prompt. Its early and I do not have it sitting in front of me.

Once at the prompt execute "board-config.sh" and in that utility is a selection to make bootable MMC.

sudo board-config.sh does not have a make bootable MMC command like Ubuntu 12 did.  

It also does not allow for different screen size.  

I like the board-config12 and do not like board-config14!

I need python 3, so I changed to 14.  Too many things do not work.

 

I will go back to 12 and try to install python 3.

When you run board-config.sh there is not a "make_mmc_boot" option on the main menu?

 

I just loaded latest ubuntu 14 for pcDuino3B/Nano. Pressed [CTRL] [ALT] [F1] to access root terminal. Executed "board-config.sh" which displayed a selection of things to do. The bottom selection says, "make_mmc_boot              Clone system from nand to mmb card".

Not for me.  The [ctrl][alt][f1] board-config.sh and the terminal sudo board-config.sh seem to be the same.  

No "make mmc boot"

I re-installed Ubuntu 14 and now the "board-config.sh" works!  :)  Now I get Python 3. :) 

With Ubuntu 14 the monitor resolution is automatic not manual.  I can not force it to 1440x900 like with Ubuntu 12.

I can live with that for now.  

 

QUESTION:

df -h

"Mounted on /dev/root   3.5G 1,4G 2,0G......"  

/dev/mmcblk0p1  16M 4.9M 12M............ 

/dev/sda1................

/dev/nandd 3.5G 1.4G 2.0G ............

Am I booting from NAND and not SD card????

Did you try setting the resolution in board-config.sh? Sometimes it works and sometimes not.

 

After creating bootable SD go back into board-config.sh and expand_rootfs.  Also, do set_locale and it will remove the extra languages and free up room as well.

 

Scratch that:

I remember needing to use another program to expand rootfs successfully.

 

Let me test and I will report back.

 

Edit:

I am going to create a separate discussion and perhaps put it in tutorial.

No "make mmc boot"

I noticed that board-config.sh some times has "make mmc" and some times does not.

I now know (on my system) it depends on the SD and hard drive and how they are formated. 

Formatting or unpluging the hard drive or SD card changes things.

If you just need Python 3 and everything else is fine in Ubuntu 12, then definitely try to install it and that's it.
