[IMAGE] A13(-WIFI) Debian (now Ubuntu) + xfce flashable (Updated: 08 Mar: R18)

[SlyCom]

I don't know if the camera is UVC but what about the bluetooth usb dongle?

[drspastic]

hi, hows things? i have been away from the forum a few months. i am still using 3.4.29-jwischka-3.4-video-20130209-R15+ and its been great so far. i did just get a Realtek RTL2832U based dongle and dmesg didnt pick it up other than a usb device. is there a shortcut way to get this working without a recompile?

Probably need a new kernel. I'll see if I can get the new 3.4 branch to be a bit more stable and look into a release...

hm... dmesg does see it now

and the led comes on so its not so bad after all.
just need the module.

by the way, these dongles have 2 uses, requiring different modules that i hear can clash:
first is the dvb-t / dab standard function, second is rtl-sdr taking raw sample stream for
software defined radio like gnuradio etc. 24-1850 mhz can be had from the rtl2832/r820t dongles.
i read that the r820t tuner chip can also be software disabled somehow to allow raw samples from dc-24 mhz to be decoded too.

anyway, im rambling..... just thought it might be interesting as it opens up a big chunk of cheap connectivity

Why sometimes the board boot correct but sometimes it try to boot from nand? Is it a SD card issue?

I'm not sure to be honest, though I can tell you I experience the same behavior.

[SlyCom]

So is there any solution for this issue? My device works remotely and in case off power cut it sometimes not starting.
Is there any solution to write the image to NAND?

P.S.
What is the user and password for version R19 ?? I can not log in using olinuxino/olinuxino.

I'm the only one who can run this image of Debian un the A13MICRO board ?!

ubuntu/olinuxino

I haven't spent a lot of time looking into the boot issues - writing to NAND would likely be a workable solution, though I haven't looked into doing that either. I know that others have looked at booting from NAND, but I haven't kept up with that line of posts recently.

Hello

I'm wondering why I can't get the image to fit on any 4gb card, with Linux or Image Writer or Roadkils image writer on windows

for example:

jonne@Ibuntu:~/Downloads$ sudo dd if=~/Downloads/olinuxino_xfce-r18.img of=/dev/sdb
dd: writing to `/dev/sdb': No space left on device
7626753+0 records in
7626752+0 records out
3904897024 bytes (3.9 GB) copied, 1975.27 s, 2.0 MB/s

... running out of space with something like 1 or 2 sectors to go

Obviously, the solution is to buy a 8 or 16 gb card to write the 4gb image. i just dont understand why the image is 3.7 GB when all my 4GB cards seem to be 3.68 in capacity.

i wonder if this is related to:

[jwischka]

What brand of card are you using? The image is made from a legit, 4GB Sandisk card. Cards with bad sectors (or fewer sectors) will obviously experience problems. I've used WinDiskImager and dd to successfully write the images to other (Sandisk) cards, however.

I suppose I could try to pull an image with DD, if you would like me to try, but I suspect it's a physical card problem, not a software issue.

wow. Fast reply. Thanks.

No need to bother with pulling a different image with dd. All my cards are Kingston... I've suspected them for a while. Your 4 gb sd images are not the only ones I cant get to fit.

That's good information to have. I may try to grab a Kingston card in the future, then, for making images. Obviously you can put a smaller image on a larger card, so having the "smallest" 4GB card possible would be good - from the perspective of the image maker.

Hi jwischka,

Your ubuntu distribution is brilliant. I wonder if the destribution will work with Olinuxino iMX233-Olinuxino board?

With the right kernel, probably, though it would be quite slow, I suspect.

Hi,

I'm going to use devices connected to Olinuxino A13 via UART (Ubuntu r18). I'm using USB to UART dongle. The question is: Is there any option to use internal uart port? I read somewhere that there is UART but it's connected to sd card.

[David Goadby]

If you need actual RS232 signal levels then an easy solution is to use an EXT module MOD-RS232. At €5.95 it's not worth getting the soldering irion out.

Alternatively, if TTL is ok then 3.3V serial is available for UART1 and UART0 on the appropriately named connectors.
