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

[mike1968]

What are you trying to connect to?

Not sure. Can you send me a (product) link to what you're trying to use?

R15 same probleme
I use a pl2303 usb to serial adapter.
With lsusb it is detected as bus 002 device 005, but there is no /dev/ttyUSBx

Going to require a new kernel. Building now and will upload in a bit. I'm trying to get by with generic drivers, rather than having to build about 400 modules, but if it doesn't work, we can go the other way too.

R16 kernels are up. Try them and see if they work for your USB->serial issues.

Jwischka thank you for the kernel.... but sorry...didn`t work

Still no   /dev/ttyUSBx
What did i wrong???

Best regards
Michael

It is a usb->seial adapterlike this:
http://www.exp-tech.de/Zubehoer/USB-SERIAL-CABLE-F.html
It works perfect with my raspberrypi
Best regards

Well, i have some modules with serial interfaces from my arduino-projekts like  gsm,gps,bt,rf,xbee

[jwischka]

Ok... now that I know more of what you're trying to do, I'll see what I can figure out.

My wife is having surgery tomorrow, so I'm not sure how quickly I'll get it done, but I'll try to keep you posted as to progress. Hopefully it's something simple.

[bimodh]

Does'nt it has a USBSerial Driver? Whenever I tried to connected the MOD-USB-RS232 module to the board, the device is not creating in the /dev. Why is it so?

[LubOlimex]

Hello bimodh,

The problem is probably in the MOD-USB-RS232. There is a high chance that the MOD-USB-RS232 you received was shipped without the final firmware it needs. The situation is further explained here: https://www.olimex.com/forum/index.php?topic=810.msg3644#msg3644

Sorry for the incontinence caused.

Best regards,
Lub/OLIMEX

Hello jwischka

Thank you for the work. I am a beginner in embedded linux. What you have done is a big help for me.

I have tried R15 and R12 video images on a A13 board. Both have some problems with a boot. There is only a flashing underscore symbol "_" on a VGA screen. Maybe the reason is that i don't have serial connection? Unfortunately i didn't ordered serial cable for this board. Do you have other suggestions what is the problem?

Fortunately linaro image from wiki works.

Modified 20.02.13
I made some experiments and found that this is not a problem of the image, but the problem of my zip utility.
It's very strange but if I extract image on windows it works but when I extract by unzip or ark it doesn't.
I checked that md5sum of downloaded files in linux and windows are similar.
I use openSuse 12.2. Unzip version 6.0

[jwischka]

I'll look into it, but video output should be enabled. I'll have to connect it up to a monitor, which I can probably do this afternoon.

It's possible it might be a script.bin issue?

The procedure (diagnostic) went well, but results were not very good - looks like open heart surgery this summer.

I'll try to look at it this afternoon, but I haven't had a chance yet.

I had a heard attack last summer..so i can believe you feel

Mike -

New kernels should take care of your problem:

R17 headless
R17 video

Get current version (R17) here.

Hello jeff,
My problem solved.....usb serial is running.
Thank you very much

Hello;

By way of report, I haven't had any luck yet with R17, R15, R12 on my board.

After numerous iterations, the most promising outcome has been that my OLinuXino enters a sort of boot-loop, where the screen fades in grey then goes black again every 15s, sometimes with a fine line about 1/3 of the way down the LCD.

The board's a rev.c WIFI with the 7" LCD and touchscreen, as well as the Olimex-supplied AC adapter. It's been flashed with the LCD image to internal NVRAM.

I've tried a limited variety of sizes and brands of uSD card (Adata 16GB, Kingston 4GB, Phillips 4GB). DD actually returns an out-of-room error when I try flashing the images to either 4GB card. I've tried both 'sudo dd if=yourfile.img of=/dev/sdX' as well as 'sudo dd bs=4M oflag=sync if=yourfile.img of=/dev/sdX' (where X is the letter representing the flash card in question). I 'Eject This Card Safely' from Nautilus each time as well postflash.

The board boots Android ok. I also have tried an Olimex-supplied Debian uSD card. That just boots into Android with a message about a damaged SD card. So I'm out of ideas.

Any tips? Sorry to bug jwischka and other contributors - without you, we neophytes wouldn't have an in, so thanks.

[jwischka]

It sounds like there's some sort of kernel panic happening, perhaps. Is there any chance you have a usb-serial adapter and could get a log of the messages? It's going to be really hard to debug what's going on without that (unless I actually figure out a way to redirect it to the VGA, which is on the eventual to-do list).

Probably best to use an SD card with enough room.

We keep posting the same information: many "4GB" cards are LESS than 4GB so the image does not fit.

Easy fix: use a bigger one.

If dd fails, not much point booting the card.
If dd is OK, try booting.  If that fails, look at the debug messages on uart1
Easy to record them using e.g.
screen -L /dev/ttyUSB0 115200

Hello all,

I also have the problem with the 4GB uSD.
Hope this helps shed some light into the problem.
After flashing the image, dd reports: no space left on device (3.9 GB copied).
About the reboot cycle. It's due to a kernel panic, indeed. There is a problem related to mounting the file system.
This is what is reported thru the serial-usb connection:
