Title: Problems with Debian on A13-Wifi
Post by: reubeo on November 23, 2012, 08:11:04 PM
Hi,

I am able to boot the A13 with Debian and WiFi working, but have two issues, which i've had no luck resolving.

# uname -a
Linux debian 3.4.12+ #5 PREEMPT Wed Nov 21 23:52:19 GMT 2012 armv7l GNU/Linux

1) I can't halt or reboot the device, using either command results in the following error being repeated indefinitely on the console. 

[15578.560000] >>> no handle, treat it handle over
<3>>>> no handle, treat it handle over
[15578.560000] >>> no handle, treat it handle over
<3>>>> no handle, treat it handle over
[15578.560000] >>> no handle, treat it handle over
<3>>>> no handle, treat it handle over
[15578.560000] >>> no handle, treat it handle over

2) Duplicated messages on the console

Following the section below of the boot sequence all messages are duplicated on the console, alternating between the [x.xxxx] prefix and then <y> prefix. Any idea why?

[    0.440000] [uart]: used uart info.: 0x02
[    0.450000] sunxi-uart.1: ttyS0 at MMIO 0x1c28400 (irq = 2) is a U6_16550A
<6>console [ttyS0] enabled
[    0.470000] console [ttyS0] enabled

[    0.480000] [uart]: serial probe 1, membase   (null) irq 2 mapbase 0x01c28400
<6>brd: module loaded

Kind Regards, Reuben

I have exactly the same problem.

I'm using A13-Wifi through USB/FTDI connected to UEXT.
When I try to shutdown "shutdown -h now" :
" >>> no handle, treat it handle over" messages are spamming the console.

I use Putty on Windows through 115200 baud connection.

Anyone can help us ?

I can't even get a console.  I tried UEXT and now I just tried soldering on 4 wires to the UART1 to a breadboard to try to get a putty console. I installed the drivers numerous times but putty can't connect to any com port 1 through 5.  any ideas?

Not sure if there's been any progress on this front, but I'm guessing you followed instructions listed here?:

http://blog.klava.se/post/debian-sd-card-for-olinuxino-a13

I was able to reboot on the image provided by olimex, but cannot reboot on those instructions - of course, running debian seems to be much more stable on Anton's image than on the provided one. Rebooting is kind of a show stopper, though.
