Re: cdc-acm module for 2.6 kernel

Hi,

May I ask about the best gpm settings for the Letux 400?

/dev/mouse
autops2?
ms3 to repeat events?
Rest of options blank?

David

Hi, Wolfgang.
  This really helps! Actually from now the mipsbook really became useful
  for me.
Thanks,
  Dima.

P.S.
  on my system it goes from 0 to 100 instead of 0-10.

Re: Querying battery charge level on Letux 400

Hi Dima,
somehow it should work using the components from 3MX distribution.
I tried a little but could get it running due to less time .
Currently i use the value in /proc file system to get battery status:
cat /proc/jz/battery-level
=> the value provided reflects the battery status.
     a value > 220 is a full battery
     a value < 200 battery is getting empty.

hope this helps a little

Regarding ScreenBrightness:
as far as i know this can't be set on the console since its a fixed time 
period set in the kernel.
This means after some period of inactivity the screen is switched off - 
of course your letux is still running ;-)

Here it help a lot.

Ok, intervals can't be set.

Do you know how to control the screen brighness directly ?
The screen on Letux400 is too bright for me often.
For me it is a health of my eyes :) , not a power-mgmt option...

Letux 400 power saving control

Dima — 2012-09-18T11:57:42

Hi.
  Working on a Debian Lenny (2.6.24.3 kernel), on a pure console (no X)
I see that after some period of inactivity Letux considerably dims its
screen and then, after additional period, turns itself off ? It occurs
regardless of AC power presence.

  How are these time intervals set up (on battery and on AC power)?

Thanks,
  Dima.

Screen brightness on Letux400

Dima — 2012-09-18T11:42:04

Hi.
  I have a Letux400 with a Debian Lenny system (2.6.24.3 kernel).

How is screen brightness controlled in this system? (command line, X,
simple API -- all are good for me)

If this system does not support screen brightness control, does a later
kernel do?

Thanks,
  Dima.

Re: connect to ad-hoc network?

Matt Oudenhoven — 2012-03-19T05:27:06

I use ad-hoc on most my devices now because i just wireless tether to
my cell phone. This is the config i'm using on all my machines.
Haven't tried it on the mips netbook as its been sitting in a box for
awhile now, but i don't see why it wouldn't work on it.

ctrl_interface=DIR=/etc/wpa_supplicant GROUP=wifi
update_config=1
ap_scan=2
#AD-HOC NO AUTHENTICATION
network={
   ssid="YourSSID"
   scan_ssid=1

Hi ,
i am trying to connect to an ad-hoc network using my little letux400.
i tried different wpa-configs but none of them did work.
is there someone who got it working?

Hi,

 
1) I am using my old school debian lenny setup on trendtac epc700:
link to download here: http://lists.linuxtogo.org/pipermail/mipsbook-devel/2011-October/000374.html

 

2) other option is to build your own distro from scratch using a bootstrapped debian mipsel version. 
Nikolaus collected several ones here together with install instructions:
http://download.goldelico.com/letux-400/
 

First step is to get wifi working as wired lan is NOK for 2.6.31.3.
debian lenny libs needed: udev wpa_supplicant lsusb zd1211-firmware
check dmesg for correct loading of zd1211rw firmware to cardname (can be wlan0 or eth1) 
wpa_passphrase your_ssid your_psk

And fill in at /etc/wpa_supplicant/wpa_supplicant.conf
add/update your wireless  settings in /etc/network/interfaces
#ifconfig wlan0 up
#wireless-lan
  wlan settings: dhcp auto dns
  connect
 
3) 3mx ultra for 2.6.24.3 will run, but wifi is not working on this distro with external zd1211 usbstick, 
I get couldn't load zd1211 firmware, glibc / udev / lsusb compa

Re: Trying to get a working kernel installed on device

Ruben Viets — 2011-09-18T19:07:22

Hi,
 
No problem.
 
1) Lenny's size is much more as distro's like 3MX, this will be a size(>1GB) issue when you start to install more applications on lenny.
Next to that nand yaffs2 ecc is not ok for these kernels, this can cause loss of data (especially when the number of bad nandblocks are increased).
Therefore I would advice to use SD card instead of nand.
 
If you don't bother about these issues you can use these kernels to boot from nand too. At own risk.
 
2) The kernels include cifs support, maybe udev & samba support is not correctly installed in your lenny distro. 
#apt-get install udev samba.
 
3) You can add the /dev/mtdblock1 and /dev/mtd1 you're self, don't need additional modules installed.
#cd /dev
#mknod mtd1 c 90 2
#mknod mtdblock1 b 31 1
#chmod 755 mtd1
#chmod 755 mtdblock1

Re: Trying to get a working kernel installed on device

Ruben Viets — 2011-09-18T12:09:38

Hi,
 
To install the 2.6.xx.x uImage to /dev/mtdblock1(nand), you cannot do that by press f1+fn+left shift, this will mess up because the /dev/mtd0 bootloader is not made for 2.6 kernels.

There are several way's to do/fix that
1) If you want kernel 2.6.xx.x to be installed on nand
    use an uImage 2.6.xx.x copy to fat16 sdcard partition 
    First try-out with fn+left shift if it boots ok. 
    Next is to copy uImage to the /dev/mtdblock1. Start an terminal and type cat uImage > /dev/mtdblock1
 
2) If you want to fix/restore older 2.4 kernels.
    Copy the existing 2.4 kernel (such as the one from elonex, skytone, alpha400) to fat16 sdcard partition.
    First try-out fn+left shift if it boots ok.
    Restart and Press f1+fn+left shift and this will copy the 2.4 uImage correctly to /dev/mtdblock1
 
3) For development/new package installations it is safer to boot a distro from SD card, especially if the size will be close to 1GB. 
    The 2.6.31.3RV kernel is not able to boot an distro from SD card, it can

Trying to get a working kernel installed on device

Maarten Stolte — 2011-09-18T06:28:53

Hi,

I have decided to try and make my Trendtac 700 into a small Linux mediaserver.
For some reason I also decided to try and get Lenny on to it at least,
but because I wanted to have it on the device instead of on a sd card,
I went this route:

1. install the rescue image from this url:
http://download.goldelico.com/letux-400/etch/Recovery_DebianEtchX11v4.img
2. I then started dist upgrading that to Lenny, to discover that Lenny
needs a 2.6 kernel (ofcourse)
3. Then I downloaded the latest kernel
(http://projects.kwaak.net/twiki/pub/Epc700/KernelPort26Compiling/uImage2.6.31.3RV112),
and put it on a sd card.
4. As this booted my Lenny just fine, I decided to try and install the
kernel for real, pressing f1+fn+left shift during boot.

As you may have guessed, this let to a screen washing out in various
colours when attempting to boot normally now. Booting from SD card
still works fine.

Now my question is, how do I solve this if at all? Worst case, can I
somehow make the system boot from an SD card, or a usb

Hi,
 
You may need to insmod additional kernel drivers to support 3G.

The ones supported by ingenic kernel are ipw.ko(serial usb 3G UMTS TDD) and option.ko (serial usb GSM CDMA). 
I compiled them and put them here:

Hi,
 
I copied some part of your patch, which made ethernet work. I do not think it is related to your patch.
 
Probably related to previous quick 'fixes' made by me in patchminibookRV11.
