It means that the function of pin 12 is unknown. You shouldn't connect anything to it. A standard null modem is a three-wire connection, GND, TxD and RxD, so connecting these should suffice.

Ok that very clear to me but where does the 3.3V fit in this story

Code: Select all

serial port (3.3V logic levels, ttymxc0, 115200 baud, 8N1):

Toon is a 3.3V device. 5V connections are likely to fry the hardware.

@gielie,

i assume you're using some kind of USB to TTL device (as described in the rooting manual) Or maybe and ESP8266
If that's the case you don't need the 3.3v connection. Just connect the three wires as described.
Check your comport (device management> ports) look for serial port and write down the "number" (E.g Com1 or Com3 or Com5, you get the idea)
Fire up Putty (or other preferred terminal client) with the described settings and boot Toon. (Settings: ComX (Where X is the "number") 115200 baud, 8N1):
If you see readable data then you're ok. If you see nothing or gibberish (unreadable) check your connections and settings.

@marcelr @Ierlandfan

Thanks for the help.
Yes I have a usb to TTL but my W10 laptop doesn’t recognize the cable, try to figure this out this weekend.
I already opened up my Tonn and it looks simple, I have good experience with putty so if the usb cable works I will manage.

I’ll report back when it’s done.

Many of those usb to TTL-cables are cheap chinese versions with a copied Prolific pl2303 chip. Recent drivers (from Microsoft auto update) block these variants. To make use of them you have to search for the older ones. Exact version depends, good luck.

That's why I recommend the FTDI-based interfaces. If you want to use the prolific chipset-based stuff, download the drivers directly from prolific, and you may get your stuff to work, although it's still a challenge. The drivers that are shipped with windows (who needs that OS anyway?) are notoriously crippled.

True, I bought one for 1 euro, I measured the v and this was just right.
Today I rooted my Toon with succes, the Toon App Store is already running.

Thank to all the guys who made this possible.

Hi all,

Got myself a nice Toon (2nd hand), and updated it to the latest version 4.9.23 with the official Toon software.

Then I followed the guide on domoticaforum.eu/viewtopic.php?f=87& ... mp;t=11235 and found U-Boot 2010.09-R6 (Mar 14 2012 - 11:15:10) in my Toon. That was an easy entrance

After modifying inittab and passwd I resetted the device, expecting a shell, but all I see is this:

Code: Select all

HCBv2 apps started via runlevels, performing 'addstartables && reload && init 5 or 5'.
HCBv2 adding: comm eventmgr kpi pwrusage scsync smartplug thermstat usermsg weather bxtproxy config log rrd watchdog hue p1 zwave lighttpd.
HCBv2 startables unchanged, not writing /etc/inittab.
getty: applet not found
getty: applet not found
getty: applet not found
getty: applet not found
getty: applet not found
getty: applet not found
getty: applet not found
INIT: Id "gett" respawning too fast: disabled for 5 minutes

The message "eneco-001-xxxxxx login:" never appears.

Going back again to U-boot and dropping to /bin/sh and trying manually results in:

Code: Select all

/sbin/getty -L 115200 ttymxc0 vt102
getty: applet not found

What is this 'applet' and why is it not found?
What is exactly going on here?

Posted: **Sat Nov 11, 2017 12:27 pm**

Let's check some basics:

Since you modified inittab and paswd so I assume you know how to reach single mode
Try

Code: Select all

ls -la /sbin |grep gett

on the commandline and see whether "getty" exist.
Should say:

Code: Select all

lrwxrwxrwx    1 root     root            14 Aug 29  2012 getty -> ../bin/busybox

If it exist it's probably some error in /etc/inittab/

The line in /etc/inittab looks like this

#Not default stuff
gett:235:respawn:/sbin/getty -L 115200 ttymxc0 vt102

Let's start from there.

Posted: **Sat Nov 11, 2017 9:41 pm**

I checked some basics and have some more information:

Code: Select all

/ # ls -la /sbin|grep gett
lrwxrwxrwx    1 root     root            14 Aug 29  2012 getty -> ../bin/busybox
/ #

The relevant line is in place:

Code: Select all

# HCBv2 static stuff
#ovpn:235:respawn:/usr/sbin/openvpn --config /etc/openvpn/vpn.conf --verb 0 >/dev/null 2>&1
qtqt:245:respawn:/usr/bin/startqt >/dev/null 2>&1
# add serial console access: (added, MR!):
gett:235:respawn:/sbin/getty -L 115200 ttymxc0 vt102

My complete /etc/inittab in a gist:
gist.github.com/Rubyan/dee691c6affbb213 ... le-inittab

Could it be that I updated to Toon software version 4.9.23 before rooting? This version is only 2 days old as can be read on the toon forum forum.toon.nl/software-updates-26/softw ... ie-4-9-871

Highly unlikely.

busybox hasn't changed since version 1.9.10 or thereabouts.

What happens when you try this:

Code: Select all

/bin/busybox getty -L 115200 ttymxc0 vt102

Posted: **Sun Nov 12, 2017 9:07 am**

What happens when you try this:
Code: Select all
/bin/busybox getty -L 115200 ttymxc0 vt102

The following happens:

Code: Select all

/ # /bin/busybox getty -L 115200 ttymxc0 vt102
getty: applet not found
/ #

Also without params

Code: Select all

/ # /bin/busybox getty
getty: applet not found

A simple command 'ls' just works:

Code: Select all

/ # /bin/busybox ls
HCBv2       configured  lib         proc        sbin        usr
bin         dev         linuxrc     qmf         sys         var
boot        etc         mnt         root        tmp
/ #

Some googling brought me to stackoverflow.com/questions/19043700/bu ... -not-found explaining how busybox works:

The way busybox work is it looks at it argv[0] parameter which is the name of the symlink; vim in your case. It then does a look-up and it has no applet named vim. You can make a script that does busybox vi and symlink that script to vim. The syntax busybox applet, is another way to select the program; but why not just type vi. An applet in busybox parlance is the emulated program. busybox has base infrastructure (command line parsing, etc) with a main driver file that is an applet emulating the normal program. –
Nice. I didn't know this. All the common programs are symlinks.

So is my busybox incomplete somehow? Lets see the details:

Code: Select all

/ # ls -liah /bin/busybox
 125032 -rwsr-xr-x    1 root     root      679.2K Oct  3 12:22 /bin/busybox

Hmm 3 oktober 12:22, what year? That would be this year, 5 weeks ago.

Some more googling shows you can list all busybox applets with the plain busybox command:

Code: Select all

Code: Select all

 uname -a

Every time I log in I get

Code: Select all

sh: xauth: not found

I simply ignore it

Posted: **Sun Nov 12, 2017 3:11 pm**

Hmmm ... apparently, in 4.9.23, busybox got updated.

and getty removed from the busybox features.
I just downloaded the latest busybox code, will try and build one with getty on board.

Will also take a look at the latest installation, see if a rollback can be done easily. (the first installation of busybox is built routinely in the oe-tree).
