Wanted: Bordbook removal script for MMI 3G HN+

[StanNB]

Hey experts,

since i have no skills in writing a sh-script for the MMI 3G, i try my luck here.
I have installed a modified bordbook on my MMI and I want to delete those files from the internal disk.
The bordbook installs the following files and folders that needs to be deleted:

source: metainfo2.txt

Destinations:

/mnt/gracenode/boardbook/boardbook_cs_CZ.iso
/mnt/gracenode/boardbook/boardbook_de_DE.iso
/mnt/gracenode/boardbook/boardbook_en_GB.iso
/mnt/gracenode/boardbook/boardbook_es_ES.iso
/mnt/gracenode/boardbook/boardbook_fr_FR.iso
/mnt/gracenode/boardbook/boardbook_it_IT.iso
/mnt/gracenode/boardbook/boardbook_nl_NL.iso
/mnt/gracenode/boardbook/boardbook_pl_PL.iso
/mnt/gracenode/boardbook/boardbook_pt_PT.iso
/mnt/gracenode/boardbook/boardbook_ru_RU.iso
/mnt/gracenode/boardbook/boardbook_sv_SE.iso
/mnt/gracenode/boardbook/boardbook_tr_TR.iso

Files to be deleted:

/mnt/gracenode/boardbook/browser.manifest
/mnt/gracenode/boardbook/boardbook.is?
/mnt/gracenode/boardbook/boardbook.is?.SWDL.compatibility.txt
/mnt/gracenode/boardbook/boardbook.is?.SWDL.version.txt

source: metainfo3.txt

Files to be deleted:

/net/mx/mnt/boardbook/update.txt
/net/mmx/mnt/boardbook/boardbook_cs_CZ.iso
/net/mmx/mnt/boardbook/boardbook_de_DE.iso
/net/mmx/mnt/boardbook/boardbook_en_GB.iso
/net/mmx/mnt/boardbook/boardbook_es_ES.iso
/net/mmx/mnt/boardbook/boardbook_fr_FR.iso
/net/mmx/mnt/boardbook/boardbook_it_IT.iso
/net/mmx/mnt/boardbook/boardbook_nl_NL.iso
/net/mmx/mnt/boardbook/boardbook_pl_PL.iso
/net/mmx/mnt/boardbook/boardbook_pt_PT.iso
/net/mmx/mnt/boardbook/boardbook_ru_RU.iso
/net/mmx/mnt/boardbook/boardbook_sv_SE.iso
/net/mmx/mnt/boardbook/boardbook_tr_TR.iso

The script should contain 3 screens: start, working and finish.
A log-file would be nice, too, with timestamp, error messages and list of existing files and/or folders to delete (if the files exists). And the script should not stop working if one fille is missing (in case of modiefied bordbook with only one language, like I did).

I hope that is not to complicated. Thank you !!

BTW: I placed an external hyperlink (h t t p s://...) to my modified bordbook-index-file, but the link won't open, there is no reaction. Can't the MMI internal browser open any hyperlinks to the www?

Greets !!

What is your goal here, to remove BORDBOOK completely from the MMI3GP system, or only certain components ? The Harmon-Becker software installation process writes files to persistent flash memory (/mnt/efs-persist/SWDL) and the HDD in /mnt/gracenode/boardbook.

Remove boardbook files stored on the HDD using an SD script with:

...
mount -uw /mnt/gracenode
ls -o /mnt/gracenode/boardbook/
rm -v /mnt/gracenode/boardbook/browser_manifest
rm -v /mnt/gracenode/boardbook/browser.manifest.SWDL.compatibility.txt
rm -v /mnt/gracenode/boardbook/browser.manifest.SWDL.version.txt
rm -v /mnt/gracenode/boardbook/boardbook.iso
rm -v /mnt/gracenode/boardbook/boardbook.iso.SWDL.compatibility.txt
rm -v /mnt/gracenode/boardbook/boardbook.iso.SWDL.version.txt
ls -o /mnt/gracenode/boardbook/
...

Regarding embedded external URLs in your custom boardbook, unless your MMI3GP has an active internet connection using the integrated 3G modem or an external LTE router (via a USB/Ethernet adapter), the embedded browser has no way to retreive HTML from the remote URL. Note that the Audi connect function for weather and other information uses the embedded browser to display information retreived from Audi back-end servers, so we know it should work, in theory. --g

I want to remove all boardbook files.

I started at first to log all installed files, but the script doesn't start after insert in the MMI. Pls don't laugh, I have no idea about sh scripts.
My first try that doesn't work:

#!/bin/ksh

# Script startup:
xversion=v241027
showScreen ${SDLIB}/mmi3g-0.png
touch ${SDPATH}/.started
xlogfile=${SDPATH}/run-$(getTime).log
exec > ${xlogfile} 2>&1
umask 022
echo "[INFO] Start: $(date); Timestamp: $(getTime); MU: $MUVER"

echo; echo "[INFO] MMI3G+ Bordbook remover: bordbookremover-$xversion"

# Exit the script if MMI3G is Basic
if [ "$MUVER" = MMI3GB ]
then
showScreen ${SDLIB}/mmi3g-bnav-e.png
  echo; echo "[INFO] Wrong MMI3G Model, MMI3G Basic is not suported for this script."
else
showScreen ${SDLIB}/mmi3g-1.png
mes=/mnt/gracenode
	mount -uw $mes
	# List installed bordbook files in Gracenode
	echo; echo "[INFO] ls ${mes}/boardbook/ ($(date)):"
	ls -o ${mes}/boardbook/

mep=/net/mmx/mnt
	mount -uw $mep
	# List installed bordbook files in net/mmx/mnt
	echo; echo "[INFO] ls ${mep}/boardbook/ ($(date)):"
	ls -o ${mep}/boardbook/
fi	

### Script cleanup ###
echo; echo "[INFO] End: $(date); Timestamp: $(getTime)"
showScreen ${SDLIB}/mmi3g-2.png
rm -f ${SDPATH}/.started
exit 0

The MMI is connected with the internal SIM-Card, AudiConnect is working, but the external link I created in the boardbook doesn't work.

I wish I would have the knowledge about that stuff you have.

Thanks for your help, Dr!!

@StanNB -- Your "run.sh" script looks OK to me. I assume that you have this on a FAT32 SD card that also has encrypted script copie_scr.sh in the root/top folder of the SD card and that your MMI3GP system is started fully (that is, all functions can be selected and operate correctly). When a properly configured FAT32 SD card is inserted into a running MMI3G system, a system process watches for insertion events and tries to identify the contents of the SD card. If the process finds encrypted file copie_scr.sh on the SD card, the process tries to decrypt the file to file /dev/shmem/copie_scr.sh as plain-text, and tries to launch the script as a new process. Our version of copie_scr.sh sets up the shell environment and "execs" plain-text shell script run.sh in the root directory of the SD card. But sometimes (not often) the SD card insertion event does not get processed correctly, so if the initial screen doesn't appear in, say, 10 seconds, you should eject the SD card, wait about 10 seconds, then re-insert.

In your case, you should find a (new) plain-text log file in the SD card root directly for every successful insertion event.

Note also that files in /net/mmx refer to next generation MIB systems; Harman-Becker MMI3G does not use file system /net/mmx. --g

[StanNB]

OK I'll re-format the SD and use your copie_scr.sh from Github.

Is the VIN stored on the HDD, too to echo it on a log?

I also want to log the version (part) number of the boardbook what is stored in the AudiUpdate.txt on "/mnt/gracenode/boardbook/", looks like: "version.default=161.565.8F0.99".
But I have no plan with find and replace. Simular to your code it could be something like this (just an idea):

### Get installed Boardbook Version ###
AUDUPD=/mnt/gracenode/boardbook/AudiUpdate.txt
if [ -e "$AUDUPD" ]
then
  BBPN="$(sed -n 's/^version.default=//p' $AUDUPD | sed 's/
$//')"
  echo; echo "[INFO] Boardbook Version number: $BBPN"

Thanks again!

[DrGER]

@StanNB -- You can use the copie_scr.sh file from any of my GitHub SD ZIP archives for your Bordbook remover script.

Regarding the VIN, I haven't seen this made visible easily anywhere in the QNX user space. The big Java/j9 process that implements the MMI3G user interface can access it through the MMI3GApplication process, but we don't have any means of finding this information from a shell script. If you try to retreive nav destinations from a connected myAudi account, you'll see that a Java debugging message is sent to the QNX syslog with the VIN:

00:02:44 LC62DBUG:MyAudiConnector: set VIN "WAUHFAFL4EN0xxxx8"
00:02:44 LC62DBUG:MyAudiConnector: set IMSI "232106908113543"
00:02:44 LC62DBUG:MyAudiConnector: set pairing code "8xxxxxx6"
...
00:02:45 LC62DBUG:LeanSoapTransport: Performing login with IMSI: 232106908113543 VIN: WAUHFAFL4EN0xxxx8

I tried some simple approaches using compiled Java code to access the VIN, but these returned only NULL strings, and then we sold the car soon after.

When you use sed to extract version text strings from configuration files like AudiUpdate.txt, you should know whether the lines of the file are terminated with the DOS-style '^M' character, which is what the second sed does in the example you offered, above. If the file does not contain any '^M' characters, the extra sed is harmless (but is not strictly necessary). Still, you have the correct idea here.

BTW, thinking about your external URL reference, the embedded UI browser (written in Java) has no concept of public HTTPS certificate files, so secure HTTP connections are likely to fail. The connections to myAudi destinations uses an embedded certificate for connections to Audi back-end servers. --g

Ok, i did. I use your showScreen and your folders, too, but the script won't start. I changed some code in the run.sh and tried another SD, but nothing. Your other stuff runs like a charm, but mine dont like to work. Thats really frustrating.
Could you pls have a look to the run.sh?

#!/bin/ksh

  then

Thanks for your explanations. I think we can forget the VIN.

When you use sed to extract version text strings from configuration files like AudiUpdate.txt, you should know whether the lines of the file are terminated with the DOS-style '^M' character, which is what the second sed does in the example you offered, above.

I dont really know that, but If the script maybe like to work some day I'll check the echo and see what happens.

BTW, thinking about your external URL reference, the embedded UI browser (written in Java) has no concept of public HTTPS certificate files, so secure HTTP connections are likely to fail.

Good to know. Another part we can forget, but its no pronlem.

@StanNB -- Mis-matched quote characters " or ' can cause shell scripts to fail, so be extra careful with those.

Are you using a Unix-friendly plain-text editor for your (new) run.sh file ?

My quick reading of your proposed shell script does not find any obvious problem that should cause the script to not run.

I suggest that you try to run this SD script in SD slot 2; wait at least 10 seconds after inserting the SD card before ejecting it again. Then, wait another 10 seconds and repeat the insertion to slot 2.
After ejecting the SD card with your run.sh script, run my MMI3G Info reporting script using a second SD card inserted into slot SD 2. When it completes, inspect the log file for SD insertion events recorded in the syslog (last part of the log file); do you find evidence that proc_scriptlauncher tried to process either of the earlier insertions, for example:

[StanNB]

Are you using a Unix-friendly plain-text editor for your (new) run.sh file ?

Yes, I use notepad++ for html and php, its my favourite tool for one of my hobbys, building websites. And its usefull for sh, too.

When it completes, inspect the log file for SD insertion events recorded in the syslog (last part of the log file); do you find evidence that proc_scriptlauncher tried to process either of the earlier insertions

I didn't knew that this procedure is possible. Great. I'll give it a try.


BTW: what's the difference between:

echo; echo "[INFO] info goes here.."

and

echo "[INFO] another info.."

??


EDIT 2:

It's working now! That's great.

Just the sed-part won't give me anything. The AudiUpdate.txt is a plain text file. I need the info from 'version.default=', in my case i need to echo: '161.565.8F0.99'. It's line 4 here, but sed should look for 'version.default=' since it can be another line, too.

The file:

device=boardbook
name.default=boardbook
name.de_DE=Bordbuch
version.default=161.565.8F0.99

My code dosn't work.

AUDUPD=/mnt/gracenode/boardbook/AudiUpdate.txt
if [ -e "$AUDUPD" ]
	then
	BBPN="$(sed -n 's/^version.default= //p' $AUDUPD | sed 's/".*$//')"

I think sed is to much for me.

[DrGER]

@StanNB -- It's good that you got your SD script to run properly.

The first part of your code to report the Boardbook version number is actually correct, it's the second sed that is the problem, since the AudiUpdate.txt file does not use a double-quote character to delimit the version string -- but the file DOES have MS-DOS style CTRL-M ^M characters as end-of-line markers, so you will need to remove the ^M character, thus:

...
BBVN="$(sed -n 's/^version.default= //p' $AUDUPD | sed 's/^M$//')"
...

where "^M" is the character CTRL-M embedded in the plain-text script.

BTW, I have the separate Boardbook CD for the B8 A4 published in 2011, and the plain-text AudiUpdate.txt file has only one entry for "version.default" in the form of:

version.default=version 132.565.8K0.88^M

Notice that the version string also includes the word "version" and the trailing ^M character at the end of the line.

Also: echo by itself in a script simply adds a blank line to the log file: echo; echo "[INFO] ...". The escape character '\n' (newline) probably works correctly with the QNX ksh, so you might give it a try: echo "\n[INFO] ..."

And this: if you're going to spend any time with QNX, you might find this reference useful: https://openqnx.com/static/neutrino/bookset.html

Hope that helps. --g

[StanNB]

but the file DOES have MS-DOS style CTRL-M ^M characters as end-of-line markers, so you will need to remove the ^M character

Great, thank you!!

Notice that the version string also includes the word "version" and the trailing ^M character at the end of the line.

That's interesting. My version from 2015 has no word "version" after the "=" in the plain text file. Seems that they changed something.

echo by itself in a script simply adds a blank line to the log file: echo; echo "[INFO] ...". The escape character '\n' (newline) probably works correctly with the QNX ksh, so you might give it a try: echo "\n[INFO] ..."

Nice. I've learned a lot from you. That's awesome. Thank you!!

Last thing: I tried to deal with "find" and "wc" in the script, bit run.sh can't find the binaries. I searched the web to download them, but can't find it.
Are they stored in linux anywhwew? I have an old pc with linux running.

Thanks !!

[DrGER]

@StanNB -- Re QNX binaries for find & wc, you won't find them on any Harman-Becker MMI3G systems, as they are not needed generally for the MMI3G run-time environment. Look at /mnt/ifs-root/bin, /mnt/ifs-root/usr/bin, /mnt/ifs-root/sbin, /mnt/ifs-root/usr/sbin, /mnt/efs-system/bin, /mnt-efs-system/usr/bin, /mnt/efs-system/sbin, and /mnt/efs-system/usr/sbin for QNX run-time binaries. These are all compiled for the MMI3G CPU, a 32-bit RISC processor made by Renesas. Binaries from other operating systems (Linux, Unix) and CPU architectures (x64, ARM) will not run on the MMI3G QNX 6.3.2 system. Fortunately, we can do quite a bit with the shell, grep, sed, and a few others. It's even possible to run compiled Java programs using the installed run-time environment (in /mnt/ifs-root/j9/bin). --g

[StanNB]

@DrGEr,
Thanks to your help, I'm almost there. However, I now have another problem. The system is Read-Only, I can't change or delete files. I tried 'chmod-r 0777', 'mount -uw', 'remount' and some other stuff, but nothing helps. Did I crashed the system now?

EDIT: Would your HDD-MJan-Tool fix the permissions?

Greets!!
