How do I recognize a MST2 Delphi Unit?

• Delphi Units are always standard devices (MST2) and not high (MHI2) devices.

• Accordingly, a Delphi unit is always a MIB2 Discover Media or MIB2 Composition Media and not a Discover Pro type unit.

• All Delphi Units are Discover Media or Composition Media devices. But not all Discover Media and Composition Media devices are Delphi Units! It can also be a Technisat/Preh unit.

• To recognize the unit without removal, it is necessary to hold down the MENU button on the radio for 3 seconds to open hidden service mode. In this menu go to Software Update/Versions and check SW Train.

  

• Delphi SW Train Version scheme example: MST2_EU_VW_P0891D.

Requirements - What do you need?

• Delphi MST2 unit,
• Diagnostic tool to enable Developer Mode (VCDS, VCP, OBD11…),
• Quality SD card (how to test SD card),
• Ethernet-USB adapter supported by the unit (D-Link DUB-E100 or alternative),
• Ethernet cable,
• Patch files from mibvault.com.

Network settings

Software-Version

Activate Developer mode and GEM

Activate the Green Engineering Menu (GEM) with VCDS, OBDEleven, VCP, or any other diagnostic interface.

Check: 5F - Enabling Developer Mode and Hidden Menu for more details.

Update FW

P9122D (MU0842) ➔ P0867D (MU0867) * ➔ P0890D (MU0890) ➔ P0891D (MU0891) ➔ P0876D (MU0876) * ➔ P0879D (MU0879) **

* = Telnet is not activated on this FW

**= there is a modified firmware (MST2_EU_VW_P0879D-wTelnet) on the mibvault.com server with telnet activated. Read in the folder oft this FW: patch\howto.txt !!!

Run FW update

1. Format SD card to FAT32.

2. Copy firmware update files to the SD card.

3. Insert the SD card into the SD card slot 1.

4. Remove all other SD cards and USB devices!

5. Press the MENU button on the radio longer until another (service) menu opens. Select the test mode there.

   

6. Switch to the "SWDL" category.

   

7. Activate Software Download Manual Download and tap "Start Download".

   

8. Select source (SD card), select everything and start firmware update.

   

Fix Software Version Management (SVM) error

Use VCDS / OBDEleven / VCP to clear the erroro from unit.

TELNET Connection

Enable ethernet

Hold down the MENU button on the radio until the Service menu appears.

Navigate to Testmode

Select Green Engineering Menu

(optionally you can also get there directly by pressing the MENU button for a very long time)

Change to the category "debugging mlp"

Check Ethernet box and restart the unit (hold down the power button for at least 10 seconds)

After the unit has been restarted enter same menu again and also check Switch to MLP must be checked. (Note: If only removing CP, it does not seem MLP needs to be selected 8/7/2023)

Connect with Putty - Telnet

Now the USB-LAN adapter can be connected to the USB port in the vehicle and connected to the laptop via LAN cable. If the LEDs othe adapter light up, if the cabling and network configuration on your PC/notebook are correct.

Putty can now be started.

The IP address is taken from the GEM menu debugging mlp.

IP 192.168.1.4  and port 23 are default on all units.

If everything has been configured correctly, you can tell from the QNX Neutrino login message that it worked.

Only the word root (NO password) is required as a login to Delphi units.

As soon as Welcome is shown, commands can be entered.

Patch unit

Common shell commands:

• cp = copy
• rm = delete
• chmod = change rights (e.B. chmod 777 = full read/write permissions)
• mkdir = create directory (folder)
• mount = mount path
• umount = unmount path
• && = execute another command

Attributes:

• -f = force (overwrite / force)
• -R = recursive (e.B. copy/delete folder including contents and subfolders)
• -t = mount request / special type (e.B followed by qnx6)
• -u = update (remount)
• -V = progress indicator
• -w = read/write permissions (when mounting)

Create backup - recommended

Insert empty the SD card into SD 1 port and execute the following commands via putty.

Enter the commands exactly!

Unintentionally set spaces can lead to bricking of the unit!

This note is especially relevant for users who use a translator because they partially insert unwanted spaces.

Manual input

   cd / && mount -uw /sdc1/

2. Create backup folders on the SD card

   mkdir /sdc1/backup/

SWaP (FEC) patch

However, an already patched FEC container can also be easily changed with your VCNR and FIN.

This *.fec  file and patched  SWaP  will be copied to SD card and insert it into slot 1 of the unit.

First, the patched SWaP file is copied to unit.

delphibin.ifs (CP) patch

1. Copy patched delphibin.ifs that corresponds to Train and unit type onto the root of SD card

2. Insert SD card into SD 1 slot of the unit.

3. Create backup of the original delphibin.ifs: \n cp -Vfr /extbin/apps/bin/delphibin.ifs /sdc1/backup_delphibin.ifs

4. Copy patched delphibin.ifsto the head unit: \n cp -Vfr /sdc1/delphibin.ifs /extbin/apps/bin/delphibin.ifs

5. Sync file system:

   MountPathSync /extbin/apps

6. Restart the unit

   shutdown -S reboot
