8M5T-19C112 Language

[sanndo]

Did anyone find a way to flash sprm with another language?
Direct vbf upload or somethin?
I have Italy speech module and try to flash it with A...

[Go4IT]

I think your topic-title is a bit misleading. Your module is a Bluetooth-Module and the "well known" partnumber of it is 8M5T-19C112. You want to change this...

[sanndo]

Yep, done

[DGAlexandru]

It should also be in a different section, as this module is not BlauPunkt / Bosch

I played with language swap for this modules, first by modifying the VBF file - Eng language to look like the current loaded language but with no success - it fails at loading the FW.

Also writing / swapping all 3 flash memory chips doesn't change the Part Number of the module, even if the language swap is a success, at a future update from USB it will load the original language files.

[sanndo]

That was I think to do.. swap/reprogram eeprom inside.. but when you do this without success.. I think we need to find a way to do this language change

[Go4IT]

I think we need to disassemble the FW to get know how it work.

The Firmware resides in 3 Flash Chips (2, 7, 5) and an EEPROM (23)

Also, if you can read (translate) German, you may want to read my findings here: https://www.mikrocontroller.net/topic/475276

DGAlexandru: did you resolder the Flash chips? Or did you find a way to JTAG/BDM it?

[DGAlexandru]

Desolder, put in TSOP48 adapter, read and write, then solder back.
The chip that contains language is TSOP56... very hard to find & expensive.. so for this one I did a swap from a broken module.

I never played with that 25C64 EEPROM.. if here is the "language setting" I'm going to kill myself

[sanndo]

DGAlexandru if you have pcb on your desk, check this eeprom.. Or I can remove my from car and read and post dump here....

[sanndo]

Go4IT just downlaod your dumps and check it.. There is a strange data inside 95640:

WF0GXXGBBGBM18977
8M5T-14D511-BT
8M5T-14D512-AA
8M5T-14D509-AS
8M5T-19C112-BT
8M5T-19C112-BT

A here mean English, B - German... And why VIN is inside this dump

[DGAlexandru]

@sanndo

read your EEPROM and put dump here.
If you have:
8M5T-14D511-E*
8M5T-14D512-AA - this is common on all languages
8M5T-14D509-AS - this is common on all languages
8M5T-19C112-E*
8M5T-19C112-E*

Then modify them to be "-AN"
Put EEPROM back and read with ELMconfig the info from module.
If something now is with AN then try the update with 8M5T-14D511-AT.vbf file only on USB.

I don't have my soldering station at home.. I had to play with it at a client and I've left it in my car
