The bootloader: 1. Download the software Flash Loader Demonstrator and install it.

2. Burn the Bootloader via Flash Load Demonstrator.
2.1Access the 12V or 24V voltage for the GTM32 Pro VB motherboard (according to the model to select the appropriate voltage)
2.2 Insert one corresponding jumper cap on the boot0 of the board.
2.3 Connect the USB cable.
    2.4 Press the RESET button.     2.5 Open the Flash Loader Demo, confirm the COM port, for the rest do the setting as default. Click the Next. 2.6 Choose the bootloader you want to burn and check the "Global Erase" radio and the address "8000000" and click Next to install it.     2.7 It means the burning is successful if you see the words of "download operation finished successfully!".    

Great instruction.
Everything works perfectly..

Hey,
First I've made a mistake : i've burned the firmware at te wrong adress 8000000, overriding the boatloader.

Today I've burned the boat loader as discribe (global erase, at 8000000), and after I've burned the firmware as well (erase necessary pages, at 8002000) with the correct options.
But it doesn't work, always the 2 blank lines on the screen of my Rostock301.

NB : I've put the jumper first and powered the STM32 after, and then reset it with the tiny button - is-it the correct order ?
Do you have an idea ?
Thanks for your answers

You can control the printer through the USB port and then determine whether the mainboard is working
(Then you can ensure the issue root is LCD or not)

Hey William,
It works well, I've pluged the jumper after power on ! I've burned the bootloader and after I've burned successfully the 1.0.02 firmware.
...but with the same process I've tried to burn the 1.0.03 version but it doesn't work. Is the process the same for this version ?
Regards
Stéphan

When the STM32 Pro VB controller board is ready to load programming, an additional LED lights up (somewhere near the jumper).
Then you can be sure that you can load the firmware.

bonjour

j'ai une M301 mais qui ne fonctionne pas et j'aimerais savoir quelle est le dernier firmware a utiliser 1,0,3 fichier bin ou 1,0,5 fichier hex

merci

The mainboard type of Rostock 301 is GTM32 PRO VB

Hello.
I also had the same symptoms.
I installed firmware (gtm32 machine delta.bin) to change to 270 ° C specification and it did not work properly.

I installed Rostock301V1.0.0.3.bin and returned to the original. However it can not be changed to 270 ℃ specification.
TPU filament can not be used because the temperature is low.

You need to re-burn bootloader also
