Hi my friends! Is any chance to get bootloader from STM32F407?. My MCU burned (also MOSFET, and CAN controller). I`d change that parts, but i have to flash MCU. Only what i got i just firmware. VCXFW Ford.bin VCXFW GM.bin unlock STM32.pdf

Thanks a lot, but this connection working 100% on the older PCB. Best regards!!!

I got new BT module hc-05. Programmed OK. Now i see in BT network autocom from module, but i have problem to connect hc05 to board. I got older GREEN pcb like someone showed in that topic. Is little bit different than blue one. Thank you!

I connected to CDP, but do not work. I don`t see module in bluetooth network.

I did like this. Stop processor-dump orginal firmware (by tha way i can`t uploaded again) - flash erase - erase full chip- choose file -download.

If chip is erased then i got: i can`t download your file: 16MHz.rar

Thank`s a lot but the same error I made full erase chip.

I programmed with this firmware: Autocom bluetooth.rar Now when i`m running PSTool i got message : I got 16Mhz quartz. Maybe that dump autocom.rar is fake or something. i did all like here: https://www.instructables.com/id/Upgrade-Your-3-Bluetooth-Module-to-Have-HID-Firmwa/

It`s not the same PCB. Look at this pictures: I hope my connection is ok, but i did not change firmware in hc-05. I`m trying: https://www.youtube.com/watch?v=y8PcNbAA6AQ

I got exactly the same board like on this picture. Can You help me how to connect HC-05 ( HC-06)?. Thanks a lot, and best regards! I made connection like on the picture, but is not working
