Hi Andreas and Winfred,
Thanks for the replies
The bootloader I'm using is the one found under "Latest release version 1.2" and I guess it is bootloader version 2.0, a bit confusing is'nt it ?
Well there should be 3.3V over the opened Band- button as I supposed.
There isn't, so there is but one conclusion possible : The new processor doesn't pull-up PB0, which is vy strange for a brand new one.
Luckyly I ordered 2 of them, I will exchange it and hope for the best (hope the PCB will withstand all that mistreatmnt).
Best 73

Hi Andreas,
I exchanged the processor (STM32F427VIT6) this morning and you feel it coming : Makes no difference !
Installing the bootloader went flawlessly: "Upload succesfull".
Jumper J6 has been removed.
When I press the power button, button Band+ goes high (3.3V), Button Band- remains low.
I checked the Band- button for a short, it is open.
I checked for continueaty from Band- button to PB0 (pin35) of the processor : trace is 0 Ohms
Conclusion : It has no sense to press Band- button for loadng the frmware, for it is low already.
Question: What makes PB0 go high, there is no firmware loaded yet.
Should it be high by default of the processor, is it done by the bootloader or what else?
That the problem is caused by processor failure now looks unbeleavable to me.
I'm confused, remember, all went well with a 32F407VGT6 and the same USB stick in the DFU USB connector. I am even thinking of going back to the old processor but I don't like to (another attack at the PCB).

OK, the bootloader.
I took the bootloader from the website under "Latest version 1.2.0" twice, correct ?
Any other ideas ?

If you mean with "website" Andreas' github site:
https://github.com/df8oe/mchf-github/releases
than you are perfectly fine under 1.2.0.
There its the bootloader.dfu Image.
After installation with Dfuse the mcHF shows a "Bootloader 2.0.0" in the power on screen.

@ Peter
Yes, that is the one, I am using that bootloader.dfu file from there.
@ Andreas
I will do some more tsting, maybe the old bootloader and the memorystick on the mini USB connector.
Will keep you informed.
Nice weather here, 30 degrees C, no good for HAM radio

By the way, my operating system on the PC is Windows 10 Pro 64 Bit.
I think to remember having read somewhere this is causing problems in flashing the bootloader ?

I have both tested it under OS-X Yosemite and also under Winblows 10, 64Bit.
There is no issue with Win 10 and Dfuse. It works out of the box and needs no drivers etc.
Let me add that my Win 10 is still the 1511 version and not the new 1607 "Anniversary Update".
