Andreas
Under no circumstances I can make the LCD backlight flashing.
When I push BandM and Power button LCD backlight goes On and remains ON.
When I release BandM button LCD remains ON.
When I release Power button LCD backlight goes OFF.
Sorry you misunderstood, Peter has STM32F427VGT6 (1 MB), is working OK.
I have STM32F427VIT6 (2MB) and cannot have it loaded the bootloader as it seems..
Please be aware, that :
1) DFUdemo comunicates very well with my processor, it gives me correct info abt it.
2) DFU demo tells me that the bootloader has been uploaded correctly.
3) DFU demo tells me that it verifies the bootloader to be correct.
I just found that:
PB2 has a 4k7 pull-up resistor on the pcb, so that is why I do measure the 3.3V OK there.
PB0 does not have such resistor, so it shall have to be pulled up by the bootloader indeed, but I do not measure the 3.3V.
Should the MCU work properly (loading bootloader and firmware) when I just take the UI board seperately from the RF board and feed is by just the 5V_UI ?
That would make fault tracing more easy.

"Yes that works."
Oh, good, that makes it less complicated.
"Do you have another mcHF builder in your surrounding so that you can try flashing with a "known-working" OS software condition?"
Sorry, as far as I know I don't have.
OK, will continue tomorrow, can't be too difficult if it realy is a hardware problem.

What do you mean by that, my PC's OS software condition is out of the question.

@ Peter
OK Peter, great, I can speak a little German also, I learned it at school, but that is long long ago.
Reading it is OK, but writing a bit more difficult 
Speak to you later, maybe by the mcHF when it's working.

Hello Peter,
You say you have no problem in loading the bootloader and firmware in mcHF using Windows 10 64 bit.
As you know I have problems here.
Could you please check for me in the Device Manager of Windows, under USB Controllers/STM Device in DFU Mode/Properties//Events, if you have the errormessage there "Device could not be migrated" or not.
Although the Device Manager also says "This Device is working correctly", I have this message there and this could be the cause of my problem.
My STM driver here is "STTub30.sys V3.0B and it is certified by Microsoft, when I click"Check for updates" it says "There is no better or newer driver".
Many thanks in advance,
73
Jos
