Hi,

now we tried PD6 PA10 and PB5 at 0V, nothing happens.

Processor data is:

STM32F107

VCT6    Z

990MF    VC

MYS 99 961

ST e4 ARM

Hi,

Hint. have you tried with PD6 and PB5 in 0V ?

Question: What do you mean by ''PA10 connected via cable to 3,3v'' ? is it USB cable ? because PA9 is the VBUS pin not PA10.

More important:

''Processor date code=961'': date code = YXX where Y= year and XX=week (max is 52) (at least that's what they say in the product datasheet)

so 961 is not a valid date code...I think you should check with your provider or may be you didn't correctly read the code.

I hope it could help.

Cheers.

Hi bst-one,

Date-code ''961'' is an early silicon not yet fully qualified in our mass production and is not containing the right boot-loader. Thus, embedded DFU is not working on that early engineering device.  I recommend you ask for free-sample in our e-sampling program and rework the LQFP100 device mounted on your board if you have the adequate equipment. Else you can also contact your local distributor .

Hello,

can you verify that the workaround in AN2606 will help to use the DFU-Bootloader? I can try to pull down PA10 PB5 PD6 as described, but I need verification for the series application,. I have several products here, ready to sell, but i have a random problem to enter the bootloader on startup....

Thanks,

Tobias
