Wrong value of VCAP capacitors in STM32F407VGT board

[LMI2]

I have 10uF (=10uF+100nF)ceramic capacitors for VCAPs in a custom board. Voltage there is 2.7V. Supply voltage is 3.3V

I have problems getting the STlink to accept the board. First I managed to erase the chip, now STLink does not even recognise the chip. A dead CPU already?

Are 2.2uFs really needed, I try keep number of stored values here as small as possible.

I guess you are using an LQFP package...

I guess you had a bridge somewhere.

Flux makes the rework 100x better.

Do you use a microscope ?

all my board use LQFPs, for expedient repair of prototyping issues.
