It crash when I plug Marcello mezzanin!

Test with my normal PSU : is it a short? Nop, it is just a lot of capa to charge really fast! -
Maybe a spike of current, add a big capa to test! 100uF isn't enough, because I got 1.6mF to charge! -
Maybe the short circuit protection? On the charger side or MCU side or at the STM32 USB C interface chip? -
The bigger 65W chargers seams to be working fine!

Could have a "soft start" mode that starts at low voltage and grow the voltage to the requested target over 100ms or even 500ms?
