Hi all, i'm using STM32F407VG Discovery with expansion board. I have two questions:

1 - Why when i try to connect my smt32f4 using the 5V pin and the GND pin with an external power supply without a USB connection my C application sotred in the flash of my STM32 don't start (i try to remove the  ST-LINK jumpers on the board but the problem remains) 

2- Anyone know the maximum power consumption of the STM32F4 + EXP board... I see on my supply 160mA. It's too much?

Thank you very much for the answers!

Bruno
