Problems running app on new STM32F407G-DISC1 pcb
Hi,
i replied to this discussion:

but i guess the board is a better place for it? Maybe someone could move it here.
In short, the original poster and me both have similar problems with the new stm32f4 discovery pcb (STM32F407G-DISC1). The app will not run if only powered from micro usb; i think it has to do with a new ST-Link (ST-LINK V2A compared to the old ST-LINKV2) that is on the newer boards. According to
In fact, it's easier than this. ST released a new firmware for ST LINK (STSW-LINK007) that removes the requirement for USB host to be present. If your device exhibits problems, try upgrading the firmware (mini USB side). It only deals with the "bootloader" side; it's not necessary to re-flash the F407 chip.
