hi,

i recently got stm32f407vg-disc1(discovery) and started a project.

i want to power up the board with external battery(5.1v, 2.4a) through micro-usb port(cn5) but it's not working at all.

it's working fine when i plug it with PC.

my english is not that good so i'm having a hard time understanding a datasheet.

any suggestions?

best regards,

chang
