Powered up newly designed board today.
Of course it seems not to work. :-(
Its based on Discovery board.
I currently have only the STM portion populated.
The Oscillator pins are both low. Using a 8 Mhz Xtal and 20 pf caps. I would of expected one high one low and oscillating.
Part is STM32F407VGT6
I seems to have 3.3V and 1.8 on P73 and P49
Reset goes both low and high with reset switch.
Seems to draw 7.5ma.
Anyone got a checklist to go through? Ohmed out power and ground on board. Might have missed something. But doubt it.
I believe I have PDR and Boot0 and Boot1 properly.
Other than the obvious that the board does not work any ideas?
Will not connect using ST-Link V2.
Where I am shooting myself in the foot?
