I have made a control board with STM32F769IIT6. External 25MHz oscillation does not occur, so chip doesn't work.
PDR_ON is at high, BOOT0 is at high, NRST is at high, BYPASS_REG is at low. VDD12DSI and VCAPDSI is at low with 2.2uF and 100nF. I have put as much as possiple decoupling caps. 25MHZ crystal (Jauch) with 18pF capasitances, they are so close to chip....
