Dear All,

We are using STM32F207ZGT6 in our product which is used for CAN & Ethernet communication.Recently we observed one issue in our board.Board will goto non working condition suddenly and if we connect ST link utility for reprogramming it is showing that readout protestion is enabled(Level 1).We can't bring from Level 1 to Level 0.

In the working board Resistance between VCAP1 / VCAP2  to ground is ~5K.But in non-working board it is around 35 Ohm.We can suspect that internal reulator might goes bad.

Please let me know if anyone faced similar issue.
