Hello all,
I have got a custom designed board using STM32L562QEI6, in which the MCU doesn't boot up upon powering up the board. However, upon pulling the NRST pin low manually and then releasing it, the MCU does power up. I have checked the voltages before and after asserting NRST and everything is stable and as per expectation. This observation was noted every time and followed the same behaviour.
On other boards using the same design, this issue doesn't exist.
Hoping to find some help in this regard.
