I have been having a problem with my STM32H725IGT custom PCB, because I can't flash it even though i tried almost everything. I have tried flashing from nucleo's programmer and from stlink-v2 clones via SWD connection, but none of the STM32Cube programs detect my device.
What i have tried:
+I checked if all of the pins have power and if all of the ground pins are well connected.
+I have checked the voltage on VCAP which is 1.6V so something is working inside I guess.
+I have checked if I didn't mix up header pins and if headers pin have continuity to SWD pins on MCU.
+I have tried setting boot0 to high but it didn't change anything.
