we have a customized having stm32f769bitb MCU. i am able to connect JTAG in hotplug mode but when im trying normal and other mode i m getting error as "cant reset the core". also i tried connect under reset im getting the same error. the custom board has schematic similar to stm32f769i eval board. can anybody suggest where could be the problem??
i am able to see the power supplies are also ok providing 3.3v as well as 5v.
thanks in advance.
