Flash hex file to stm32f412 with uart using stm32cubeprogrammer

[Vaishnavi]

Tried flashing stm32f412 custom controller using uart but facing error while going to boot mode.

I need to flash my hex file to custom stm32f412 board but unable to connect using uart and facing issue while erase memory

Better to open a new thread and share your schematics.

You've marked this as solved.

Are you now saying it is not solved?

Lest' keep this thread closed as he's at first time using wrong UART pins.

Most probably the issue is on his HW. Keeping the discussion on this thread  by sharing the schematics.
