I tried to upload build output(.axf) into flash of STM32F411, but it failed.
- Internal command error 
- Error: Flash Download failed - Target DLL has been cancelled.

I used STM32F411 Nucleo board pulled out two jumpers for ST-link not Nucleo. Target board is my own board before it succeed on loading. The target board is consists of STM32F411. I started to develop from Nucleo, then moved to target board.

Loading .axf process is succeed on Nucleo, but when I used it as ST-link with the other target board it failed.

Wiring is same as before.

Is there any suspicious things?
