STM32CubeMX disables SWD by default for F1

I use STM32CubeMX 4.17.0. I create a new project and select any F1. Then, I generate a source code. In function HAL_MspInit() I see following lines:

/**DISABLE: JTAG-DP Disabled and SW-DP Disabled

*/

__HAL_AFIO_REMAP_SWJ_DISABLE();

STM32CubeMX disables SWD by default. Is this a bug?

Is this a bug?

No I think it is a feature. I believe it is a check box item.

Hello,

For F1 series, from STM32CubeMx and Pinout view, go to the SYS peripheral and change ''No Debug'' to any other mode. This will resolve this issue.

Clive,

When is it desirable to do that?

How to recover if the chip is already programmed this way?

Dieter,

I re-generated the project with STM32CubeMX.

And you have to power-cycle the target board.

Then it all worked correctly in the debugger.
