Question

STM32CubeMX disables SWD by default for F1

Posted on November 12, 2016 at 23:43

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.

Clive,

When is it desirable to do that?

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.

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.
