[BUG] OpenOCD init failed while using specific pin

[Kurburis]

This bug happened while trying to solve this issue: #364
Bug description
BLCDDriver6PWM function needs 6 pins, With a specific pin I am able to build and upload the code to the board once, but after that it is not possible to upload any code via platformio. To return the board to normal, I have to upload any code via STM32 Cube program.

Hardware setup
Board: STM32 Nucleo F303RE
Pin that causes the issue: PA13
Pin functions: https://i.imgur.com/xuleuID.png

Code
Code that causes the bug:
BLDCDriver6PWM driver = BLDCDriver6PWM(PA9, PB0, PB14, PB15, PA12, PA13);
It does not depend on the argument position or the value of other arguments, according to my testing. The only thing necessary is to have PA13 as an argument.

What does your platformio.ini file look like, if I may ask?

Of course, you shouldn't use pa13 or pa14

Of course, you shouldn't use pa13 or pa14

Are they reserved for something I am not aware of?

[Candas1]

Yes, for programming the chip 😂

Thanks!
Is it confirmed on page 55 of the manual:
