[BUG] OpenOCD init failed while using specific pin #366

Closed Kurburis closed 8 months ago

Kurburis commented 8 months ago

This bug happened while trying to solve this issue: https://github.com/simplefoc/Arduino-FOC/issues/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?

Yes, for programming the chip 😂 https://youtu.be/jEz0C2bT2M0?si=82EXkqy8ii4tdhug

Thanks! Is it confirmed on page 55 of the manual: https://www.st.com/resource/en/user_manual/um1724-stm32-nucleo64-boards-mb1136-stmicroelectronics.pdf
