[nucleo-f767zi.zip](https://github.com/user-attachments/files/19637559/nucleo-f767zi.zip) *Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary This is the pull request for the changes I've done for the stm32 nucleo-f767zi board, fixing the issues to use the buttons. More information can be found at this ticket: https://github.com/apache/nuttx/issues/16097 The 'core' fix was include the /dev/buttons at stm32_bringup.c file but it was not the only change. I have also added here the same logic used on stm32f103c8t6 (blue pill). This change was needed otherwise the buttons subsystems won't run at all. ## Impact Basically I've removed the internal board button by for GPIOs to be used by the user (for sure it is the main impact). At least now we can run the button subsystem. ## Testing I have test if for 1 week and although I've test it, and worked very well with 4 external push-buttons, there is 2 situation it is still not working. A – When I added 8 buttons, only 5 worked. It is NOT a hardware problem since I tested all the buttons with an oscilloscope. It’s also not an issue with the GPIOs I chose, because when I mix the GPIOs but use only 4 buttons, everything works as expected. However, when I use 8 buttons, the GPIOs that were previously working stop working completely (again, I can see the pulses on the oscilloscope, but there’s no feedback on nsh). B – Probably related to issue A. When I add the built-in button along with the 4 external buttons, the built-in button stops working. But when I use only the built-in button, it works fine.  -- This is an automated message from the Apache Git Service.
