I'm using STM32MX Cube to assign pins for different features.
I have a lot of communication ports and GPIO:s enabled in my STM32H750.
I have prototype 1 working, I noticed that when I add for instance an extra I2C other pins move without notice. For instance, LTDC RGB pin R0 moves to another pin on STM32.
I have also seen that LTDC is disabled suddenly wihtout any notice.
Quesiton. Is it possible to lock current pins in STM32MX cube?
Else How do I see all pins that changed when I add a new I2C? is there any log file?
This is a bit stupid from my point of view. And it may cause a lot of issues in next revision of this board if I dont tanke my time and check all 240 pins...
Thanks,

Hmmm... just saw the "Keep current signals placement" option in the "Pinout" pop-up menu I mentioned above. This does NOT put thumb tacks on all the pins but does claim to prevent Cube from moving all signals. One click and you are done.

Yes - right-click on the pin and click on "signal pinning". You should then see a thumb tack icon on that pin. This gets tedious on large pin count devices. A possibly easier way is to click on the "\/ Pinout" menu in the light blue bar across the top, then select the "Pins/SIgnals options" menu. This brings up a dialog that lists all the pins. You can then click on each line in the "thumb tack" column to pin each signal. Still tedious but quicker than right-clicking on each pin in the chip view.

That was the setting I was looking for:-)
Have a great day!
