Hi guys,who knows what the best to connect STM32H743 to a computer for debugging?

I know what you re saying! I recon with a st link it is enough ! than it is to identify the bug and to fix it is the hardest job to do!

yes sure,I agree wit that! I ve just got an st link and from getting info online ,there re few options available

I d rather connect the stlink to the board however mineone in the picture has different cabling so hard to get the pins out to know what function it does.
