Hello,

In this case, the connection has been explained in more detail. I hope this clears up your confusion.

Kind Regards,

thank you . VTG is renamed to SWD_SEL . You just need to pull SWD_SEL to VDD, this enables debug/programming out on P20. Also the usual SWD_IO and SWD_CLK connections need to be done along with a direct GND connection between both the boards. my question from where/which pin should i take VTG i.e 3.3v .

Hello,

Please take a look at this old DevZone ticket, which discusses a very similar issue.

Kind regards.
