I am trying to make some very low current (<1uA) power measurements on the MCU on the STM32U083C-DK demo board.I see that jumper `JP7` is provided specifically for this purpose, but I am concerned that connections from the MCU to the STLINK interface...

I've checked the documentation tab on the product page and also in the user manual, but can not find it.Is it available somewhere?Thanks,josh

>I don't think anyone really expects the ST-Link section to talk to the mainboard MCU by telepathy.The two sides need to talk to each other, but the path by which they do so should be manifest rather than hidden.On the TI boards, there are no traces ...

These Nucleo boards are actually kind of ironic because they copy the superficial *shape* of an air-gappable DMZ, but they have traces that sneak across the gap...This *exactly* misses the point! :)

Ah yes, I too have had similar experiences - hence this post. ;)TI does a nice job of putting a DMZ between the debugger/programmer and the MCU and adding jumpers on every line that crosses the DMZ so you can visually verify air-gap for evaluation.If...

I have a Joulescope for making the Actual measurements, the line "Always remove the debug probe and power cycle before measuring current." from the linked document is critical since there does not seem to be a way to disconnect the debugger from the ...

Perfect, thank you!
