I'm having trouble getting SWO to work using openocd on the NUCLEO-H743ZI2 board. I've removed SB26 as per the user manual for this board. This should leave the SWO pin (PB3) connected to the stlink SWO, meaning I can get ITM output over the usb connection, right?
I've enabled ITM with openocd with `monitor tpiu config internal itm.fifo uart off 8000000`. I've tried a few different frequency values instead of 8000000, but none seem to make any difference.
This board does support SWO output with the built-in stlink right?
Lastly, the manual is quite confusing in a few places. For instance, SB26 is bridged by default, but the only reference to it in the manual says to remove it for connecting SWO. Why would it be bridged by default then? Does it have another use that isn't mentioned? Another spot in the manual says: "SBxx can be found on the top layer and SB1xx can be found on the bottom layer of the Nucleo-144 board." But, unless I've somehow misunderstood this sentence, this is clearly wrong. There are plenty of SBxx on the bottom layer..
