<mawk> a real one PaulFertser
<mawk> is it because of the swd_hla mode maybe?
<mawk> maybe they didn't route reset properly to the debug header though, that's a possibility
<mawk> I need to check the schematic
<PaulFertser> mawk: I'm asking because some cloned stlinks had srst miswired.
<mawk> right
<mawk> well it looks like a real one, I even think they have the original box somewhere
<PaulFertser> mawk: you can always run openocd with -d3 and you'll see the log lines where it says how it operates the signal. It's known to work in swd_hla for sure.
<PaulFertser> mawk: guess you can check with a 'scope to be 100 % sure.
<PaulFertser> So probably yes, the reset might be not routed to the connector on the target board.
<mawk> is "TRST" the same thing as SRST? that's how they call the reset pin on the schematic
<PaulFertser> mawk: surely not
<PaulFertser> mawk: TRST is JTAG State Machine reset, and just that.
<PaulFertser> Unless the particular vendor decided to abuse it for something else.
<mawk> it's a connector that does both JTAG and SWD apparentlty
<mawk> but I use it in SWD mode
<PaulFertser> See where it goes to on the MCU
<mawk> ah
<PaulFertser> It's most probably a mistake of whomever developed the board. TRST is mostly useless, you can do the same by state transitions in JTAG.
<mawk> not on reset
<mawk> it goes to PB4
<PaulFertser> So it doesn't need to be on the connector at all.
<mawk> right
<mawk> weird that they did that
<PaulFertser> Stupids
<mawk> I'll send a list of changes I want to make to the board design company
<mawk> there's a few mistakes
<mawk> and I'll tell them to add a tagconnect port for the modem UART
<mawk> making my life infinitely easier
<mawk> or something better than tagconnect if it exists
<PaulFertser> When do you expect the next iteration with the changes?
<mawk> in a few months or maybe a year
<PaulFertser> Faster to learn fine soldering under a microscope :)
<mawk> lol
<mawk> yeah
