Hello Laszlo, no such patch in gerrit yet, so I don't expect anyone is doing it. Nevertheless it's an interesting improvement. > Here is how the config would look like. > > ---------------------------------------------------- > adapter driver linuxgpiod > transport select swd > > # SWCLK (PC6) > linuxgpiod_swclk_gpiochip 2 > linuxgpiod_swclk_num 6 I would prefer to avoid adding new commands, you can extend the "linuxgpiod XXX_num" command: 1) or simply dropping the command "linuxgpiod gpiochip <chip>" and making mandatory the dual parameter "linuxgpiod XXX_num <chip> <num>" 2) or keeping the command "linuxgpiod gpiochip <chip>" and adding an optional parameter "linuxgpiod XXX_num [<chip>] <num>". If the optional parameter is missing, the chip value is taken from the command "linuxgpiod gpiochip <chip>" Probably 1) is easier to handle and describe in the documentation. > I actually created patches for various OpenOCD versions and having to > maintain them drives me a bit crazy.
