hello elfmimi, wondering how to use it, is it use with the openocd? do you have the script, wanna to have a try.

I'm glad to know your interest in this. yes openocd . I'm not aware of any other software that could be used with.

I used LonganNano (GD32VF103) and RaspberryPi Zero (BCM2835) for testing nanoDLA-JTAG .
But both of these are very tricky to start with.

edit: I can confirm it also works with STM32F103.
I've not yet tried, so I will test it later, but if it were to perform good with STM32F103, the command line will be like this.

just resetting:
openocd -f interface/usb-jtag.cfg -f target/stm32f1x.cfg -c "init; reset; exit"
downloading and programming firmware:
openocd -f interface/usb-jtag.cfg -f target/stm32f1x.cfg -c "program firmware.elf exit"
openocd -f interface/usb-jtag.cfg -f target/stm32f1x.cfg -c "program firmware.bin 0x08000000 exit"
starting gdb server for debugging:
openocd -f interface/usb-jtag.cfg -f target/stm32f1x.cfg

note: on Windows WinUSB driver must be assigned to USB ID 16c0:06ad using Zadig (or equivalent).
