Hi @Tommy Murphy, Thanks a lot. I've read the sections you suggested, and got it working! All that needed to be done is modifying the first line in the .gdbinit file:
target extended-remote | openocd -f ../config/flash_config/openocd_probe.cfg -f ../config/flash_config/openocd_chip.cfg -s "C:/path/to/scripts" -c "gdb_port pipe; log_output openocd.log" monitor reset halt monitor flash erase_address 0x8000000 0x00200000 monitor reset halt file foobar.elf load monitor reset run monitor shutdown quit Then I launch GDB in the usual way: $ arm-none-eabi-gdb -x ../config/flash_config/.gdbinit Huray, it works!

From: kristof.mul...@telenet.be <kristof.mul...@telenet.be> Sent: Monday, July 27, 2020 10:29:10 AM To: openocd-devel <openocd-devel@lists.sourceforge.net> Subject: [OpenOCD-devel] Launch OpenOCD from GDB in one console Dear developers, As you might know, I'm working in a startup building a new (free!) IDE for microcontrollers: Embeetle IDE. To flash code we generally use a combination of OpenOCD and GDB. Both are launched as targets from the makefile in two separate consoles. I was wondering if it's possible to flash from just one makefile target (in one console). Let me first explain the way we do it now. The makefile target openocd looks like this: .PHONY : openocd openocd : $(OUTPUT_FILENAME) .elf $(OCD) $(OCDFLAGS) with the following flags: OCDFLAGS_DASHBOARD = -f ../config/flash_config/openocd_probe.cfg \ -f ../config/flash_config/openocd_chip.cfg \ -s " $(dir OCD ) ../scripts " \ -c " init; reset halt " \ Target gdb looks like this: .PHONY : gdb gdb : $(OUTPUT_FILENAME) .elf $(GDB) $(GDBFLAGS) With the following flags: GDBFLAGS_DASHBOARD = -x ../config/flash_config/.gdbinit \ So if the user clicks the flash button, we first launch target openocd and then target gdb shortly after. GDB then runs its commands from .gdbinit , which actually instructs GDB to connect to OpenOCD and initiate the flash: # .gdbinit file target remote localhost: 3333 monitor reset halt monitor flash erase_address 0x8000000 0x00200000 monitor reset halt file foobar.elf load monitor reset run monitor shutdown quit Now is there a way to do all this from just one makefile target, and therefore also from one console? I heard about the possibility to launch OpenOCD from a GDB session, like: (gdb) target remote | openocd ... I tried it, but the console gets locked and no longer accepts gdb commands to be executed.
