openocd freertos awareness can't start gdb

I have a setup with openocd and arm-none-eabi-gdb and I'm trying to debug a FreeRTOS fw.

I start openocd with:

openocd -f /usr/local/share/openocd/scripts/board/stm32f0discovery.cfg -c "stm32f0x.cpu configure -rtos auto"

That command works fine.

Then I run arm-none-eabi-gdb -tui and at the end of my .gdbinit I have:

target remote localhost:3333
monitor reset halt
file build/fw.elf
load
continue
focus next

But when I try to stop <ctrl>-c and start continue my fw all I get is the error:

Cannot execute this command without a live selected thread.

What am I missing?

I'm using a JLink Base debug probe.

My case is a bit different than yours, with a setup using QtCreator and its Baremetal plugin, but found a bug report where they state a workaround:

https://bugreports.qt.io/browse/QTCREATORBUG-18436

The workaround is pretty easy:

in GDB Init commands add "info threads" after load command. It fixes issue.

I tried it, and it worked, the error message was removed, and now I can see the different tasks in FreeRTOS.
