I'm trying to debug a Zephyr RTOS application on the STM32H573I Discovery board using the STM fork of openocd and the on-board STLink. I'm running the tools on a Mac M1 machine, and building and flashing the code works fine, using the Zephyr west based toolchain and VSCode.
But when I start openocd with this config (copied from STMCube IDE):
# This is an genericBoard board with a single STM32H573IIKxQ chip
# Generated by STM32CubeIDE
# Take care that such file, as generated, may be overridden without any early notice. Please have a look to debug launch configuration setup(s)
source [find interface/stlink-dap.cfg]
set WORKAREASIZE 0x8000
transport select "dapdirect_swd"
set CHIPNAME STM32H573IIKxQ
set BOARDNAME genericBoard
# Enable debug when in low power modes
set ENABLE_LOW_POWER 1
# Stop Watchdog counters when halt
set STOP_WATCHDOG 1
# STlink Debug clock frequency
set CLOCK_FREQ 8000
# Reset configuration
# use hardware reset, connect under reset
# connect_assert_srst needed if low power mode application running (WFI...)
reset_config srst_only srst_nogate connect_assert_srst
set CONNECT_UNDER_RESET 1
set CORE_RESET 0
# ACCESS PORT NUMBER
set AP_NUM 1
# GDB PORT
set GDB_PORT 3333
# BCTM CPU variables
source [find target/stm32h5x.cfg]
it connects:

but when i try to connect to the server with gdb it reports:

Error executing event gdb-attach on target STM32H573IIKxQ.cpu:

Is this a bug with the STM openocd, or is my config broken ?
Thanks
