Cannot debug STM32MP157D-DK1 engineering mode "Info : Halt timed out, wake up GDB."

[MB11]

I am trying to debug a simple application on the CM4 processor on a STM32MP157D-DK1 development board in engineering mode using Cube IDE Version: 1.18.1

The board is booted from the micro SD card and appears to be powered up and alive with various flashing LEDs.  When I try to debug my simple application I get the following error.  I have tried many different debug and connection options on the debug configuration but I cannot seem to get past this point.  How can I fix this?

I'm getting the same issue. Anyone find out what the problem is?

Hi, @MB11 

your message contains contradictory information, either you boot from SD-Card or you are in engineering mode.

Please look at https://wiki.st.com/stm32mpu/wiki/STM32CubeIDE#Arm-C2-AE_Cortex-C2-AE-M_debug_on_STM32_MPU_device
