I am working on a system designed on stm32mp157c mpu. I am trying to setup a remote debugging setup wherein I am running an openocd debugger script on this stm32mp1 mpu. The target I am debugging is an stm32f405 discovery board, which is connected to the mpu via stlink/V2 in-circuit debugger using SWD. Finally, I will be connecting to the debugger on my remote PC through CubeIDE using the 'Connect to remote GDB server port'.
I was successful in creating the openocd environment at the stm32mp1 end, however, connecting to this via CubeIDE gave me an error.

I have ensured the connections on the stlink side and the configuration on the CubeIDE. Can anyone help me figure out why is this issue happening? Is it related to the openocd version I am using or something else?
TIA.
