Does OpenOCD support stm32u5a5 microcontroller?

Does OpenOCD support stm32u5a5 microcontroller?

I use xPack OpenOCD v0.12.0-3 to program stm32u585, and it works fine. 
However it fails with stm32u5a5. The command is:

openocd -f interface/stlink.cfg -f target/stm32u5x.cfg -c "program 
$(BUILD_DIR)/$(TARGET).elf verify reset exit"

The output from terminal I get is:

openocd -f interface/stlink.cfg -f target/stm32u5x.cfg -c "program 
Out/system_u585.elf verify reset exit"

I can connect with both targets and identify them with Cube Programmer, 
so the hardware seems to be OK. I found this thread:

https://community.st.com/t5/stm32-mcus-products/problems-using-latest-standard-openocd-build-with-stm32u5a9j-dk/td-p/631770

I copied openocd binaries and scripts from stm32 IDE installed on 
different machine but it didn't help. It gives error as below. The 
stlink.cfg file is in the interface directory.

openocd -f interface/stlink.cfg -f target/stm32u5x.cfg -c "program 
Out/system_u585.elf verify reset exit"

Did anybody encountered similar problems?
