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?
