STM32WL error flashing with enabled LoRa middleware using OpenOCD

No source files or tests are named. Start by reproducing the minimal GPIO project and then the project with SubGHZ and LoRaWAN enabled, focusing on the stm32wlx OpenOCD flash path and the failed write at 0x20009ff8. Done means the LoRa-enabled STM32WLE5CCU6 project compiles and flashes successfully through OpenOCD.

Hello everyone,

I have an Olimex BB-SMT32WL that is based on a STM32WLE5CCU6. I use STM32CubeIDE and opened a new project for exactly the STM32WLE5CCU6.

Firmware Package Name and Version STM32Cube FW_WL V1.3.0

If I just configure like a GPIO Output to High it compiles and I can succesfully flash and debug it using STM32CubeIDE and openocd gdb running via terminal.

But as soon as I open the .ioc and simply enable SubGHZ and LoRaWAN things stop working, while it still compiles it won't flash anymore, throwing me this error:

(I also tried Arduino STM32duino but I'm getting the same error..)
