I think I’ve got the same problem, but since this is my first time ever with a STM32 I don’t know what to look at in LinkerScript (I’m experienced with Arduino, but working with STM32 is totaly different).

My linker script (STM32L4R9AIIx_FLASH.ld) looks as follows:
But first the result I got when running any samples from the STM32Cube_FW_L4_V1.13.0 firmware in System Workbench for STM32 on a Macbook.

I have exactly the same problem... Did you managed to solve it? It would be very useful for me to know how.

Thanks in advance for your help!
