Linking with error: "cannot move location counter backwards"

[lefebvresam]

Description of defect

When compiling and linking I get the error:

:~/git/hmipanel/mbed-os$ mbed-tools compile -m HMC20 -t GCC_ARM
...
/home/sam/git/hmipanel/cmake_build/HMC20/develop/GCC_ARM/source/hmipanel.elf.map
/usr/lib/gcc/arm-none-eabi/10.3.1/../../../arm-none-eabi/bin/ld:/home/sam/git/hmipanel/cmake_build/HMC20/develop/GCC_ARM/mbed-os/targets/TARGET_STM/TARGET_STM32U5/TARGET_STM32U575xG/mbed-stm32u575xg.link_script.ld:90 cannot move location counter backwards (from 0000000020005640 to 000000001ffffc00)
collect2: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.
ERROR: CMake invocation failed!

I created my own device and updated pinning files as described in the howto’s.

custom_targets.json:

Solved by defining RAM and ROM size.
