I am not able right now to understand what is inside the .ld and .S files.

Since #13509 I received a proper device mounting the stm32l071CZTx and I am now testing it.

I am not able to test the device against an ARM and IAR compiler to check if those files are working.

Then in GCC startup file,
replace
bl __libc_init_array
bl main

by
bl_start
