I'm using SIS to run it. As far as I know, this is the default target for
the ERC32 BSP, so it should run without problem. I'd like to know if the
call to __bsp_board_init was removed by mistake; if not, why hello_world_c
doesn't run on SIS?

Are you using the erc32 or sis BSP to run on gdb's simulator? The sis BSP
enables extra initialization not required on the real hardware.
