Dear all,

Thanks for the valuble feedback.

I succeeded in recompiling my runtime by replacing -mcpu=cortex-m4 with -march=armv7e-m; Yes, I'm aware the runtime will require considerable tweaking to make it tick properly.

For the Cortex-M7 however it seems the flag -mfpu=fpv4-sp-d16 needs to be replaced with -mfpu=-fpv5-sp-d16 to use the hardware FPU. The later option is also not supported in GNAT GPL 2015 (20150428-49) :-/

So yes, support for the Cortex-M7 overall seems to be too premature right now.

Kind regards,
Stijn
