hunjit reacted to squalyl in hard fault when accessing GPIO configuration registers via AHB
Yes, we crossed messages !
as always, writing about my problem made me find it.
I'm now setting the correct bit in GPIOHBCTL, and it works \o/
So guys, in order to access GPIO via the AHB addresses, you have to set the correct bit for your port in the GPIOHBCTL register, address 0x400fe000+0x06C , page 247 of datasheet !
Hope it can be useful to someone else!

Small update: beware of the GPIODATA register Adress lines 9..2 act as a mask, so it's useless to write at GPIODATA+0x000 See page 608 of datasheet...
The LM4F is the first microprocessor that forces me to do that much RTFM!
