  1. it seems i have problem in “ RAM(g)[xyaddr(x, y)] &= ~xybit(y) ; ” because when I use keil bebug and running at this code,the mcu will goto“ void HardFault_Handler(void)” but I think the really problem is “ g->priv = gfxAlloc() ” yes that function. my configuration are : //#define GFX_USE_OS_WIN32 FALSE //#define GFX_USE_OS_LINUX FALSE //#define GFX_USE_OS_OSX FALSE //#define GFX_USE_OS_ECOS FALSE //#define GFX_USE_OS_RAWRTOS
  2. It seems be stuck at the _gdispInit(); function.
