I have an external Static RAM chip connected to the LPC1788 and when I move the GUI RAM from GUIConf.c to external static RAM, emWin crashes in GUI_Init(). Here is my linker file and GUIConf / LCDConf settings. The same behavior occurs whether I use Muliple Buffering or single buffering. If I move GUI RAM back to internal SRAM on the LPC1788 it is not crashing. The VRAM in external SRAM seems to be fine. Attached are my Linker file, GUIConf and LCDConf files.
