Dear Friends
I am using Embedded Artist board EA4357 with emwin 5.30 M4F library.
All was working fine (Display, Touch etc.)
Hence emwin5.30 doesn't have inbuilt png support, I have downloaded the emwin_png package (emWin_V5.26) from LPCware and included all files in my keil compilor.
Program compiled and run properly (PNG images displayed).
But as i touched the touch screen (anyware in screen) program hangs.
After debugging I came to conclusion that program hangs when GUI_PID_StoreState() function is called.
I don't understand what is the relation between GUI_PID_StoreState and GUI_Draw_png...??
One more thing I observed, when I touched the touch screen, following error (debug) message is printed on serial port.
GUI_Alloc.c:
Dereferencing free block in GUI_ALLOC_h2p().GUI_Alloc.c:
Block is already unlocked in GUI_ALLOC_UnlockH().
Now I am clueless to solve this.
Please Guide me what can be the reason.
Thanks...
Chetan
