Problems while gfxinit() in ginput()

Hello everyone,

I have got a problem. I just tried to implement ginput. There are no errors from the compiler, but the debugger always stops in the gfxinit() routine. I debbuged everything and got to the point where the debugger actual stops. 
It stops always after: port_unlock_from_isr(); in the "chcore_v7m.c" file.

 

I don't know why?
Can anyone help me please?

Sorry. I use the Embest-Base Board with the Touchscreen. I included all the board files and tried to implement the demo /gdisp/basics. Everything went fine. The dispaly worked. But then I tried to implement the Ginput. So I added to the gfxconf.h:

///////////////////////////////////////////////////////////////////////////
// GINPUT                                                                //
///////////////////////////////////////////////////////////////////////////
#define GFX_USE_GINPUT                               TRUE
#define GINPUT_NEED_MOUSE                            TRUE

Here is the full gfxconf.h:
 

#ifndef _GFXCONF_H
#define _GFXCONF_H

/* The operating system to use. One of these must be defined - preferably in your Makefile */
//#define GFX_USE_OS_CHIBIOS	FALSE
//#define GFX_USE_OS_WIN32		FALSE
//#define GFX_USE_OS_LINUX		FALSE
//#define GFX_USE_OS_OSX		FALSE

/* GFX sub-systems to turn on *
#define GFX_USE_GDISP			TRUE

/* Features for the GDISP sub-system. */
#define GDISP_NEED_VALIDATION	TRUE
#define GDISP_NEED_CLIP			TRUE

///////////////////////////////////////////////////////////////////////////
// GINPUT                                                                //
///////////////////////////////////////////////////////////////////////////
#define GFX_USE_GINPUT                               TRUE
#define GINPUT_NEED_MOUSE                            TRUE

#endif /* _GFXCONF_H */

When I set GFX_USE_GINPUT and GINPUT_NEED_MOUSE to FALSE everything works again.

But with both on TRUE the Debugger stops after port_unlock_from_isr(); in the "chcore_v7m.c" file.

I didn't changed anything at the main.c from the gdisp/basics Demo.

Do you need more Information?

Does the program jump to a hard fault handler? It seems that you are using ChibiOS and in some cases it catches overflows etc and gives an error message of what went wrong. If that is the case that can tell you what is going on.

It might be a good idea to look at an example project in the "demos/modules/ginput/keyboard".

I just tested an existing example. The Debugger also stops in the _ginputInit() routine while mouse Initialization.

void SVCallVector(void) {
  struct extctx *ctxp;

#if CORTEX_USE_FPU
  /* Enforcing unstacking of the FP part of the context.*/
  SCB_FPCCR &= ~FPCCR_LSPACT;
#endif

  /* Current PSP value.*/
  asm volatile ("mrs     %0, PSP" : "=r" (ctxp) : : "memory");

  /* Discarding the current exception context and positioning the stack to
     point to the real one.*/
  ctxp++;

  /* Restoring real position of the original stack frame.*/
  asm volatile ("msr     PSP, %0" : : "r" (ctxp) : "memory");
  port_unlock_from_isr();
}

The Debugger Stops after port_unlock_from_isr(); in the SVCalVector() Function. The Program doesn't jump to a hard fault handler.

The actual stack size is:

LDFLAGS  = -Wl,--defsym=__process_stack_size__=0x0800 -Wl,--defsym=__main_stack_size__=0x0800

Do I have to change both, main_stack_size and process_stack_size. Is the stack size big enough?

This stuff seems to be buried in what looks like chibios code. It certainly doesn't look like uGFX code.

I have a couple of suggestions for you...

1. Try to debug and find out what the last line that was executed in the uGFX code and we might be able to help you find a cause.

2. Contact the chibios forums as it definitely looks like a chibios problem.

ok, i tried 0x1000 for stack

file. That didn't worked.

Here is my gfxconf file:

The last line that was executed in the gfx files is: 

i2cMasterTransmitTimeout(&I2CD1, STMPE811_ADDR, txbuf, 2, 0, 0, MS2ST(STMPE811_TIMEOUT));

in the "gmouse_lld_STMPE811_board.h"

 

Thanks for the help :)
