Bus error

The hardware is a BF527-EZKIT based custom board.

What exactly does it means?

Is there any solution already?

The error information says:

So, please debug the QtGui library to see why it access misaligned data.

Message: 80020   

I've run some experiments, as this worked before (with the ezkit '527)

When I build ucLinux for my board (but with "CONFIG_FB_BFIN_T350MCQB=y" (ezkit's LCD) ) it works, but when I build it for my driver it fails with:

Data access misaligned address violation

- Attempted misaligned data memory or data cache access.

Bus error

As the diference between the builds is only in the LCD drive, that makes me thinking that the problem is somewhere there... but have no idea...

What could be the reason?

The LCD driver is based on the ezkit's LCD driver...

If you want us to review your driver - you need to post/attach it. Otherwise there isn't much we can do.

Hi,

these are two versions of the video driver file - one is working, the other is not.

The difference is only in DMA mode and the LCD timings and few settings. Cannot see something that may couse such a behaviour...

Any comments are wellcome.

I found where the problem is.

With:

    fbinfo->var.red.offset = 0;

    fbinfo->var.green.offset = 8;

    fbinfo->var.blue.offset = 16;

it's working, but with:

     fbinfo->var.red.offset = 11;

     fbinfo->var.green.offset = 5;

     fbinfo->var.blue.offset = 0;

it fails...

I'll need yours expert comments ...

Message: 80199    Nikolay,

Looks like QT gets confused with your drivers COLOR formats - RGB565

versus RGB888

It sounds to me that you like to use RGB565...

Please fix your:

static int bfin_ra158z_fb_check_var(struct fb_var_screeninfo *var,

struct fb_info *info)

Function - it still tells that RGB888 is a valid format...

Hi Michael,

Thank you for pointing that!

I've changed it to:

    case 16:

        var->red.offset = info->var.red.offset;

        var->green.offset = info->var.green.offset;

        var->blue.offset = info->var.blue.offset;

        var->red.length = info->var.red.length;

        var->green.length = info->var.green.length;

        var->blue.length = info->var.blue.length;

        var->transp.offset = 0;

        var->transp.length = 0;

        var->transp.msb_right = 0;

        var->red.msb_right = 0;

        var->green.msb_right = 0;

        var->blue.msb_right = 0;  

        break;

,but it still ffails with:

        fbinfo->var.red.offset = 11;

        fbinfo->var.green.offset = 5;

        fbinfo->var.blue.offset = 0;
