[Qemu-discuss] StellarisWare graphics example on Stellaris LM3S6965 hangs

[Lars Hamren]

Hi,

I have tried running the small graphics example from StellarisWare,
in directory boards/ek-lm3s6965/graphics:

    qemu-system-arm -M lm3s6965evb -kernel gcc/graphics.bin -s -S

After connecting with gdb, I can single step or run the program,
but it hangs trying to do SSI writes. Here is the stack trace:

   #0  0x000009b0 in SSIDataPut (ulBase=1073774592, ulData=0) at ssi.c:554
   #1  0x00000252 in RITWriteData (pucBuffer=0x2000004c "", ulCount=8) at 
../drivers/rit128x96x4.c:427
   #2  0x00000296 in RIT128x96x4Clear () at ../drivers/rit128x96x4.c:483
   #3  0x0000038c in RIT128x96x4Init (ulFrequency=1000000) at 
../drivers/rit128x96x4.c:854
   #4  0x00000104 in main () at graphics.c:320

and the source for SSIDataPut:

   554    while(!(HWREG(ulBase + SSI_O_SR) & SSI_SR_TNF))
   555    {
   556    }

It hangs on line 554.

Am I doing something wrong?
