Hi,

as a newbie ive been trying my TS-7200 using cygwin on my pc to 
compile helloworld ok.

Ive got the Video card too and would like to make some use of it but 
im stuck. The TS support helped me by sending the bitblt.c source 
code that mmaps the fb and has a bitblt() function.

However, if i compile it i get nothing - well i do see the login 
prompt still.

I assume that the frame buffer is a (640x480) * 2 byte buffer and 
that code can simply write and read once mapped?

If so why wont ;

int fd = open("/dev/mem", O_RDWR|O_SYNC);

regs = (unsigned short *)mmap(0, 4096,PROT_READ|PROT_WRITE, 
MAP_SHARED, fd, 0x72000000);

fb = (unsigned short *)mmap(0, 640 * 480 * 2, PROT_READ|PROT_WRITE, 
MAP_SHARED, fd, 0x72200000);

allow me access?

And wheres all the other 7592KB gone i.e wont this be linear video 
space?

All help appreciated,


Matt
