hi
these days , i've been working on VPFE resizer . and my platform is dm6437.
as known , the resizer can get its input either from ccdc or SDRAM. and when
input is from SDRAM ,it proves to work all right .that is , the hardware can
insert an interrupt and do its resize workk. but there is a little problem,
though i can do a resize successfully , but i can't see the field
resizer.PCR.busy vary. as a matter of fact , the register is always 0. i set a
breakpoiont,and try to find the changes, with no luck. i guess maybe the DSP
work so effectively ,the registe value PCR.enable is cleared and PCR.busy set
to 1, then an interrupt was declared , all these happens before i can capture
it. anyhow ,it works.
then i focus my attention on that resizer get input from ccdc. Its really
amusing to find that resizer.PCR.busy is always 1.and the resizer cant insert
an interrupt , so resizer fails to work.
is there anyone who have succeed in resizing from ccdc (with no preview )? pls
make some comments .any remarks would be much appreciated .thanks in advance.
