Hi,
Has anyone successfully interfaced the DVEVM to a CMOS sensor? I'm
attempting such an interface, but I have faced several weird bugs.
Hope this thread can be used to discuss any bugs in the frontend.
1. I used a Micron sensor with inverted syncs. I tried setting the
VDPOL/HDPOL bits under all combinations and failed to get it to work.
I used an external inverter on the syncs and I could get an image. Has
anyone succeeded using any video capture device with inverted syncs?
2. I was having problems with my CFA coefficients and decided to
conduct a simple write/read test using running numbers on the preview
engine tables using the following code. The code was run with preview
engine disabled.
for(i=0; i<0x1640; i++) {
reg_write(PREV_SET_TBL_ADDRESS, i);
reg_write(PREV_SET_TBL_DATA, i % 256);
reg_write(PREV_SET_TBL_ADDRESS, i);
readback = reg_read(PREV_SET_TBL_DATA);
if(readback != i % 256)
printk("offset=%x writedata=%x readdata=%x\n", i, i % 256, readback);
}
