FD registers' values

Ariel T.

Intellectual 825 points

Hi,

For example, when I write a non-zero value to the FD_SIZEX register and then read it out, but the value of FD_SIZEX remain 0, why? (Face detection of DM368)

write to register:

regw_if(config->inputdata.inputImageWidth, FD_SIZEX);

read out from register:

unsigned int valRd = 0x000;

valRd = regr_if(FD_SIZEX);

Anyone can help me? Thanks very much!

Probably looks like the clocks are not enabled. Enable the clock and try it.

Hi Prabhakar,

I don't know what clocks referred to? And where to config them? The ARM Cores: ARM 432 MHz and RTC are already enabled.

Ariel,

Can you check if the part has Face Detect enabled in it, for the Face detect part this needs to have 'F' in its part number

Thanks, Raghu. At last I find it doesn't support Face Detection, for its device name without 'F'.
