I'm trying to obtain VGA resolution 640x480 at 30fps with Zybo-Z7 Digilent demo project. The project run smooth with the HD resolution but I need 640x480. I patch 720p60fps preset{
//[7:4]=0010 System clock divider /2, [3:0]=0001 Scale divider for MIPI /1
{0x3035, 0x11},

Hello,
I'm trying to obtain VGA resolution 640x480 at 30fps with Zybo-Z7 Digilent demo project. The project run smooth with the HD resolution but I need 640x480. I patch 720p60fps preset{
//[7:4]=0010 System clock divider /2, [3:0]=0001 Scale divider for MIPI /1
{0x3035, 0x11},
//[3:0] Output horizontal width high byte
{0x3808, (640 >> 8) & 0x0F},
//[7:0] Output horizontal width low byte
{0x3809, 640 & 0xFF},
//[2:0] Output vertical height high byte
{0x380a, (480 >> 8) & 0x7F},
//[7:0] Output vertical height low byte
{0x380b, 480 & 0xFF},
}
I used the existing R640_4860_60_NN timing_t struct I just change the polarity to positive as my device need. But it doesn't works.
Is someone could provid a working preset ?
Thanks by advance.
Regards
