It seems values that calculated by sensor_mirror_flip are incorrect.

translated from chinese

In Subsampling mode, the lower 2 bits of FRAMW_HST (address: {0x3204[2:0], 0x3205[7:0]}) and FRAMW_WST (address: {0x3208[2:0], 0x3209[7:0]}) need to be configured as 2’b00, and the lower 2 bits of FRAME_HEND (address: {0x3206[2:0], 0x3207[7:0]}) and FRAME_WEND (address: {0x320A[2:0], 0x320B[7:0]}) need to be configured as 2’b11.

without 2’b00 and 2’b11 i got image like this. may it is related only to my camera.

array size bug. dgain_table_size != 255 ( 15 * 16 )
