问题:我们有几个项目,在项目1和项目2上实现截屏是没有问题的,但是在项目3上实现截屏是不行的
原因:分辨率差异引起的问题,分辨率长宽一定要是32的整数倍
Dear customer,
Sorry for the late reply due to annual leave.
I don't think this issue relates with thedifference between MIPI DSI and LCDC.
I think that this issue relates with stride, thatis to say, which depends on width pixel.
Due to Tiled-based BLT enginee on MDP side, thetiled size is 32(w)x32(h).
For 480(w)x800(h), no this issue, so that 480divided by 32 = 15 (integer). 800 divided by 32 = 25 (integer).
For 240(w)x320(h), have this issue, because that240 divided by 32 = 7.5 (float), need add 16, that is to say, (240 + 16)divided by 32 = 8 (integer), 320 divided
