Sensor windowing problem

OpenMV Boards

After updating the firmware and IDE sensor.set_windowing((213, 133, 213, 213)) don’t work
It generate: RuntimeError: “Frame size is not supported or is not set.”

sensor.set_windowing (210, 133, 213, 213) works fine

Board H7 OV5640 Firmware 4.1.0

Se code below
it seems that x larger than 210 don’t work.

sensor.reset()             
sensor.set_pixformat(sensor.RGB565)   
sensor.set_framesize(sensor.VGA)    
sensor.skip_frames(time=2000)       
net = "trained.tflite"
time.sleep(2)
labels = [line.rstrip('\n') for line in open("labels.txt")]

clock = time.clock()
area=0
count=0

while(True):
    clock.tick()
    area = area +1
    if area == 1:
         sensor.set_windowing((0, 133, 213, 213))
    if area == 2:
         sensor.set_windowing((213, 133, 213, 213))
    if area == 3:
        sensor.set_windowing((426, 133, 213, 213))

    img = sensor.snapshot()

Previous versions of the driver didn’t check DMA buffer line sizes and etc. This is not a bug. The resolution you want to crop to cannot be done. We use hardware acceleration now so the actual pixel line with has some more constraints. Make the width even.
