Hi experts
psdk_rtos_auto_j7_07_00_00_11 Whether to enable DSI continuous clock mode?
dsi output:
prm.timings.width = 1280U;
prm.timings.height = 720U;
prm.timings.hFrontPorch = 110U;
prm.timings.hBackPorch = 220U;
prm.timings.hSyncLen = 40U;
prm.timings.vFrontPorch = 5U;
prm.timings.vBackPorch = 20U;
prm.timings.vSyncLen = 5U;
prm.timings.pixelClock = 74250000ULL;
Configuration above. The data channel on the DSI has a periodic voltage of more than 1V,
Set the oscilloscope trigger level to 800mV and monitor the data lane activity. If the DSI source is properly
configured to output periodic LP-11 pulses, then the scope should trigger at least once per frame. The period of
the frame is defined by the video refresh rate - commonly 16.6ms for 60Hz refresh. If the scope does not trigger
from the 800mV level, then the DSI source driver has not been properly configured
prm.timings.width = 1280*2U;
prm.timings.height = 720U;
prm.timings.hFrontPorch = 110*2U;
prm.timings.hBackPorch = 220*2U;
prm.timings.hSyncLen = 40*2U;
prm.timings.vFrontPorch = 5U;
prm.timings.vBackPorch = 20U;
prm.timings.vSyncLen = 5U;
prm.timings.pixelClock = 74250000*2ULL;
The configuration of this. The data channel on the DSI does not have a periodic voltage above 1V,
Why does this configuration have no periodic 1V output
