    No mipi errors, but no streaming

      Hello,

       

      We are trying to configure our ar0144 sensor to stream with settings RAW10, 30ips, 1280x800 on the denebola board.

      Camera input xtal is 27mhz

       

      Mipi errors show 0, but AMCap reports no fps and no picture. Debug output:

      Prod = 45 Cons = 45  Prtl_Sz = 22000 Frm_Cnt = 99 Frm_Sz = 1678720 B

      0 0 0 0 0 0 0 0 0

      Prod = 45 Cons = 45  Prtl_Sz = 19568 Frm_Cnt = 100 Frm_Sz = 1676288 B

      0 0 0 0 0 0 0 0 0

      Prod = 45 Cons = 45  Prtl_Sz = 18128 Frm_Cnt = 101 Frm_Sz = 1674848 B

      0 0 0 0 0 0 0 0 0

       

      Scope traces of mipi clk/data, Pclk, HS and VS are shown below. My project is attached.

      mipi clk bottom trace, arithmetic diff:

      mipi clk/data, 1=data, 2=clk

      PCLK

      1=VS, 2=HS

      1=VS, 2=HS zoom (glitches on HS?)

       

      Any suggestions of what to test or try?

      Thank you,

      Rockie
