CSIA Primary Camera OV5650 does not work with AJ2.2 release

Since you have mentioned this is on a custom board, you need to check the following:

1. Sensor data i/f is CSIA, not CSIB

2. Clock source and frequency is same as on Blaze

3. The position of CSI data lanes is the same

Hello Anaroop,

Check the clock and supply signals to your Camera module as Mayank recommends:

See the state of the listed PRCM registers:

Clock signal - CAM_PHY_CTRL_CLK clock status CM_CAM_CLKSTCTRL[9] CLKACTIVITY_CAM_PHY_CTRL_CLK
Clock signal ISS_CLK clock status CM_CAM_CLKSTCTRL[8] CLKACTIVITY_ISS_CLK
Clock Domain State Transition Control CM_CAM_CLKSTCTRL[1:0] CLKTRCTRL - this must be set to 0x3 HW_AUTO.

Check the register manages the ISS clocks - CM_CAM_ISS_CLKCTRL[1:0] MODULEMODE 0x2 Module is explicitly enabled.

Check the power state of PD_CAM domain - PM_CAM_PWRSTCTRL[1:0] POWERSTATE - 0x3: ON State 

After enabling of ON state, check the power status - PM_CAM_PWRSTST[1:0] POWERSTATEST

Best regards,

Yanko

Hi Yanko.

I have checked the registers 

Camera power domain is active: POWERSTATEST[1:0] = 11

LOGICSTATEST[2] = 1

CAM_MEM_STATEST[5:4] = 11

CM_CAM_CLKSTCTRL:CLKACTIVITY_CAM_PHY_CTRL_CLK[9] = 1

CM_CAM_CLKSTCTRL:CLKACTIVITY_ISS_CLK[8] = 1

CM_CAM_CLKSTCTRL:CLKTRCTRL[0:1] = 0x2 software controled wakeup

CM_CAM_ISS_CLKCTRL:STBYST shows module in standby but 

IDLEST = 0 and OPTFCLKEN_CTRLCLK = 1 and 

MODULEMODE = 2.

Hi Yanko, Mayank,

It appears to be the polarity and may be my debugging screwed but it works with reversed polarity.

But I still have some instability in consistency of the camera preview on multiple close/opens. As well I have some crashes on preview and video recording.

I see FIFO errors instead of the Sensor Timeout. 

Thanks for help.
