Hi all,
I am using custom board based on db820c. I am able to read sensor chipid (5640) during probe but i2c communication fails during launching the camera. Any one met this issue? It seems sensor is not responding. I have checked all voltages, MCLK, reset sequence, all are proper.
Below is the error message.
[ 37.550335] i2c-qcom-cci a0c000.cci: master 0 queue 0 timeout
[ 37.550456] i2c-qcom-cci a0c000.cci: cci i2c xfer error -110
[ 37.555217] ov5640 3-0078: ov5640_write_reg: error: reg=3008, val=2
Thanks,
Pradeep
