Hi team,
One of our customer's issues, I'm forwarding it below, could you please provide some troubleshooting suggestions
When used with 90UB933, there is no MIPI data output. The companion sensor is OV9284.
UB954(0x30) and UB933(0x58) are configured as follows
i2ctransfer -y 1 w2@0x30 0x01 0x07
i2ctransfer -y 1 w2@0x30 0x4c 0x01
i2ctransfer -y 1 w2@0x30 0x58 0x78
i2ctransfer -y 1 w2@0x30 0x5c 0xB1
i2ctransfer -y 1 w2@0x30 0x5d 0xc0
i2ctransfer -y 1 w2@0x30 0x65 0xc0
i2ctransfer -y 1 w2@0x30 0x6d 0x07
i2ctransfer -y 1 w1@0x30 0x6d r1
i2ctransfer -y 1 w2@0x58 0x03 0xd5
i2ctransfer -y 1 w2@0x58 0x05 0x01
i2ctransfer -y 1 w2@0x58 0x0d 0x99
i2ctransfer -y 1 w1@0x58 0x0d r1
After the OV9284 is configured, The 933 data pin and the HSYNC, VSYNC signals are OK
PCLK is 100MHz
However, the MIPI port clock and data interface of the UB954 have no data output.
Best Regards,
Amy Luo
