Hi All,

am working on ar1820 sensor  with CX3 controller .

 here taking raw firmware in 10 bits of depth.

it's working fine on some boards exactly out of 10, 5 are working boards and 5 are not working for the boards.

Settings Details:
4 lane - 576Mbpl[MIPI Clock]
24line -  96Mhz[Parallel Clock]

resoution - 4912x3684@9fps.

debugging steps:
1. checked error register on Toshiba 

MIPI-CSI Protocol and Physical Layer Errors in CX3... - Infineon Developer Community

it looks Multi-Data Lane Sync Byte Error Count and Unrecoverable Packet Header Error .
thing is Lane sync error happens in lanes 2 and 3 alone.
 
is there a Lane alignment register present in the Toshiba? or any related solutions?

Thanks for your effort in this matter.

Hello @VediGovind ,

 

Can you please let us know whether you are using your own custom board? If yes please confirm if MIPI lane routing is as per this KBA ..? 

EZ-USB™ CX3 troubleshooting guide - KBA233853

 

Please confirm if you are using MIPI sensor compliant to MIPI CSI-2  (Version 1.01, Revision 0.04 – 2nd April
2009)

 

Thanks & regards,
