TDA4AL-Q1: Can't boot up devices when camera set up on J721E without Fusion1 RevC (UB960)

Hi,

Sorry, didnot get it Are you connecting camera directly to TDA4 EVM? Does this camera output directly over CSI interface and is it compatible with the MIPI connector on the board?

Hi, Brijesh,

Yes, we have a mipi FPC camera OX08B40 sensor, and it needs to connect the TDA4 EVM directly, used by CSI2 port.

And I found a discussion about this case in Forum by

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1366617/tda4vh-q1-how-can-i-connect-a-csi2-camera-directly-i-e-no-fpdlink-with-j784s4-evm

Now, I think it is successful by this way for use.

But now if I connect the camera for TDA4 EVM, it can't into boot mode, shown a black screen, does it not have driver on this sensor?

If yes, how can I do to bring up this driver? Thanks.

Note. the camera module have extender cable from MIPI FPC to Samtech 40-pin.

Hi,

No, we dont have driver for this sensor, but my concern is board not booting up with this sensor. Is the sensor output compatible to Samtech input connector on EVM? Is it affecting some input on EVM?

Hi, Brijesh,

Thanks your reply.

About EVM can't boot up with Samtech input connector on EVM issue, we will check the hw pin of Samtech whether compatible the CSI2 pin.

And could you teach us to bring up the mipi FPC camera OX08B40 sensor? How do we do for the sensor driver firstly?

Is there an document to reference? Thanks your help.

Hi Chen,

Yes, please refer to below link for adding a new image sensor in the imaging layer.

There is also a debug guide for CSIRX at below link.
