TDA4VE-Q1: Does version 10.1 of tda4veco support MIPI CRC check?

hi xie jc,

Well, MIPI as protocol has CRC data included in the long packet and this is also checked by the CSIRX. If you mean this verification, this is supported by HW.

Yes, this is what I mean. I want to know how to get the verification results

Well, we can register callback to the driver and driver will call this callback whenever this is any CRC mismatch detected.  Please refer to IOCTL_CSIRX_REGISTER_EVENT control command in the CSIRX PDK driver.

Can you give me a patch?

Hi xie jc,

Sorry, but did not understand, what patch are you looking for? This ioctl is already supported in the driver, most likely this is also getting called in the capture node. You would just need to add a callback function in this patch.

OK, I founded it. Aut I saw a print statement in tivxCapturePrintStatus() for "crcCount". ​​Does​​ it also ​​mean​​ a CRC mismatch?

Hi,

Yes, it does report CRC errors even in this count.
