Hi all,

My development environment is PX2. The sample_camera_multiple_gmsl work fine on drivework-0.21 version(beta 1). After I upgrade to drivework-0.3(beta 2), I get failure by executing sample_camera_multiple_gmsl. Below is the log.

Hello simon750324,

Could you check Aurix F/W version? I think you need to update Aurix FW. Thanks.

Hi Steve,

How to check Aurix F/W version and update Aurix FW?

Thank you.

Hi Steve,

Another question.
Which version of Aurix needs to be updated for DriveWorks 0.3.400 version?

Thank you.

Hello KentTeng,

Could you please see below doc(Page51~58) for aurix flashing? Thanks.

Please see /VibranteSDK/vibrante-t186ref-foundation/utils/scripts/DPX2-P2379-EB-V2.01.03_release.zip in Beta2.0.

Hi Steve,

The aurix version is 2.01.03, it should be newest version.
Do you have any idea for this problem?

Thank you.

Hello KentTeng,

Yes, Aurix version is 2.01.03.
I can run the app successfully with same command sudo ./sample_camera_multiple_gmsl --type-ab=ar0231 --selector-mask=0001
Could you please check camera type, camera connection(A gropu)…?
If not please try to re-flash DPX2 PDK Beta 2.0. Thanks.
