Hi @oshawkat ,
It looks this unit still had “DRIVE-V5.1.6-E3550-EB-Aurix-With3LSS-ForHyperion-StepA-3.05.04” and hasn’t been installed with DRIVE OS 5.2.0.
Please “don’t” mess up the two units and “don’t” install DRIVE OS 5.2.0 on this unit.
For this topic, please try to flash IFW firmware (as you did in Aurix MODMGR_ERROR preventing device boot - #22 by oshawkat) to collect the information for our analysis. Thanks.
