Dear ALL:

      Our customer designed a S32V234 customt's board,and we have already patched the s32v234_sdk\os\linux patches.But when debugging the Sequencer Driver, after insmod seq.ko, the system reported an error:

We found that it was caused by the statement in Sequencer Driver in the following figure :

Clearing the KRAM region causes the system error.

At the same time we found such a passage in Sequencer_Driver_Software_User_Guide.pdf:

So,is it due to "security engine" causing an error when loading seq.ko?

If so, how do we burn the "security fuse"?

Is there any relevant documentation?

CPU: s32v234

Uboot:2016.01

Kernel:V4.1.26

BSP:Auto Linux BSP V17.0

SDK:VisionSDK S32V RTM1.2.0
