Hi
I want to read/write the value of register NVCSI_STREAM_0_PP_EN_CTRL_0, and I executed as folllows:

echo on > /sys/devices/platform/host1x/13e40000.host1x:nvcsi@15a00000/power/control
echo on > /sys/devices/platform/host1x/13e40000.host1x:vi0@15c00000/power/control
echo 1 > /sys/devices/platform/host1x/13e40000.host1x:nvcsi@15a00000/acm/force_on
echo 1 > /sys/devices/platform/host1x/13e40000.host1x:vi0@15c00000/acm/force_on

And read result

devmem2 0x15a1000c

this will hang

Dear @erfeng.jef,
We will check internally on this issue. May I know if the steps are part of documentation? If so, could you point me to it?

Hi @SivaRamaKrishnaNV
I found this step on DRIVE OS 5.2 for Xavier csi-debug,and adapt this to DRIVE OS 6.0.4 for Orin.

Thanks

Dear @erfeng.jef,
These commands in csi-debugare not supported on DRIVE Orin. Please see Debugging CSI Capture Errors if it helps.

Hi @SivaRamaKrishnaNV
Ok, Is there any other way to read or write the values of these registers on Drive orin?
such as NVCSI_STREAM_0_PP_EN_CTRL_0

Thanks
