Hi VInoth

one can try turn on/off commands for cameras described in

sect.8.1.1 Interfaces to control the EVS function attached Android Guide.

Thank you Igorpadykov for the reply.

I got some information from your input.

evs/app/EvsStateControl.cpp
mTurnSignalValue.prop = static_cast<int32_t>(VehicleProperty::TURN_SIGNAL_STATE);

source/vendor/nxp-opensource/imx/vehicle/impl/vhal_v2_0/DefaultConfig.h
- .initialValue = {.int32Values = {toInt(VehicleTurnSignal::NONE)}}},
+ .initialValue = {.int32Values = {toInt(VehicleTurnSignal::RIGHT)}}},

I will test and update.

Thanks & Regards,

Vinoth S,

Hi igorpadykov‌

I done those configuration software side but, not working as per exception and finally, I found where the problem,

I changed GEAR_SELECTION default value to park from reverese

diff --git a/vehicle/impl/vhal_v2_0/DefaultConfig.h b/vehicle/impl/vhal_v2_0/DefaultConfig.h
index 03dd662..52fdad5 100644
--- a/vehicle/impl/vhal_v2_0/DefaultConfig.h
+++ b/vehicle/impl/vhal_v2_0/DefaultConfig.h
@@ -907,7 +907,7 @@ const ConfigDeclaration kVehicleProperties[]{
              .access = VehiclePropertyAccess::READ,
              .changeMode = VehiclePropertyChangeMode::ON_CHANGE,
          },
-     .initialValue = {.int32Values = {toInt(VehicleGear::GEAR_REVERSE)}}},
+     .initialValue = {.int32Values = {toInt(VehicleGear::GEAR_PARK)}}},

Default gear value is reverse in simulator and I configured as park. After this I got this default image.

I don't why this makes the problem.

Thanks & Regards,

Vinoth S,
