CTL_RESULT_ERROR_AUX_INCOMPLETE_WRITE when ctlAUXAccess for writing

[dunli]

I got the error code CTL_RESULT_ERROR_AUX_INCOMPLETE_WRITE = 0x48000015, ///< AUX incomplete write failure
when I call ctlAUXAccess(hIntelOutput, &AUXArgs) for writing,below is my sample code:

				ctl_result_t Result = CTL_RESULT_SUCCESS;
				ctl_aux_access_args_t AUXArgs = { 0 };
				AUXArgs.Size = sizeof(ctl_aux_access_args_t);
				AUXArgs.OpType = CTL_OPERATION_TYPE_WRITE;
				AUXArgs.Address = SliveId;
				AUXArgs.DataSize = Length + 2;//data + 2 byte offset
				AUXArgs.Data[0] = (uint8_t)((Register & 0xff00) >> 8); //our usage 
				AUXArgs.Data[1] = (uint8_t)(Register & 0x00ff);

				for (int i = 0; i < Length; i++)
				{
				    AUXArgs.Data[i + 2] = SendData[i];
				}
				Result = ctlAUXAccess(hIntelOutput, &AUXArgs);
				if (CTL_RESULT_SUCCESS == Result)
				{
					return 0;
				}
				else
				{
					return Result;
				}

before writing ctlInit and ctlEnumerateDevices relative functions all called with no error.
Our application senario is aux over I2C and now I want use PC to R/W the DP monitor control IC registers of our own.
B.T.W my app exe is 32bit and I use ControlLib32.dll and my CPU is Intel Core Ultra 9 185H ,my graphic card as follows:

@murali-i @ashutosh-d-shukla @rahulrgandhi99 and other friends
Would you pls give me some suggestions?thx a lot!

We will check and revert back on this. Any specific reason for 32 bit exe/app? The processor should support 64 bit exe too.

Hi Shukla,
Thanks for your reply!
our project app exe has a long history and 32bit also works well for us. I think IGCL should also support 32bit and AUX functions in ControlLib32.dll also has the same effect as ControlLib.dll,right？

[ashutosh-d-shukla]

Yes 32 bit IGCL should work as well, we will revert back.

What is the value provided for AUXArgs.Flags ?
Is I2C_AUX_Sample_app.exe working on the setup or throws any error ?

Hi Ramani,
my AUXArgs.Flags = CTL_AUX_FLAG_I2C_AUX;
Because I need to use aux over I2C to access our IC for the panel.
I didn't use the flag CTL_AUX_FLAG_NATIVE_AUX in the I2C_AUX_Sample_app, but I can try it.
