Hello. Aurix team.

I'm using development studio and i have an issue that a variant is not updated with assignment operator.

please see below picture.

leekings_0-1671614341120.png

all variables are 'global variable'(can i monitoring local variable? i tried to see it, but i failed)

in line 746,  rawData = g_rx_L_POS_u16[1]; is operated.

and current break point is line 764.(between line 746 ~ 764 is hidden)

refer expression window, rawData is zero and g_rx_L_POS_u16[1] has it's own value.

i checked g_rx_L_POS_u16[1] has value before implement line 746.

 

and i set rawData's initial value as 0x10, but rawData is set zero after implement line 746.

when i do debugging step by step, sometimes g_rx_L_POS_u16[1]'s value is transfered to rawData sucessfully.(1~2time when i try 10 times)

but when i set break  after line 746, it is set as zero 100%.

do you know why this phenomenon happening?

 

please help me. thank you.

 

please help me.

 

thank you.

If this is a bug, then Zero you seen is not real. You can use a judgment statement to test. Otherwise I used below code to test ADS 1.8.0 and looks OK. You can try below code to test also.
