Sorry, your screenshot is illegible. Please explain what you are seeing and why it does not match what you expect to see.

Note that if you are seeing different behaviour between a Debug and a Release build of your project, then this is probably down to optimisation...

Thx for your answer

I correct the picture and it’s the problem
As you see the value of the variable of the Rx_Buf in the debug mode is different as the real value
Rx_Buf is in memory address of 0x10000228
When I click left mouse on the variable of Rx_Buf[0] a window show the values as below
Rx_Buf[0] = 1
Rx_Buf[1]=24
Rx_Buf[2]=1
Rx_Buf[3]=24

When I check the address of 0x10000228 value of this address is 0x18011801
Its mean
Rx_Buf[0] = 1
Rx_Buf[1]=18
Rx_Buf[2]=1
Rx_Buf[3]=18

i most notice this : the real answer we expect is 0x18011801

Decimal 24 = hexadecimal 18 :bigsmile:

You might find this FAQ useful - towards the bottom it explains how to change format
