Hello,
I'm using Keil uVision V5.24.2.0 with ARM Compiler V5.06 update 5 (build 528). Initially, compiler optimization level was set to 1.
With this level, I found that the address assigned to a pointer changed, without any modification done by the code. To avoid this I reduced the optimization level to 0 and pointer address remained the same throughout and system reset, didn't occur.
Kindly, help me understand why would compiler optimization effect in such a way?
Here, is what I found www.keil.com/.../armcc_chr1359124221739.htm
Thank you in advance.
