anyone familiarize UV2 project should know there must be one *.Opt file for each project. who can tell me what's the function of this file? I guess Opt indicate "options", is it right? if it's right, then what kind of options? compile and link options?
Since I am still using old version 3.x of uVision, I ran into this problem. I asked Keil/Arm. Unfortunately, I was told by the person who picked up my question that it is too old and he can't find information of it.
If you save this file in version control, it can be very annoying because every time you save a file in the IDE or do any configuration change and press the save button, this file will be changed - and most of the time the changes should be ignored.
By looking at the line details, you can tell the first 3 numbers are subdirectory, file id, type type.
There is one benefit of having the IDE generating this file - you can use it to verify if your IDE has all the configuration setup correct or not. So my practice is: I save this file in my version control. Every time I commit changes, I do a quick scan to see if everything is correct. However, I do not modify this file. If anything is wrong, I go back to the IDE to fix it.
