Tool/software:

HI,

    I have two code projects, the initialization function is the same, the startup function is the same, the hex file compiled by the same compilation environment, the same development board, but the two projects download to the development board, the initialization time is not the same, from the power-on start to the main() function between the beginning of the time is not the same, what is the reason?

    Hi,

    We have .cinit function called inside code_start which initializes all the variables. Based on how many variables are there in each project, execution time will be different. Instead of main, you can check the time to start of code_start.
