Hi,
I am trying to reduce the booting time of the processor. so the problems i am facing are
1) how can I measure the boot time?
I went through some TIE2E threads in those threads people are mentioning the booting time but i am not getting any hint how can i measure it.
2) how can I reduce the boot time ?
is there any TI's manual which can explain about the procedure of reducing boot time?
The way I understand the boot time is power up to the execution of first line of main function.
Hi Amit,
The powerup sequence starts at the the release of power-on reset. The LPM HF oscillator will start up first, then the oscillator starts up, then Efuse autoload, flash pump and bank. After flash bank is powered up, the nRST is released.
The datasheet says that the boot time is 3517 oscillator clock cycles.
You can measure the time between the release of nPORRST and nRST.
You can reduce the boot time by using a faster crystal or oscillator. The oscillator start up time is dependent on the type of oscillator. The maximum crystal or oscillator frequency supported by TMS570 is 20MHz.
