About AM335x Fast External Boot

Guru 15520 points

Hi,

I have a question about AM335x Fast External Boot.

1.
What is difference and advantage between "Fast Exeternal Boot" and "XIP Boot" ?
Is it only the difference in whether PLL is set up by ROM Code?
I read the TRM but didn't uderstand differenc and advantage of both.

2.
In which situation, should I use Fast External Boot?

3.
If I choose Fast External Boot,
GPMC pin listed in "Table 26-9 Pins used for NOR Boot" will be set by ROM code,
am I correct?

best regards,
g.f.
