hello:

I am working with c6747, and I want to boot from SPI Flash, and I want to know the time to boot from spi, So I use the scope to test, find that it used 1.2s boot to copy about 40KB  data from flash to ram!

1. I want to know if the time I test is right?

2. when Boot from spi Flash, what is the max speed the spi can use to boot from spi flash ?

thanks!
