HI
The Reference manual states "Programmable master clock generation (operating from fixed 48-MHz functional clock input)"
Is 48 MHZ the Max speed of the SPI ?
Regards
Eby

Usually - but not always - such detail is available w/in the "spec." portion of the MCU manual. (far to the rear) An SPI specific table should reside there - and should answer.

Suspect your post has not properly landed (here) as few mentions of AM335X arrive this forum wasteland...

The AM335X maximum SPI_CLK frequency is 16MHz in Slave mode and 48MHz in Master mode. See section 7.12 from the AM335X Datasheet Rev. H for details.
