Hello,
What is the max SPI speed that AM1808 can support? Can AM1808 SPI runs at 48MHz and if so, would you please provide clock settings for PLL/SPI to do this?
I configured SPI clock for 50MHz (prescale = (150MHz module clk / 50MHz desired SPI clk) -1) but SPI failed to read Device ID of a Winbond SPI Flash.
I was able to read Winbond's Device ID at 37.5MHz (prescale = (150MHz module clk / 37.5MHz desired SPI clk) -1). The Winbond SPI Flash was verified working at 52MHz with a different platform.
Thanks,
Dat
