AM335x GPMC as 100MHz

RY9983

Hello,

There is following description on TRM(spruh73h P251):
Up to 100 MHz external memory clock performance (single device)

- If we use GPMC as 100MHz, it is supported only one device. Right?

- My customer needs to connect both FPGA as 100MHz and NOR Flash as asynchronous mode.
Is it supported on GPMC?

Hi RY,

I don't see any problem here. Async. devides don't use the GPMC_CLK, so it will be connected only to the FPGA. There are seven chip select signals available. Don't forget that if you want to boot from NOR it will need to be on CS0.
