How to use AM335x GPMC to manage 32 bit bus

Frank Wu95

TI ICE design with AM335x is using GPMC with D-ff to control 16 bit bus, but I need to control 32 bit bus, is there any way to implement it?

Thanks,

No, the GPMC has a 16-bit bus width on all Sitara devices.

Do you think we can do something like this?

If you connect an FPGA to the GPMC you will probably be able to convert the data bus width, but this is not a use case TI supports. Support will be limited to getting the GPMC bus running only.
