I am using TivaC 1294, which has 256K internal SRAM. However, we need more RAM, so we want to add an external RAM of size about 2M or 4M bytes via EPI.
According to the datasheet, EPI can support SDRAM, SRAM and PSRAM. However, I couldn't find any reference design (schematic, code example) about them.
So could anybody tell me where to find reference design and code example?
I think PSRAM/SRAM should be my favourite verus SDRAM, but any suggestion is appreciated.
Thanks
