multi-device using EBI in MPC5675K

Hi,

Can I use the EBI of MPC5675K(BGA473) to control the SRAM(as a cache or running program) and another bus devide(such as a  Nandflash with eight databus) together?

If not ,how can I use these two devices?

 

Thank you!

Hi, EBI module has up to 4 chip select (ebi_cs) lines, thus you may connect up to 4 devices having standard external parallel bus, typically asynchronous or synchronous SRAMs, NOR flashes or various memory mapped external ASIC devices or FPGAs.

Glueless connection of NAND flash to EBI module is not possible, it would require NAND flash controller.
