Hello Im using RT1050 NXP chip

And I need 128MB QSPI Flash memory and 128MB SDRAM.

Is it possible to using 128MB SDRAM?

I wish to use 32MB SDRAM x 4 CS.

I wanna know how to configuration those settings( Hardware and Software ).

Is there any manual for setting external RAM?

I read reference manual(SEMC). but I didn't undeerstand..

I need more sepcific tutorial for using more than 3 chip select for extenral RAM

Thanks for reading

SEMC of RT1050 supports 4 Chip Select (CS) each CS supports up to 64MB. Unfortuanately, there is no detailed guide besides the SDK examples, you might refer to the RT1170 example since the EVK connects two SDRAMs.

You need to connect every buses and signals between RAM chips but exclude only CS signals, because CS should be connected independently.
