Additional SDRAM input using CS1

youngsangcho · ‎02-12-2021

Hi,

I'm trying to use an additional SDRAM(total 2 SDRAM) to RT1064.

It is connected CS0(GPIO_EMC_29) to the first SDRAM as EVK board and I'm going to use SEMC_CSX0(GPIO_EMC_41) for CS1 of the second SDRAM.

However, an error occurs in the MUX_CSX0 PIN as shown below.

Is it an MCUXpresso Config tool bug or I can't use the SEMC_CSX0(GPIO_EMC_41) pin for SDRAM CS1?

Thank you,

YC

Hello,

It is possible to use SEMC_CSX0(GPIO_EMC_41) as CS1 for the second SDRAM.
Customers can use i.MX Pins tool.

Yuri.
