SYSCONFIG: EMIF resource conflict

Part Number: SYSCONFIG

Hello team,

I am trying to configure EMIF for 16-bit SRAM. I have only one SRAM IC which is selected via EM1CS2n (pin 70).

In Pinmux Use Case, I get following message: Non-required pin enabled: EM1CS3n & Non-required pin enabled: EM1CS4n. In PinMux Peripheral and Pin Configuration, I get Resource conflict for EM1CS4n (pin 64). Shown in below snap.

I do not intend to use EM1CS4n (pin 64) for SRAM in my design, so I have used it as a GPIO.

Please guide me, how can I get this resource conflict resolved. Is there any condition that these pins should be reserved and not used as GPIO.

Regards,

Ritu
