What is the meaning of the setting value of WEIM_ADDRS(page-1545) in the MCIMX7D RM

[tamotsu]

Hello.

I don't understand the meaning of the WEIM_ADDRS(page-1545) setting value in the MCIMX7D refernce manual.

Posible values for EIM-CS are 128MB, 64MB, 32MB and 0MB.

The value at reset is 0x10, whitch is explained as 128MB.

I want to set to 4 CSs. Please tell me the value of set. And please tell me its meaning.

Best regards.

The supported configurations are:
CS0(128M), CS1 (0M), CS2 (0M), CS3(0M) [default configuration]
CS0(64M), CS1(64M), CS2(0M), CS3(0M)
CS0(64M), CS1(32M), CS2(32M), CS3(0M)
CS0(32M), CS1(32M), CS2(32M), CS3(32M)

WEIM_ADDRSx[ ]

00 = 32 MByte
01 = 64 MByte
10 = 128 MByte

WEIM_ACT_CS0=1, WEIM_ADDRS0=01

WEIM_ACT_CS1=1, WEIM_ADDRS1=00

WEIM_ACT_CS2=1, WEIM_ADDRS2=00

I'm sorry, there's a mistake.

The setting value was 0b10 instead of 0x10.

Best regards.
