hi,

 

I am new to nor flash driver hope to get some help here.

We are trying to access Nor flash (Micron parallel nor )mapped to 0xe8000000 on our T1040rdb reference design.

Our CFI query (0x98) is failing.

 

mw.w 0xe8000555 0xaa

mw.w 0xe80002aaa 0x55

mw.w 0xe8000555 0x90

mw.w 0xe8000555 0x98

 

And read back the device information

md 0xe8000000.

 

 

we are not able to read the contents.

 

1) Do we need to do any IFC setting to start the Nor flash read?

 

 

 

Thanks

Vijay
