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
we are not able to read the contents.
1) Do we need to do any IFC setting to start the Nor flash read?
