I'm trying to write code to access NAND devices on the SD EVM for this device. I'm having a basic problem trying to make any kind of bus access on EMIF-A - specifically CS3 never seem to toggle for any accesses in the 0x62000000 range. I see no activity on other EMIF-A pins either, but I'm concentrating on CS3 for now.
I have setup the PINMUX and looked at the EMIF-A control registers, PSC and clock control registers and they all seem to be setup as required by the documentation for EMIF-A accesses.
Any suggestions as to what I might have over looked, or a CCS script to demonstrate a simple read? An dummies guide might help...
