Tool/software: Starterware
Hi,
I want to interface 8 bit nand flash (ISSI - IS35ML04G084).
size is 512MB (4096 blocks)
I am using startarware nand interface code used on sitara EVM board
I have done following modification in code
1. instead of wait0, wait1 pin connected
2. disabled AD8 to AD15 pin multiplexing , as I am not using it.
3. NAND ECC algo type used is NAND_ECC_ALGO_RS_4BIT
4. Base addres kept same as 0x10000000 used on EVM board
5. CS region size is same as GPMC_CS_SIZE_256MB (00)
6. FCLK set to 25 MhZ
after NandOpen I have getting following error
"ERROR: DEVICE MAY NOT BE ACCESSABLE OR NOT PRESENT."
I check on CS0 pin using CRO I got just one small pulse of low level of duration 600ns. I got the same pulse width of ALE of high level
Please guide me where I am going wrong.
