DM365 NAND read error

Ankur Tank

We are trying to bring up custom board based on DM365,

We are trying to boot from the NAND,

NAND used is from micron MT29F8G08ABABA.

Organization
– Page size x8: 4320 bytes (4096 + 224 bytes)
– Block size: 128 pages (512K +28 K bytes)
– Plane size: 2 planes x 1024 blocks per plane
– Device size: 8Gb: 2048 blocks

and 4bit ECC

we made changes to Uboot to get it detected by Uboot.

In "drivers/mtd/nand/nand_ids.c" added below line

{"NAND 1GiB 3,3V 8-bit", 0x38, 0, 1024, 0, LP_OPTIONS},

And in "include/configs/davinci_dm365evm.h"

Removed #define CONFIG_SYS_NAND_PAGE_2K

Added #define CONFIG_SYS_NAND_PAGE_4K

Added #define CONFIG_SYS_NAND_4BIT_HW_ECC_OOBFIRST

Existing #define CONFIG_SYS_MAX_NAND_DEVICE 1

With above changes initially NAND write started working and we could book the Linux kernel.

But Linux kernel was not able to detect the NAND partitions.

We started experimenting in Linux and suddenly NAND read stopped working from Uboot.

We get error code "failed -74". Below is boot log,

Now my doubt is what could be error in NAND Read ?

What is this code -74 ?

Any help is appreciated.

Thank you,

Adding some more information

on nand read following output is printed

DM36x EVM # nand read 0x80700000 0x1000000 0x100000

Please let me know if you any suggestion for this...

thank you,

Adding some more information, below log shows nand write is fine but nand read is not working.

Below log shows nand dump of write address also to confirm that nand write is working fine.
