Subject: atmel_nand pmecc on 8k page
Date: Thu, 12 Jun 2014 14:28:36 +0200	[thread overview]
Message-ID: <CACqcpZDTj-XaPOyH+Twhku26eSa-S3p3xDOWszAQC7JKfOyfsA@mail.gmail.com> (raw)

Hi,

I'm working on a series of patches, to support 8k nand page in
atmel_nand driver.

Currently, I can detect the nand and handle an oob size of 448. But i
have a problem with the pmecc, when barebox tried to perform pmecc
operation, I get the following message:

PMECC: Timeout to calculate error location.

Example of log:

nand: NAND device: Manufacturer ID: 0x2c, Chip ID: 0x68 (Micron
MT29F32G08ABAAAWP), 4096MiB, page size: 8192, OOB size: 448
atmel_nand atmel_nand0: Initialize PMECC params, cap: 8, sector: 1024

atmel_nand atmel_nand0: PMECC: Timeout to get ECC value.
nand_bbt: error while writing bad block table -110


I don't know/find why barebox get a timeout...

Someone have an idea ?

Best regards,
Raphaël
