mx25 and 16x SLC NAND problem

Hello everyone,

I was wondering if anyone can shed any light on the problem I encountered
trying to get 16x Micron SLC NAND (MT29F2G16AA; 2K page, 64byte spare area
and 128K erase block) to work with Freescale i.MX258 SoC.

Description:
=========
(1) I am booting successfully from NAND.
(2) When I try to save the environment, it seems that write works (saveenv)
and I can verify that all the data is realy properly written to the  NAND
(nand dump 40000 20000)
(3) Data in the OOB area also seems logical: first 9-byte ECC sequnce
(calculated for the first 512-byte subpage  that actualy contains the data)
is different from 3 other (mutualy identical) ECC sequences calculated for
the empty subpages.
(4) reset produces :
"MXC_NAND: HWECC uncorrectable ECC error in block 2 page 128 subpage 0"
(which points to where I have my env offset set to (0x40000) with no
redundant area)
"*** Warning - bad CRC or NAND, using default environment"

My Troubleshooting:
================
* I tried using different block to store the environment and all of them
behave the same (as stated above).
* I double-checked i.MX258 datasheet to make sure that NFC (v1.1) is
properly initialized (4-symbol ECC and all relevant  NFC/CCM registers)
* I tried Freescale's version of the U-boot (released as a part of their
Board Support Package) with worse results (their u-boot version seems to be

Re: Where can I find the git repostory for mx51evk

Hi Denk,

	It seems that "git am" doesn't work for me.

	The steps are:

	1. Save the patch as txt file in outlook and copy to u-boot directory.
	2. Use git am to apply the patch.

Re: [PATCH V4 10/11] fsl_esdhc: add support for mx51 processor

Hi Stefano,

	Have you tested mmc on mx51 board?

	The original esdhc uses PIO mode in function esdhc_send_cmd(), while fsl_esdhc uses DMA mode.

	I hasn't tested DMA mode before.

	BTW: have you considered add the feature to save environment data to mmc?

	Thanks~~

Yours
Terry

The esdhc controller in the mx51 processor is quite the same as the one in some powerpc processors (MPC83xx,
MPC85xx). This patches adapts the driver to support the arm mx51.

Yes, you are right, good catch. The following patch will help:

Dear "Lv Terry-R65388",

Well, I'm afraid there is little we can do to help you with that.
Setting up a basic working tool chain is something you have to do
yourself; we don't know your environment. If you don't succeed
yourself, then ask another, more experienced engineer in your team
for help, or some support guy.

Maybe you should try and avoid working in a Windows based environment
here. I have no way how many wonderful ways Outlook knows to mess up
the messages it processes.

We are using git versions 1.6.2.5 and 1.6.6 (i. e. what comes with
recent Fedora distributions).

The problems you report are not caused by git version differences.

Hi Terry,

> Have you tested mmc on mx51 board?

Yes, of course. The whole patchset for mx51evk was tested on two
different releases of the board, with respectively a TO2 and a TO3
processor.

And the driver was tested with both MMC slots on the mx51evk (both are
supported):

For example, on a release 3.0 board:
U-Boot 2009.11-00347-g0b1898d (Feb 24 2010 - 11:30:10)

CPU:   Freescale i.MX51 family 3.0V at 800 MHz
Board: MX51EVK 3.0 [POR]

I get:
MMC:   FSL_ESDHC: 0, FSL_ESDHC: 1

MX51EVK U-Boot > mmcinfo
Device: FSL_ESDHC
Manufacturer ID: 1
OEM: 5041
Name: SP02G
Tran Speed: 25000000

Do not do it. Even if it for some strange seems working (it could be for
an  easy patch), you apply a patch different as the one sent to the ML.
The correct step is to save the e-mail as it is. If your e-mail client
does not support it, take another one.

This is really caused by your client and tells you that the e-mail was
not correctly saved.

Regards,
Stefano
