[U-Boot-Users] [PATCH] mtd: CONFIG_NAND_LAZY_SCAN option support
With this option set, the nand_init() doesn't scan NAND for bad blocks.
This allows one to avoid boot delays caused by the scanning procedure for
the boards which do not need NAND for booting.
To work with NAND having this option set, one should explicitely call
nand_lazy_scan_finish() before using the NAND chip. This function
automatically
called at the first access to NAND chip from the U-Boot command line.

At this point, for performance reasons, I abandoned any effort to use JFFS2

So, as of today, I am running u-boot-1.3.3 and am booting a boot.itb
multi-image containing a compressed Linux kernel + FDT DTB out of NAND
using 'nboot':
= printenv bootaddr bootcmd boot0 boot1
bootaddr=80

run addjffs2 addtty bootm ${bootaddr}
boot1=nboot.i ${bootaddr} 0 1C0 setenv bootargs
root=/dev/mtdblock11 run addjffs2 addtty bootm ${bootaddr}
During the time I was evaluating JFFS2 on the AMCC PowerPC 405EXr Haleakala
board, I do not recall having any compilation issues or having to tweak the
build beyond the necessary CONFIG_/CFG_ settings.

So I'm not to familiar with how the CPU specific files should be laid out. Did the config commands change to set up Ethernet? The Ethernet driver for the chip is under cpu/arm920t/ep93xx/eth.c Nothing fundamental has changed in how Ethernet drivers are initialized. I'm afraid you're going to have to roll up your sleeves and figure it out yourself. printf will be very helpful. There's no 'ep93xx' in the source code.

This seems to imply that the kernel is looking for the clean markers.
If they are not needed
with NAND flash then why would it look for them? I did not see
anything in the kernel configs
for JFFS2 that would tell it to use use them.
As I said before this is kernel 2.6.18, an older version of build root
using mtd_20050122
Any other thoughts?

Regarding the above three errors, you may be interested in the following
patch and referenced thread:
http://lists.infradead.org/pipermail/linux-mtd/2008-June/022008.html
u-boot nand erase clean 50 1b0
I cannot speak to your specific board; however, I found that 'clean' was not
necessary and used the following sequence to write a JFFS2 image to Samsung
small-page NAND on my PPC405EXr-based board:
= tftp 80 root.img
= nand erase 80 140
= nand write.i ${fileaddr} 80 ${filesize}
Adjust sizes and offsets accordingly for your board.

Grant Erickson

[U-Boot-Users] [PATCH RFC] ARM: Davinci: NAND fix for large page ECC and linux compatibility
U-boot's HW ECC support for large page NAND on Davinci is completely
broken. Some kernels, such as the 2.6.10 one supported by
MontaVista for Davinci, rely upon this broken behaviour as they
share the same code for ECCs. In the existing scheme, error
detection *might* work on large page, but error correction
definitely does not. Small page ECC correction works, but the
format is not compatible with the mainline git kernel.
This patch adds ECC code that matches what is currently in the
Davinci git repository (since NAND support was added in 2.6.24).
This makes the ECC and OOB layout written by u-boot compatible with
Linux for both small page and large page devices and fixes ECC
correction for large page devices.
The code depends on a #define CFG_LINUX_COMPATIBLE_ECC, which is
undefined by default, making the default state backwards compatible.
I have verified this by compiling without the #define and producing
a binary byte-for-byte identical to one without this patch.
[NOTE: I have not yet been able to get my hands on a board with
small-page NAND to test, but large page does work. If anybody is
interested in testing it, please do and let me know if it works for
you (i.e. uboot with this patch and davinci git kernel can
read/write the same NAND).]
