Sure, Scott, not blame on you. Just frustating, doing bughunting for
issues that have been fixed long time ago. I would expect a bit more
from TI in this case. My fault obviously.
Ok, finally I got it, that's what matters.

It's not older versions I'm concerned about, but newer ones. This bug
has b
I have been used u-boot supportet (or better say not suppported) by TI
in their latest PSP/SDK (Juli 2011).
Base is 2010.06. But this issue was also inside older versions.

Hi all,
I would be very interested in using that patch (it is very use

I am feeling to spam the board but found finally the reason for this behaviour.
nand_read returns with -EUCLEAN in case of correcting errors, and this
will later on reported as BAD NAND, although this error is corrected.
Correct me if I am wrong. What I did is chaning env_nand.c:
while (a
I think reason that SW_ECC is not working, is in omap_gpmc.c:
omap_nand_switch_ecc():
case NAND_ECC_SOFT:
nand->ecc.mode = NAND_ECC_SOFT;
/* Use mtd default settings */
nand->ecc.layout = NULL;
printf("SW ECC selected\n");
I did tests with OMAP3 uboot. The SW-ECC (testet 1 bit, 4 bit BCH)
doesn't correct errors in environment (during power-up).
Compiling uboot for default HW-ECC - correction works fine.
Testet with TI's PSP 4.02.00.07 (almost like arago latest version).
I modified single bits by adding a patch (than
