The ecc-mode is "hardcoded" to NAND_ECC_HW in arch/arm/mach-at91/at91sam9g45_devices.c. I've got the same -74 problem when reading from the nand. Barebox fails to read the environment, even if barebox has written it. After changing the ecc mode to soft the env can be read and written without problems. I ported the atmel nand driver from linux-2.6.37, which had no significant differences. cheers, Marc -- Pengutronix e.K. | Marc Kleine-Budde | Industrial Linux Solutions | Phone: +49-231-2826-924 | Vertretung West/Dortmund | Fax: +49-5121-206917-5555 | Amtsgericht Hildesheim, HRA 2686 | http://www.pengutronix.de |
