Hello,

I have the following problem:
with buildroot-2011.11 I have generated file system, kernel (3.1.4) and u-boot. The board starts and everything works fine except for one small flaw that bothers me. When starting the kernel providesthe following output:

...
at24 0-0050: 1024 byte 24c08 EEPROM, writable, 16 bytes/write S3C24XX NAND Driver, (c) 2004 Simtec Electronics s3c24xx-nand s3c2440-nand: Tacls=1, 9ns Twrph0=3 29ns, Twrph1=2 19ns s3c24xx-nand s3c2440-nand: NAND soft ECC
NAND device: Manufacturer ID: 0xec, Chip ID: 0xd3 (Samsung NAND 1GiB 3,3V 8-bit)
Creating 4 MTD partitions on "nand":

*uncorrectable error : *
0x000000040000-0x000000060000 : "u-boot-env"
*ftl_cs: FTL header not found.* 0x000000060000-0x000000560000 : "kernel"

*ftl_cs: FTL header not found.*
dm9000 Ethernet Driver, V1.31
...

Has anyone an idea how I can remove the bold warnings? These warnings
seem to be generated by the file linux-3.1.4/drivers/mtd/ftl.c (line 180). Unfortunately I have no idea how I can fix this problem and hope for
your expert help.

This question doesn't seem to be related to buildroot, but rather to MTD.
Try the MTD mailing list at linux-mtd at lists.infradead.org.

I can hazard a guess though: is it possible that your memory card is not
formatted (or simply isn't there)?

Regards,
Arnout

Thanks for the note. I boot from NFS, but the NAND device on the Board was formatted and configured the U-boot. The solution for my problem was disabling CONFIG_FTL option in the kernel config (thanks to Peter K.)

Regards
Andrei
