What error messages do you get?
I see is ECC errors for every read such as the following. mtd->read(0x400 bytes from 0x0) returned ECC error read(0x7c3c bytes mtd->from 0x3c4) returned ECC error
I also noticed a bunch of magic bitmask erros such as the following. jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0007861c: 0x0162 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00078620: 0x61c8 instead
It looks from your e-mail thread that there is a problem with the write.jffs2
implementation. Is this
problem in the 1.2.0 version of u-boot?
No, I don't think so. This thread was related to problem with the rewrite of the U-Boot NAND subsystem. The current implementation should handle writing images (YAFFS, JFFS2) just fine. Please make sure that you use the ".jffs2" extension.
I wrote the image by doing (my file system partition is at offset 0x460000 and my jffs2 image size is 0x288000 downloaded to 0x80700000): # nand erase 0x460000 0x288000 # nand write.jffs2 0x80700000 0x460000 0x288000
I can successfully write this same image from a booted Linux system using the "nandwrite" command.
Do you know if there is a fix for this?
Please let me know if you have more information.
It would be much better, if you wrote to the mailing list too. This way many people could try to help out here. So I suggest to
send you
question again to the list.
I am including the list here. Any help someone can give on writing a JFFS2 image into NAND Flash would be greatly appreciated.
Thanks.
Best regards, Stefan
