Long story short: I use the mkfs.jffs2 + sumtool to generate the JFFS2 image and the U-Boot to flash it into my NAND. When I turn my board on it boots, but not without displaying a few error messages... Oh, and sometimes it crashes showing (null): : bad variable name.
Does anyone knows what's going on and how can I solve this?
Here the full version...
I'm using a EVM board with the AM3359 processor, which has a 256M NAND.
The first thing I did was change the kernel in order for it to be able to use a JFFS2 filesystem (http://processors.wiki.ti.com/index.php/Filesystem_in_NOR_or_NAND#JFFS2).
Then I use the following to generate the JFFS2 image I use:
mkfs.jffs2 -e 128KiB --no-cleanmarkers -r rootfs/ -o rootfs-jffs2.img
sumtool -n -e 128KiB -i rootfs-jffs2.img -o rootfs-jffs2-summed.img
Note that I don't use the -p option.
Finally, U-Boot flashes the image via a SD-Card:
mmc rescan
nandecc hw 2
nand erase 0x00780000 0x0F880000
fatload mmc 0 0x81000000 rootfs-jffs2.img
nand write.trimffs 0x81000000 0x00780000 0x00A50000
And I use 0x00A50000 because it's greater then the image size. I also use nand write.trimffs instead of nand write.jffs2 because of this: http://processors.wiki.ti.com/index.php/Put_JFFS2_Image_to_Flash#NAND_Flash
So, after all that is done, I try to boot the kernel. The thing is that it does boot, but nevertheless it shows some error messages before it shows the login. At times, it crashes with the message :
(null): : bad variable name
I'm copying the log here if anyone wishes to see whats going on. Thanks a lot!
Uncompressing Linux... done, booting the kernel.
