Maybe I'm doing something stupid here. It's the first time I mess with
uBoot shell.
Are you editing NOR or NAND uBoot? You have write access only to NAND...
I tried to make a jffs2 image from koolu source code, but I had no
luck. I compiled the sources successfully with "make
PRODUCT_TARGET=freerunner", then I tried to create a jffs2 image
following a very simplistic and probably wrong approach:
1. Created a directory newandroidfs,
2. Extracted the contents of out/target/product/freerunner/ramdisk.img
to that directory, using file-roller,
3. copied the files under out/target/product/freerunner/system to /system,
4. created a symlink /etc to /system/etc and a directory /sdcard (like
I saw in Sean's image)
5. and created a jffs2 image with the contents of the directory
newandroidfs using the command "mkfs.jffs2 --pad=0x700000 -o
newandroidfs.jffs2 -e 0x20000 -n -dnewandroidfs/"
Outcome of all this, red light flashing!!! It's kernel panic, right? :(
It should be...
Btw another way for getting working images, I guess that should be using
the Sean's image as base and then putting there only the files you've
changed with your patches after a recompilation...
Would it work?
If someone (have no ideia who :) ) did a simple tutorial about how to
produce the precious jffs2 image, that would make the testing of new
features a lot simpler.
I'm asking this too :P
I use a script to copy out of the opensource build into my NFS mounted
area. Once there, I use another script to create the jffs2 image. You'll
probably need to modify them to your environment.
