This is a work in progress Explains what to change in order to build the 2.6.31 LF Explorer kernel for Didj. Use your DJHI to boot the zImage from uSD.
1. make lf1000_ts_defconfig
2. edit .config. (we are enabling jffs2 and giving the right bootargs):
CONFIG_CMDLINE="mem=18M mlc_fb=0x01200000,0x01200000 init=/sbin/init console=ttyS0,115200 root=31:06 ro rootflags=noatime rootfstype=jffs2 ubi.mtd=Brio ubi.mtd=prg_Brio ubi.mtd=Cartridge"
CONFIG_JFFS2_FS=y
3. edit line 184 of linux2.6/Makefile to point to your cross compiler (or comment it out if you know the varaible is set elsewhere).
4. edit include/asm/mach-types.h (the number has changed to 2028 - but the boot loader only knows about 1235)
(you may need to 'make' once and ctrl-c to get the mach-types file generated the first time.)
//define MACH_TYPE_ZIR2412 1235
define MACH_TYPE_DIDJ 1235
...
//define MACH_TYPE_DIDJ 2028
5. edit drivers/mtd/nand/lf1000.c (using didj's 9 partition scheme)

6. make
zImage is found in arch/arm/boot
To mount /Didj:
mount -t vfat -o async,noatime /dev/mtdblock9 /Didj
