For your embedded device you need some environment and busybox is what you need. So download busybox, compile with your toolchain and install (read README how to do this). Then you have some directory structure (/bin /sbin ...) in some directory. Then compress this directory with command at http://open-nandra.com/?p=142 (part initrd creation) and thats it. Just pass then created initrd image to kernel command line and it should work. I see that you're using ext2 filesystem so you can't compress nothing just copy it to rootfs. > > On Thu, Apr 9, 2009 at 6:13 PM, Belisko Marek <marek.belisko@xxxxxxxxx> wrote: >> >> Hi, >> >> On Thu, Apr 9, 2009 at 2:30 PM, Murali N <nalajala.murali@xxxxxxxxx> wrote: >> > Hi, i am porting the "linux-2.6.28.7" kernel onto latest Freescale >> > i.MX35 board.I am able to reach till initrd loading, after unpacking >> > the initrd file, kernel calling the "run_init_process("/sbin/init/")" >> > function.After this kernel is giving panic.I am unable to proceed >> > further from this point,can any one please tell me what could be the >> > problem? >> > Below are the booting message sequence.Also can any one share the link >> > to build "initrd" file for ARM platforms? >> You can follow my example: http://open-nandra.com/?p=142 >> You just need build busybox, install and compress like it's described >> in example. >> > >> > >> > >> > Uncompressing Linux............................................................. >> > ................... done, booting the kernel. >> > [ 0.000000] Linux version 2.6.28.7 (root@danny) (gcc version 4.2.2) >> > #15 PREEMPT Thu Apr 9 16:13:21 IST 2009 >> > [ 0.000000] CPU: ARMv6-compatible processor [4117b363] revision 3 >> > (ARMv6TEJ), cr=00c5387f >> > [ 0.000000] CPU: VIPT nonaliasing data cache, VIPT nonaliasing >> > instruction cache >> > [ 0.000000] Machine: Freescale MX35ADS >> > [ 0.000000] Memory policy: ECC disabled, Data cache writeback >> > [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on. >> > Total pages: 32512 >> > [ 0.000000] Kernel command line: console=ttymxc0,115200 >> > root=/dev/ram initrd=0x80800000,16M ip=off nohlt >> > [ 0.000000] MXC GPIO hardware >> > [ 0.000000] MXC IRQ initialized >> > [ 0.000000] MX35ADS EXPIO(CPLD) hardware >> > [ 0.000000] PID hash table entries: 512 (order: 9, 2048 bytes) >> > [ 0.000000] Clock input source is 26000000 >> > [42949372.960000] Dentry cache hash table entries: 16384 (order: 4, 65536 bytes) >> > [42949372.960000] Inode-cache hash table entries: 8192 (order: 3, 32768 bytes) >> > [42949372.970000] Memory: 128MB = 128MB total >> > [42949372.970000] Memory: 110832KB available (2264K code, 180K data, 104K init) >> > [42949372.970000] Calibrating delay loop... 1556.48 BogoMIPS (lpj=7782400) >> > [42949373.200000] Mount-cache hash table entries: 512 >> > [42949373.200000] CPU: Testing write buffer coherency: ok >> > [42949373.210000] net_namespace: 288 bytes >> > [42949373.210000] NET: Registered protocol family 16 >> > [42949373.230000] checking if image is initramfs...it isn't (no cpio >> > magic); looks like an initrd >> > [42949378.430000] Freeing initrd memory: 16384K >> > [42949378.430000] JFFS2 version 2.2.
