I am not able to mount nfs, my Parameters are like following, it is from bootlin;
setenv bootargs 'console=ttyS0,115200 root=/dev/nfs rw
nfsroot=192.168.0.1:/nfs,nfsvers=3,tcp
ip=192.168.0.100:::::usb0 g_ether.dev_addr=f8:dc:7a:00:00:02
g_ether.host_addr=f8:dc:7a:00:00:01'
setenv bootcmd 'mmc dev 0; devnum=${mmcdev}; setenv devtype mmc;
mmc rescan; run loadimage; run findfdt; run mmcloados'
When I am on uboot console, I called ifconfig command on host, but I couldn't see the network interface. Is it normal?
How can I determine if the mac address is correct?
when I tried to ping, I get "host is not alive" feedback.
Bootlog looks like following;

I created a cfg file and added it to my kernel recipe, configuration is below. But I am still unable to achieve nfs mounting. Any suggestions?
Is there a way to make sure, may configuration changes are in the built kernel?
I have put all files, MLO, Uboot, dtb and zImage in Boot partition of the sdcard, is it correct?

I have taken rpi as a reference and trying to boot kernel to our custom board, modified the "dts" file by removing all peripherals except UART and Interrupt controller by changing the base address of the rpi board to our board specific address.
Seeting the env variables as follows,
$ setenv initrd 0xc3000000;setenv initrd_high 0xc4000000;setenv fdt_high 0xc1001000;setenv fdt_addr_r 0xc1000000
$ setenv bootargs earlyprintk console=ttyAMA0 mem=128M noinitrd root=/dev/mtdblock3 rw rootfstype=jffs2 rw init=/sbin/init
This is the error log we got....

Please help me,Thanks in advance.
Seems like the problem occured in interrupt context in procedure __vic_init. This procedure tried to access virtual address 48000fe0.
By the way - are you sure that this is complete calltrace taken from dmesg?
If this is only a snippet taken from dmesg - put the whole calltrace here.
If you have sources for this procedure __vic_init you can debug it - I mean find the number of the line in source file and do the further debug.
I'm running uClinux on a SmartFusion2 as part of a University team building a small cube satellite. However, I'm not super experienced in Linux kernel, and this issue has had me stumped for a few days. I'm trying to get the SmartFusion to run a program on bootup. Currently, the only .uImage that does this is the test 'hello' file. I'm trying to recreate the process for another program, but am running into some difficulties.
in my hello directory I have the following files: hello.busybox, hello.kernel.M2S, help.txt, hello.uImage, Makefile, hello.initramfs, hello (directory)
in the hello subdirectory (projects/hello/hello):
hello (executable), hello.c, hello.gdb, hello.h, hello.o, Makefile
to try and get the uImage to boot and run a different program, I made a copy of my projects/hello/hello directory and renamed it 'goodbye', with a few minor changes int the .h and .c files for testing purposes. Now I'm trying to get the executable 'hello' in projects/hello/goodbye to run on boot.
My initramfs file originally looked like this:
# This is a very simple, default initramfs
dir /dev 0755 0 0
nod /dev/console 0600 0 0 c 5 1
nod /dev/tty 0666 0 0 c 5 0

dir /proc 755 0 0
file /bin/hello ${INSTALL_ROOT}/projects/${SAMPLE}/hello/hello 755 0 0
slink /bin/init hello 777 0 0
I changed the last two lines of the initramfs to read as follows:
file /bin/hello ${INSTALL_ROOT}/projects/${SAMPLE}/hello/goodbye 755 0 0
slink /bin/init hello 777 0 0
But when I try and boot the SmartFusion2 after remaking the uImage, I get this, witht the error at the bottom:

Can somebody help explain why this is happening and what I need to do to my initramfs to make it run the proper program on boot? Thanks!!
As it turns out, I was confused about how those two lines worked. When I finally figured it out, they looked like this:
file /bin/hello ${INSTALL_ROOT}/projects/${SAMPLE}/goodbye/hello 755 0 0
slink /bin/init hello 777 0 0
then it worked as desired, and I was able to implement it into other uImages.
I am working on implementing SMP support in Linux kernel for Marvell PXA2128 ARM SoC. I am using Linus Torvald kernel as base kernel. Kernel version is 3.5. I have added SMP support in Linux kernel, I am able to boot with the second core but sometimes my kernel crashes with "Attempted to kill Init" message, that is, init process of initramfs dies somehow, don't know why. I thought L1 cache of second core is corrupted, so I invalidated the L1 cache of second core before it enters the Linux kernel execution. Crash log of kernel is like

Please give me a clue what important I am missing in SMP implementation.
I run an embedded linux-3.10.29 on a PowerPC board (big-endian). To debug my ethernet controller, I need to check some system registers. The SoC system registers lies at address 0xe0000000 (3584M). So I disabled CONFIG_STRICT_DEVMEM in linux config and ran:
$ dd if=/dev/mem of=/home/mem.dump bs=1024 count=1k skip=3584k
dd: /dev/mem: Bad address
This command should skip the first (3584k * 1024B =) 3584MB from /dev/mem and copy the leading (1k * 1024B =) 1MB to /home/mem.dump. I also tried to dump various 4kB ranges inside the overall 1MB, leading to the same issue.
This memory space is widely ioremapped by my kernel. Although I am not quite sure this is a problem.

I have an alternative called mem_util and #tangrs taught me that devmem provides the same functionality. But what is this bad address issue with dd?
[EDIT]
$ strace dd if=/dev/mem of=/home/mem.dump bs=1024 count=1k skip=3584k
