Can't flash with avrisp mkII in avrdude Version 6.0.1 - linux

I have had problems with this programming board. It is set up correctly seems to be an AVRISP MKII.
I received the following error messages upon flashing with avrdude:

It is hard to identify the issue since my version of the programming board doesn't have such great documentation.
Thanks in advance!

This bug was causing the problems. I simply reverted to the previous version of avrdude (5.11.1) and it worked. By now there is an even newer version of avrdude (6.3), this bug might no longer be a problem in latest version.
Here are some steps:
Revert to an older version of avrdude either by using sudo apt-get install <package-name>=<package-version-number> OR sudo apt-get install <package-name>=<package-version-number>
Check if it works: avrdude -p <your part name> -c <your programmer name (avrispmkII)>
You might have to specify a port. Use something like ''watch ls /dev/tty*'' to find your device if you get an error like this one:
(trusty)chandran#localhost:~$ avrdude -c avrispmkII -p t85
avrdude: ser_open(): can't open device "/dev/ttyS0": No such file or directory
avrdude done. Thank you.
Here is what it will look like when you get it right:
(trusty)chandran#localhost:~$ avrdude -c avrispmkII -p t85 -P usb -vv

Run program on boot with initramfs

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
nod /dev/null 0600 0 0 c 1 3
nod /dev/mem 0600 0 0 c 1 1
nod /dev/kmem 0600 0 0 c 1 2
nod /dev/zero 0600 0 0 c 1 5

nod /dev/ttyS2 0666 0 0 c 4 66
nod /dev/ttyS3 0666 0 0 c 4 67
nod /dev/ttyS4 0666 0 0 c 4 68
nod /dev/ttyS5 0666 0 0 c 4 69
dir /bin 755 0 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.

how to enable linux perf tool's branch sampling

I use linux perf tool to collect branch info of programs, and the command and result is as follow:
$ sudo perf record -b /bin/ls
Error:
No hardware sampling interrupt available.
No APIC? If so then you can boot the kernel with the "lapic" boot parameter to force-enable it.

power management:
apic and bts in flags entry is strengthened(I want but just encapsuled by "**") and I don't know what else is import for this case. And the other 7 processors are same to processor 0.
The boot parameter "lapic" is added by modifying /boot/grub/grub.cfg:
menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-0ed8a872-4eb7-4339-a0bb-6c0033da582e' {

initrd /initrd.img-4.2.0-42-generic
}
just add lapic in linux entry.
But no sense after rebooting.
My questions:
1) What does the error info means?
2) Does the perf tool branch sampling use Intel Branch Trace Store(BTS)? Or Last Branch Record(LBR)?
3) How can I look up the LBR support?
4) what is different of the LBR and BTS support between x86 32bit and 64bit?

Problem resolved! Don't remember what was the reason exactly. I guess clock crystal didn't have proper connections on a breadboard. So, I would say:
Check your wiring

Kernel Panic after SMP Implementation - Attempted to kill init

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

Cannot connect to the usb-serial port (GSM modem)

I've decided to bring up a GSM Modem for my Linux machine (OpenSuse 12.1 64-bit on Vmware) so that I can use it as the SMS gateway. I've got a Wavecom M1306B GSM modem which provides a USB interface, and obviously there is a USB cable (end to end, GSM Modem to my Desktop) with it.
I tested this modem successfully with my Windows 7 64-bit PC by running some basic commands on it. (like: AT , ATZ, ..)
Here are some of my logs:

I noticed that the Baud rate of USB0 interface is too much, so i tried to assign 115200 :
machine2:/proc # setserial /dev/ttyUSB0 baud_base 115200
Cannot set serial info: Invalid argument
So, it is the problem ... and I receive this error.
Whenever I try to connect S0, S1, USB0 interfaces via minicom, it simply doesn't work.
Baud_base is not the port speed, it's the maximum speed when a frequency divisor is 1. The ability to set baud_base probably doesn't apply to USB serial device at all, and it's most certainly not what you want.
Use stty to set the port speed, or use cu or minicom for testing (they can set port speed by themselves).
I'm not sure about the baud rate but If you open up another terminal and do cat /dev/ttyUSB0
Then in the first terminal do echo AT > /dev/ttyUSB0 you might get an OK back..not sure if it helps but it should get you a response at least..
