I have similar issue as here(AVRISPmkII connection status: Unknown status 0x00) but different setup and changing bitcklock didn't help.
The current setup is atmega328p with external oscillator 16MHz connected to ISP interface of avrisp mkII programmer but whatever I do It keeps on showing the same output all the time:

avrdude done. Thank you.
Any help is appreciated!
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

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/ttyS4 0666 0 0 c 4 68
nod /dev/ttyS5 0666 0 0 c 4 69

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 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.

The boot parameter "lapic" is added by modifying /boot/grub/grub.cfg:

}
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?

I install ubuntu 16.10 64bit in my PC and run perf record -b successfully. I think maybe it's wrong in kernel or linux-tools-4.2.0-27-generic or linux-cloud-tools-4.2.0-27-generic package.
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:

Good luck!
I am using ReadFile to read a null character '0x00', but it is not able to see it.
If I send "0x01 0x02 0x00 0x03" to my program. It will receive "0x01 0x02 0x03". I know for a fact that my sending side is sending the null character (I used a scope to see the data).
I have checked the DCB structure and have fNull set to false. (which is supposed to allow for null bytes to be received and not discarded)
This is the configuration of the DCB shown from GetCommState:
DCBlength 28
BaudRate 9600
fBinary 1
fParity 0
fOutxCtsFlow 0
fOutxDsrFlow 0
fDtrControl 0
fDsrSensitivity 0
fTXContinueOnXoff 0
fOutX 1
fInX 1
fErrorChar 0
fNull 0
fRtsControl 0
fAbortOnError 0
fDummy2 0
wReserved 0
XonLim 2048
XoffLim 512
ByteSize 7
Parity 0
StopBits 2
XonChar 0 '\0'
XoffChar 0 '\0'
ErrorChar 0 '\0'
EofChar 0 '\0'
EvtChar 0 '\0'
wReserved1 0
Am I missing something in the structure that might be blocking the null character as well? or is it possible it's a driver configuration or registry configuration that I need to change?
You have XON/XOFF flow control enabled and have specified null as the XON/XOFF characters. That is why you are not seeing null data bytes. You need to set the fOutX and fInX fields to 0 instead of 1.
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..
