It says “Calculating requirements and dependencies” however it is not progressing…For once, (after half an hour) it achieved to finish progressing, however, this time I could’t see Embedded Debug extension in debug tool…
I went through forum and I couldn’t see any title about this problem… I’ll be happy to hear if you have any solution for this. I am a real beginner…

Warn : Unable to open FTDI Device tried: 'Amontec JTAGkey' and 'Amontec JTAGkey A'
Error: unable to open ftdi device: 2
Runtime error, file "command.c", line 456:
Does anyone knows what I should do at this point ?
Note: I am sorry for my basic questions. As I’ve told, I’m a new beginner in ARM technologies.
What is your JTAG type? It’s Amontec, oocdlink, turtelizer, etc.?
Because, from what I know, every type of JTAG has it’s own configuration.
It’s about the interface, device name, speed, vidpid, etc. in the configuration file. You should checked it before you ‘call’ the jtagkey.cfg in your command prompt.
And from the error have shown, it cann’t open a right device. So maybe the deice name in the configuration file is not correct. You can also see the OpenOCD doc. to know the config. phew…
Well, as far as I understood, I shouldn’t use Openocd…cuz my JTAG is JLink…
Let me tell you what I understood. I am using SEGGER JLink GDB Server to check my JLink is connected or not. Then, I am starting Eclipse and I am making the configurations as shown in James Lynch’s tutorials (I am using Yagarto compiler and I installed Zylin CDT plugin)
However when it comes to config part…I don’t know what to do…cuz I don’t know what to write to commands window…It is AT91SAM9260-EK and the configuration should be different…I think…
Am I on the right way ? I don’t have neither solution for this problem nor any feedback…I am so lost…I am doing my internship in a company…and they want me to be able to program that evaluation kit…I programmed microcontrollers before and used eclipse…However this is something different for me…
I need help !?! Any of you have any suggestions ???
It is working !! I found some useful stuff on forums and now I can debug my AT91SAM9260-EK board bu using Eclipse + SEGGER JLink GDB Server + YAGARTO Compiler
After building project and installing Zylin CDT plugin, in the debug configuration window of Eclipse, I’ve used the following codes which I found in forums:
In Commands tab, for the ‘Initialize’ commands part:
target remote localhost:2331
and in ‘Run’ commands part:

so apparently, I have used the .gdb part (which was existing in my project file that I’ve downloaded) in the ‘Run’ commands part.However, there is a little problem that I can’t configure the master clock, so I just didn’t inlude the following part in ‘Run’ commands part:
# Configure master clock
echo Configuring the master clock...\n
# Enable main oscillator
set *0xFFFFFC20 = 0x00004001
while ((*0xFFFFFC68 & 0x1) == 0)
