Thanks a lot for your suggestion.
I will once again try to put all the information as you suggested.
** What does pxa.cfg contain?**
PXA.cfg file contains the openoncd configuration files. Basically, this file
contains the information about telnet ports and the interface like JTAGKey2,
olimex-arm-usb-ocd-h configuration file.
**How do you select between JTAGkey and ARM-USB-OCD-H?**
The interface between JTAGKey2/ARM-USB-OCD-H and the target devices through
USB. At a time I am using one device to communicate to PXA270.
**What is the full debug log (-d) of openocd in a successful case using the
JTAGkey?**
Step by step procedure to execute openocd command:
1.Open cmd prompt and change the directory to openocd
2. execute openocd -f pxa.cfg, target state will come to halt.
3. open another command prompt and telnet to localhost using the command:
telnet localhost 3333
4. open onchip debugger will open and then issue the command: **flash
write_image erase unlock c:/pxa.nb0**
5. Writing to flash starts and compeltes writing file from c:/pxa.nb0.
**What is the full debug log when it fails, using the ARM-USB-OCD-H?**
Step by step procedure to execute openocd command:
1.Open cmd prompt and change the directory to Openocd_olimex
2. execute openocd -f pxa.cfg, target state will come to halt.
3. open another command prompt and telnet to localhost using the command:
telnet localhost 3333
4. open onchip debugger will open and then issue the command: **flash
write_image erase unlock c:/pxa.nb0**
5. Writing to flash starts and compeltes writing file from c:/pxa.nb0.
I also attached necessary configuration files which are used for programming
PXA270.
Please let me know if you need any further information.

Dear All,
I am very new to the family of open On-chip debugger. I need your help and
support to use OCD products which are required for my project.
I would like to explain about the openocd debugger or programmer I am using in
our project and need your valueable inputs.
* I am using Amontec JTAGkey2 programmer to program PXA and CPLD. It is working
absolutely fine without any issues.
* Since I am having only one Amontec device and there is no support available,
I found Olimex ARM-USB-OCD-H as an alternative device and started working on it.
* I verified pin confifuration between the two devices are almost the same
except pin2 in Olimex device has Vref.
* Issues I am facing with Olimex programmer:
1. When I execute the command: **openocd.exe -f pxa.cfg** following
warning and error I'm getting
* Warn : Bad value '00' captured during DR or IR scan:
Warn : check_value: 0x02
Warn : check_mask: 0x07
Error: JTAG error while writing DCSR
2. Next step is to telnet to the localhost 3333 and then typed the command
: **flash write_image erase unlock c:/pxa.nb0 **, for PXA porgramming.
* I am unable to flash PXA programming and the error message I am
getting is: Failed to receiving data
from debug handler after 1000 attempts
Execution of flash algorythm failed. Can't fall back. Please report.
error writing to flash at address 0x00000000 at offset 0x00000000
I have attached the sceenshots for the reference.
Using Amontec device PXA programming and CPLD programming writing smoothly
without any issues.
But why I am facing issues using Olimex ARM-USB-OCD-H programmer. Your kind
support is much appreciated.
Thanks and regards,
Madhusdhan H K
