Hi Tomek,
That did the trick! I should have checked it earlier before shouting
here :( RnW interface_signal was missing in config file. I am not
entirely sure of its purpose though?
------------
Debug: 188 148 signal.c:42 oocd_interface_signal_find(): Interface
signal - searching for 'RnW' signal...
Debug: 189 148 signal.c:50 oocd_interface_signal_find(): Interface
signal - not defined (yet?).
Error: 190 148 ft2232.c:679 ft2232_bitbang(): Requested signal not found
on this interface!
------------
Couple of more questions:
1. Output is too verbose, is there an easy way to disable it? This
affect image load operation.
21708 bytes written at address 0x00100000
176 bytes written at address 0x20000000
downloaded 21884 bytes in 87.741547s (0.244 KiB/s)
^^^^^^^^^^^
2. Subsequent run of openocd results in following:
Debug: 289 223 swd_libswd.c:295 libswd_drv_mosi_8(): OpenOCD's

I have to manually reset the target for this.
Thanks a lot for help!
Thanks,
Mahavir
