Hello satya ,

As i said the problem was in flash magic not with ISP.
As i said the flash gets programmed once and then not again and this has happened twice with two chips.
I am unable to find anything in the errata specifically for rd2bn , maybe i am looking at the wrong pdf , could u guys help me on that ? I have taken a debug file as suggested by esacademy the makers of flash magic and mailed to them , but no reply so far...
Do you think it is a board related problem as both chips failed identically during the second programming , quite a coincidence !!!

Kind regards
Thomas
