Dear Ijaz and Farshid, thanks for your replies. I am now going thru the link given by Ijaz, quite a lot of posts there!
I did the bread-boarding method today(Sunday!!). Same thing resulted: AVR gets programmed(as expected), but the S52 doesnt. I also made another PCB, with some diagnostic LEDs, and it is pretty clear that Data from MISO dont reach PC. Shall I put more buffers in parallel? And, Farshid, I dont have access to any of 74244 derivatives, but 74HC244. I would post the pictures tomorrow. Regards, Vignesh |
