please advice nir
for ISP-Flashing with AtmelWM WinISP"
1) WinISP is not an Atmel product, it is a discontinued Philips (NXP) product.
2) I have (fortunately) no idea about Arghmel, but with NXP you sometimes "get through" by lowering the baudrate.
3) if you are using a USB to RS-232 converter that, most likely, is your problem.

hi, i'm not using any converters, direct cable rs232 that worked with atmel eval board.
and about the Application Note 156: http://www.keil.com/appnotes/docs/apnt_156.asp "This application note shows how to modify the Keil MCB251 (MCBx51) Evaluation Board so that you can use the WinISP FLASH programming utility from Atmel Wireless and Microcontrollers."
i'm guessing it means FLIP, i'm using the FLIP 3.3.4
