Hello.
Solution Dunker gave me, but the problem was in the same programmer. I used MKII isp, now programmed ATmega 64 UPA-USB and immediately appeared Hardware ID.
I greet and thank no__name.

Today i read flash for cas 3 xprog read it as 2048kb it should 512kb ,,any opinion please ?

This is normal for xprog. Rosfar on the other side read only 512k and is correct also. Xprog use the whole range of addresses for this mcu from 0 to 1FFFFF, despite the fact that only some blocks are used. The unused blocks are filled with FF. Rosfar use only the blocks that contains data hence only 512k is produced.

Thanx
And what if i need to write other flash with 512kb?

I made a script for upa to convert from one to the other format.

**ttzag** · 11th January, 2015, 09:56 PM

'write another one with 512kb', and by Xprog? If so, just use it the read 2048kb dump.

You will need to have upa 1.3 installed but no need to be plugged in. Load your dump in upa and use the script to convert your dump. The script has 2 choices, convert from rosfar to xprog or convert from xprog to rosfar, then you must save the converted dump. It is easy to use.

To prevent atmega brick do not touch JTAG and SPIEN fuses.
Also this firmware has bugs.
For example,if you got an MCU that hangs on bypass security,when you press cancel,the windows program is cancelled but the programmer is still doing bypass security.
To get it out of that bug,you need to disconnect it first,and reconnect again.
