I unchecked all Cksel boxes. I understand this is opposite to ponyprog? The case is i get now unknown device, i suppose in this config i have set to ext clock source?

I understand this is opposite to ponyprog?
The case is i get now unknown device, i suppose in this config i have set to ext clock source?

I am using SPI dongle. But I want to change baud rate to a value less than 100bits/sec. Is it possible? how? what is the minimum baud rate that can be achieved? how to change the baud rate of programming Atmega16 using ponyprog. I am using SPI dongle. But I want to change baud rate to a value less than 100bits/sec.

If it tolerates 5V input, then there should not be a problem. If not, then you should scale dowt the signal from AVR to SRAM. You can use a transistor key powered from 3.3V or 3.3V buffer IC. You can go more rude by using a simple resistor voltage divider. You should read SRAM datasheet to find out if it tolerates 5V signal. If it tolerates 5V input, then there should not be a problem.
