Hi,
In the Arduino UNO board i tried loading the program using ISP programmer by using the default fuse bits settings ie: Fuse Low = 0x62, Fuse High = 0xD9, Extended = 0xFF . While programming with this default fuse bits it was showing Chip Enable Program Error. Is there any problem with the fuse bits that has been set in progISP.?
If you use an external programmer to load code onto your Arduino then it will have overwritten the bootloader and you won't be able to upload via USB. You can easily reupload the bootloader- just connect your programmer, select the board type and use Tools>Burn Bootloader.
These default fuses are the factory defaults. They are not the default fuse values of the Arduino Uno. You have set your chip to run at 1 MHz on the internal clock, whereas the Uno usually runs on the external 16 MHz resonator. I don't know why that would cause the "Chip Enable Program Error" because I have no experience with this progISP thing. Which ISP programmer are you using?
I have seen this same thing come up multiple times lately. Why did you want to use progISP?
