I messed up and had the wrong device selected while trying to load some code. This has resulted in my 90S8515 device going AWOL.
I have tried using the Parallel High Voltage programming and while this lets me erase the device, clear the lockbits, and enable SPI, the chip itself still doesn't seem to work properly.
After doing the above, I still can't get the STK500 to display any fuse settings for clocks and the like. In HV programming mode, the only fuses being shown are to enable SPI and short startup time. Selecting these options along with Mode 1 on the lockbits (no protection) still gives me errors when I try to use the normal SPI mode after a power-cycle and restarting the programmer. I'm guessing it is something to do with the various clock fuses being wrong, but I cant find anywhere to reset them as they don't display. I am using AVR Studio 4.10
Is there a way to restore the 90S8515 to the factory defaults using the STK500 ?
If so, any pointers or links to a How-To would be greatly appreciated.
