i am new to embedded programming, so please be easy on me...
i designed a circuit board, got it printed, and used the AT90S8515 as m MCU. ive soldered the MCU, programming pins, and all of the other littl stuff on to see if it will program.
i am using the ATAVRISP MKII programmer, and AVR studio reports that i can communicate with the chip.
here is my problem: the Mode 3 lock bit is enabled (further programmin and verification disabled) and i have no idea how to fix that. th preserve EEPROM fuse is also set. the MCU came like this (i bought 10 they were sealed in the cut-tape, but they must have been shipped fro atmel like this)...
how do i get unlock this chip so i can write a program on it? ive got som test LEDs connected to the MCU and i started this project to teach myself.
last thing. the SPIEN fuse is ghosted out with a little red thing in th corner of the box and it is unchecked (Set to 0 i assume). is this how want it?
thanks a TON for anything you guys can help me with. im stuck and feelin pretty bad about this project since i could have potentially wasted a lo of time and money if the MCUs i bought aren't going to be programmable.
