Nope, the 22pF cap is a filter cap to ground, not the DTR reset 0.1uF cap. Completely two different caps for two different purposes.
If you look at the lock fuse bits, 0x0F. This means that the bootloader section of flash is not readable with LPM and not writable with SPM. Yes, it will stick forever until you erase the flash.But again, this is only from a program access point of view. You still can access the bootloader externally via serial or parallel ISP programming.
BTW, did anyone notice that the OP solved his auto-reset problem with using a higher pullup resistor? So basically his auto-reset circuit wasn't pulling down RESET low enough to trigger a reset. See response #20.
Ah so... I do 0x3F, then 0x2F for unlock and lock, respectively. This is (if I figured the bits correctly) locking the bootloader area from writing or corruption, but allowing it to be seen (i.e. read). Correct?
To me, that means "series cap is too small" (or out of spec). Agree?
