Does it have an option to slow the programmer
down?
The ISP may need to be slower to allow for the clk
div, rather than the ext clock being selected as the STK200 does in fact have
the ext clock and ext crystal and won't have a problem getting back in, which is
not possible on the STK500 kits ;)
Do you have the latest Kanda AVRISP software or are you using Linux.

I'm using sp12 and avrdude with a stk200 for writing fuse bits to a
ATTINY2313. I have 2 dead uCs. I tried to write lfuse = 0xe0 for using
external clock source and avrdude showed an error. After this I all
the fuses are set to 0xff. Of course I cannot program or write new
fuse bits anymore.Is there any way to fix this or I have to buy a new one?
here is the dump from sp12:
11111111 are the fuse bits read from an ATtiny2313
0xxxxxxx - CKDIV8 - divide clock by 8 (page 22)
x0xxxxxx - CKOUT output clock on pin D2
xxSUxxxx - start-up time (datasheet page 24)
xxxxCKSE - CKSEL (datasheet page 22-24)
11111111 are the high fuse bits read from an ATtiny2313
0xxxxxxx - debugWire enabled
x0xxxxxx - EEPROM preserved in chip erase
xx0xxxxx - serial programming enabled
xxx0xxxx - WDT always on (page 41)
xxxxBODx - BODLEVEL (page 34)
xxxxxxx1 - reset-pin enabled (page 52)
thanks in advance !
