 +Problem: My ATtiny4/​5/​9/​10 reads out fine, but any attempt to program it (through TPI) fails. Instead, the memory retains the old contents.

 + ​Solution:​ Mind the limited programming supply voltage range of these devices.
 + ​In-circuit programming through TPI is only guaranteed by the datasheet at Vcc = 5 V.</​code>​
 +
 +STK 600 also supports TPI
