Re: [avrdude-dev] avrdude problem with Attiny13 - works fine in AVRstudio

[Haberler Michael]

I eventually figured out that the Kee Electronics JTAGICE mkII clone  
fails to implement CMD_SPI_MULTI properly. JTAG programming works fine  
with avrdude.

AVRISP commands as per AVR069 and used by Avrstudio work fine.

I'v sent a lengthy bug report to Kee aksing them to fix this.
