Hi folks,

I've got AVR Studio 4.13 build 528, and a large pile of 90S2313 (and a few 90S1200) chips. The programmer is a USB ISPII.

Problem is, Studio won't let me select a 90S1200 or a 90S2313 in the 'Device' box for programming. There's a drop-down list, and neither are on it. With either of those plugged into the target system, it fails to even enter programming mode.

I change the ".include...def" line in the code (AVR assembler) to include a Tiny2313, plugged a Tiny2313 into the target system, no other change, and everything works flawlessly.

No other change, and I'm not using any feature of the tiny2313 that wasn't in the 1200. Incidentally, it compiles just fine with the 1200.def file included, but won't program the chip.

What can I do to make AVR Studio and my ISPII program the older chips?

Newer programmers don't support older chips ...by default..

I can't quite remember where but some twigging of an XML file will do the trick IIRC. Someone will know where, may need to wait or do a bit more searching on this forum.

Or just switch to using avrdude which can pretty much program every AVR through every type of programmer interface.

Hm. Okay, I'll try both those, looking for the XML and trying out 'avrdude'.

Thanks for your input,
