(Top posting to conform to OP. Eww.)
There are certain features which you can count on being in a processor,
but can't always easily figure out where or in what form. The silicon
revision register is one of them, at least these days.

OK, found it.
It is the DSPID register at 0xffe05000...
Best,

Hi all,
thanks for the hints, though I didn't find anything yet.
Have searched hw and reference manuals, app notes, rom source code.
BTW, it looks as if there are limitations on reading the boot rom area,
at least my homegrown serial dump tool crashes the DSP when I try.
Best,
Andre

Which you can find by reading the fine manual. It should be buried
somewhere in a data sheet or user's guide or something.

IIRC there is location in the bootrom area containing revision information.

Dear all,
maybe this is a homework issue, but I didn't find it in help on on the web:
Is anybody aware of a method to detect the silicon revision of ADI
blackfin at runtime? The JTAG interface obvously can, so could my firmware?
Best regards,
Andre
