Hi David,

It is in fact identical. Disassembly with the tools found on
sourceforge
was fun, since they have endianness bugs, don't recognise the 'JMP'
which was the first instruction, and need each 3-byte instruction in
the
binary to be prefixed with a zero byte to make it 4 bytes. But after
sorting that out and going through it instruction by instruction, it
really does seem to match.
Heh. Amazing.
[ I think the code can be simplified: It currently copies itself to a
high program memory location, but this is not necessary because DSP
soft reset was never implemented (the reset would have been trapped by
the code, in order to load a new program). The driver instead power-
cycles the DSP every time a new program is loaded. ]
Thanks very much for digging it out.
No problem!
When you say 'GPL like the driver it came from', actually the driver
doesn't specify any version of the GPL but does refer to the top-level
COPYING file. So we'll take that to mean 'GPLv2 and not later', like
the
majority of the kernel. OK?
OK with me.
Thanks,
Fredrik
