I just got email from Atmel verifying that the two instruction sequence for
updating SP is correct.

I have code that calculates the CRC of Flash at power up, that works
fine on the AT90CAN64 part.
When I move the CRC function to the Tiny88 it does not work.
To me it looks like in the generated code _data_load_end is stuck at
0x0100 (256),
but the map and symbol file show reasonable values:

Because there is a rather arcane way to represent characters in which
three question marks appear prominently. I recall now that it's

I have made good experience using the fact that the compiler
concatenates sub-strings. Just dumping examples from existing code:
static char e_origin[] PROGMEM =
"\x1b""AT\x00\x00\x14\x12\x01\x00""C\x7F\x00" ;
This example also illustrates one problem and its solution: the compiler

The expression is probably not 'too complex for the compiler' but too
complex for the programmer.
Your intention was probably not
if (pgm_read_byte((PGM_P)(TESTIMAGE + (IMAGE_SIZE * projnum) + SIGNATURE) != 0))
but
if (pgm_read_byte((PGM_P)(TESTIMAGE + (IMAGE_SIZE * projnum) + SIGNATURE)) != 0)
