RE: [avr-gcc-list] in and out instructions

To answer my own question the SPMCSR is mapped to 0x37 for the in and out operations, 0x57 is the load store locations.

When attempting to do inline assembly I get the error message that the address needs to be less than 64 when attempting to use in and out instructions. Specifically I was copying this line of code from the At90CAN128 datasheet.

 

Out SPMCSR, r24

 

Note that SPMCSR on the at90can128 is address 0x0057 which is greater than 64. I was wondering if the instruction set changed or something on this part?

 

For further information I have not been able to get bootloader to work on this part, and was wondering if it was a problem with the sts instruction verse the out instruction.  As far as testing the bootloader I have tried the functions in the boot.h of the latest release of WINAVR, which is 8 months or so old now, and I know there are some bug fixes to the libc but I have not been able to find a new windows port of AVR libc.
