avr-gcc: What names for the address spaces?
Do you plan to introduce pure 24-bit pointers pointing into FLASH or SRAM? IMHO a mixed pointer is very slow, because you need to check some bits everytime you plan to access...

Fixed point library fro AVR-GCC?
geckosenator: You are doing a great job, so don’t give up. As I can see the Atmel toolchain has implemented your path, and support fixed point math.

XMEGA, can UART override pin configuration
I suppose so, thanks for help. I studied diagrams in Atmel’s notes, and it look like the peripheral (UART) only gives data to GPIO OUT, but the output circuit is still...

avr-gcc 4.6.1 and Link Time Optimization on Windows
It’s a pity that Atmel don’t support avr-gcc active development (at least the support is not very big), instead of they produce a messy toolchain and completely crazy AS5. It...

avr-gcc 4.6.1 and Link Time Optimization on Windows
So it is interesting to calculate how often R1 is reloaded in real application because of mul – so it will give us an idea if the effort you mentioned, is balanced by some space...

avr-gcc 4.6.1 and Link Time Optimization on Windows
If we are talking about code size – why not to change ABI, and move zero_reg (R1) to some other register, e.g. R2? The problem is with newer AVRs, which have mul instruction...

C++ and section attribute
Ok, finally I’ve found a solution – not perfect, but working. I link everything like in description above, but main app has moved data segment beyond addresses occupied by...

C++ and section attribute
Ok, I can see that data sections containing static members must be relocated too, otherwise static members are overlaping global and static variables of main app. Or is there any...

Thanks skeeve, I’ve learnt a lot. My first tests have shown that your solution works fine, and moreover I don’t need to define additional sections. I will show what I’ve...

Every advice is appreciated, especially yours. But please focus on the main problem, the name of the section is not important. But because I must link the app with bootloader code...
