(...) Have you experimented at all with the compiler optimisation flags? I don't know if all of them are supported for the ARM architecture, and some options cause problems on other architectures, but there's a bit of a list here: (URL) removing (...)

(...) More precisely, I was told to increase the STARTOFUSERFLASH value if I increased the firmware size beyond the current value.

Hi, If I compile the LEGO firmware sources with gcc, the code size increases much beyond the 128 KB (which I think) the IAR compiled sources fits into. That means that one have to relocate part of the compiled code into the memory areas between (...) (18 years ago, 14-Mar-07, to lugnet.robotics.nxt.nxthacking)
