I was wondering if anyone had any experiences they can share about using XIP on ucLinux? As far as I can see it is supported for the bootloader, the kernel and also for applications, if the toolchain supports this. My question though is if anyone has done any studies on how much memory is really saved doing XIP. Instead of copying executables to RAM, just .data and .bss sections of programs are copied to RAM. Also, boot time is usually reduced when using XIP. However, I'm quite keen to hear about some practical examples on this and some real numbers on what is exactly saved. Can anyone provide more information on this? I could not find any resources online.
Thanks for any pointers.
