Hi

I'm new to the Nios processor and I'm trying to understand the workings of the boot process.

If I understand you correctly, then this is very interesting information...

So - if I have a situation where there is an internal ROM containing a bootloader that can receive an application from an external device (port or other memory) to be run from SDRAM... then the easiest way to prepare the application to download or load, is to add ALT_NO_BOOTLOADER to the system library compiler preprocessor definitions and then use objcopy to move the .entry to a more useful place than the reset vector address... ?

Could you please give an example of the commandline used to do this relocation of the .entry section!

Thanks in advance
