Honored Contributorok, but any data sections that would normally be initialised by a bootcopier will be incorrect?
I don't have anything in my code like static variables initialised, but if the library has or the irq_handlers or other altera bits then they'll not be happy! I will use an internal ROM, but I'd really like to be able to use a RAM and be able to use it for scratchpad memory after bootup! But, in order to acheive that I'd need to be able to get the reset input not to just reset the nios,etc but to actually reset the FPGA and force a boot/bitstream download - something which I'm not sure can be done internally? Externally I guess its only a matter of pulling nCONFIG low - but it would be great to be able to do that internally with no re-spin of PCB!!! Thanks for the help!
