This happens if you try to load the ELF file to somewhere other than RAM. elf loading goes through HTIF and writes to the sim's bus device. There must be a writable device at this location on the bus.

...At least that's the behavior a now, a year and a day after you posted this. I thought I'd post the explanation so other people could find the reason why this happens.

Make sure that the elf _entry symbol has a corresponding RAM in spike, and that it's big enough to hold the code and other data you're loading.

@evancox10 I still have this as my project, it's just conservated for now.
I'm sure I can use that info later, thank you

@alexmechanic Have you solved this issue? if you did, could you please tell me how to do, since i also encounter this issue, Thanks a lot.

If Spike does not find a device or MMU to which this address could correspond to, you will get this error.
Having said that, can you share what address you are trying to write to?
And if you have any additional devices attached in Spike?

Sorry, currently I left working with this project and cannot force this issue anymore.
