> @anjiahao1 already add ELF XIP last year, but deploy only on ROMFS and LROFS (Lightweight Read-Optimized writable FS): https://github.com/open-vela/nuttx/tree/dev/fs/lrofs lrofs has the same idea as xipfs, but lrofs disk layout is binary compatible with ROMFS. I didn't know about that repo, I could have used LROFS then. I will investigate and compare. @anjiahao1 can you run multiple (independent) instances of the same ELF PIC module (with XIP) in a no-MMU system? Do they share .text, but have separate .data? > > Let wait you comparing the difference between FDPIC ELF and XIP ELF. If standard ELF PIC works with XIP on non-MMU systems, then I think we don't need FDPIC ELF. The code is done already so I will open the PR soon. > OK, it's fine to merge this pr first, and work on XIP ELF and FDPIC ELF next.
