Hello,
In a few words: what is the device to be used for a ROMFS root ?
More: I configured ELKS as a ROM image for an embedded system, and I run
it under EMU86, but I cannot figure out:
1- how to tell ELKS to read the ROMFS superblock from ROM address space?
2- how to build a ROMFS image to put in the ROM address space?
All my tries end up with the well known:
$ ./emu86 -w 0xe0000 -f ../../elks/elks/arch/i86/Image -x 0xe000:0x42 -i
$ ./pcat `cat emu86.pts`
