cp error: can't open source file

new to QNX - trying to create a boot floppy.
Research says to copy Dev, Dev.con, etc - but when I try - I get the “can’t open source file” error.
Tried with -f, as Dev is a link to Dev32, etc - but still I get the error.

This is a new 4.25 install, and I’m logged in a root.


Post your exact command. Did you specify the full path of “Dev”, “Dev.con”, etc as the source file?
