I will, but I have to have a contingency plan for what happens once products have been in the field for a while and the RedBoot that's in ROM is no longer compatible (or a bug is found) and can't be used with newer eCos applications. > > How do the output routines in RedBoot decide whether to > > packetize output? > > It all happens, almost by magic, depending on what's been > registered. And I have to be able to emulate that magic in my HAL output routines when I get to the point where I can't use RedBoot due to a bug or compatibility issue. -- Grant Edwards grante@visi.com
