It is currently work in progress in eCos, but as yet uncommitted (far more info and history than you need to know is here: ). Most development is taking place on a Freescale Kinetis board, primarily by Ilija Kocho, with me interfering along the way ;-). The eCos changes still need to be reviewed before they're committed. STM32F4 is likely to follow very soon after. Ironically, it's not likely to be committed until we have some confidence that what goes into GDB will match up with what the stub is doing! We wouldn't want to commit something that has to change in an incompatible way. Jifl -- eCosCentric Limited http://www.eCosCentric.com/ The eCos experts Barnwell House, Barnwell Drive, Cambridge, UK.
