Hello Carlos,

Porting eCos to that board is going to be very, very hard. Please check the
archives from this week and last: someone from Italy already tried to
modify the eCos installation on the XF55 couldn't do it because 1) Falcom
won't help you modify the eCos installation on it and 2) Falcom has not
released the source back to the community.

I just searched my own archive and the sources.redhat and found some info regarding the board. In the docs of their eval board, at least in the website, they say that it now supports ecos 2.0 and they even seem to have some source code allowing developers to use different firmwares.

From what I understood, they accept a TCP/IP stack, ecos 2.0 and two other
proprietary firmwares.

Finally, it'll be extremely difficult to do your own port because the
processor on the XF55 is the ARM7TDMI embedded in the GPS' SiRFStar II
chipset... and SiRF does not release any technical details on their chipset
without a several thousand dollar development kit and an NDA which will may
prevent you from releasing any source written for it back to the community.

My main objective is to: ** track my position using GPS ** send it through GSM+GPRS and do some sort of GET or POST ** sleep for some time(hours/days) ** consume as little as possible

Good luck,

Andrew

Assuming that the port is already done but they don't release the source, only a binary to link. Can this be done? Are are my options in terms of other boards? Anyone?

As far as I know they sell their eval kit together with a eCos SDK, examples showing how to access and use GPS, GSM and GPRS functions and maybe some versions of FALCOM firmware (FALCOM and SiRF firmware without sources). I think eCos should run "out of the box" (including RedBoot) on a XF55. Data sheets (current consumption etc.) and manuals should be available on their website. Perhaps you should check if their firmware fulfills all your needs.
