X-SW-Source: 2005-07/txt/msg00233.txt.bz2 Hi, I am interested in a AT91RM9200 Port of ecos & redboot. (I know that there = is a port from ecoscentric, but I am interested in a free one.) I have searched the mailinglist archive of ecos-discuss for AT91RM9200. Status: I have found an old porting effort from 2003 http://sourceware.org/ml/ecos-discuss/2003-11/msg00416.html What is the status of that port ? I have found a new porting effort at http://sourceware.org/ml/ecos-discuss/2005-06/msg00263.html What is the status of that port ? Beyond that I have found several people who are (or were) interested in such a port. I have CCed this mail to them. What I have done so far: I am an experienced programmer but relatively new to both ARM and eCos. I have spent some time reading manuals (ecos, at91rm9200, gcc, ...) + sources and searching the web. I have a lomx arm board (http://www.lomx.net/en/lom_arm9_project.htm). I successfully compiled the atmel-bootloader (gcc version) from http://www.teest.com/at91/romboot.tar.gz (with minor modifications) with the gcc from http://ecos.sourceware.org/getstart.html. I could download and run it via xmodem (minicom & http://www.koansoftware.com/en/art.php?art=3D68 ). What I want: Currently I would be content with redboot booting from spi dataflash and talking to ethernet, no mmu required. I would like to participate in porting redboot/ecos to at91rm9200. How can I help ? Is there anything (incomplete) I can test or use ? BTW: There was an "MMU question - AT91RM9200" some time ago. An advice said one should map RAM to virtual address 0x0. There are two options for this: You can map SDRAM or internal SRAM to 0x0 (or external SRAM). The "default"= is internal SRAM, so the big SDRAM can be mapped somewhere else (e.g. 1-to-1 logical to physical map should be possible).
