Hi
I am newbie on RedBoot. I am using redboot on an intel board.
I am [trying] to load and run a RAM image, since I do not want to mess
up the currently [runnable] image that is on the rom memory and is
working.
But the image I got from intel and the image I built from the sources
are showing up some trash on the console when i execute them
[for instance: $T0a0f:0c002000;0d:ec0ffd03;#39]. This pattern goes on
an on for each key I press.
I am loading the file redboot_RAM.srec [load -v -r -m xmodem -b
0x00200000 redboot_RAM.srec] [I also tried via tftp, same result...]
and shooting "go" ro make it run, but all the time I get this output.
Would any know what might be wrong ? I'd guess I am executing a some
memory position that has nothing there ... But I do not know how to go
on. Any help would be really appreciated.
I also tryed "go redboot_RAM.srec" but it did not work either...
The options you are using for the download is causing the problem.
Try this:
RedBoot> lo -m xm redboot_RAM.srec
RedBoot> go
Your options do two things wrong:
-r: downloads the image raw, which means you've loaded ASCII S-records
into memory - these are not executable instructions
-b: eCos programs are not relocatable, hence they must be loaded at
their native address. 0x200000 is probably not the correct address.
