- Subject: RE: [ECOS] Capacity problem?
I short clarification that i missed in the first email:
When starting from flash then i copy all code to RAM and resume
execution there. By doing this i can startup an image almost everywhere
in the memory and then make it copy itself to RAM 0x0->.
Since i execute in RAM (even with flash startup) then i don't have any
problems due to slow execution but maybe my CPU needs a special setup
when executing from flash??

Yepp, i changed from 4 to 16 a while back.
Is there anyone that has changed the startup files (vectors.S or the
board specific file like mbx.S) to setup some special registers ?? Maybe
i have missed some....?
Any other ideas?
Regards, Daniel
