Re: [ECOS] arm-elf & ecos

["Mike A" <embeddedeng at hotmail dot com>]

Hi Andrew,

I am not very familiar with unix. The ecos source (got through WinCVS) is 
for dos file system, so my guess is it would have the line feed character 
following the \. Assuming this, what should be the mount configuration best 
suited for this? text or binary?


Let me know how I can switch between modes. And do I have to build the tool 
chain (arm-elf) again after switching to a different mode.

Thanks,
-Mike.
