Re: [ECOS] Re: fatfs help.

[David Brennan <eCos at brennanhome dot com>]

I honestly have not done much (any) troubleshooting on this yet. And I 
am on vacation this week, so I do not have access to the hardware. 
However, here are the answers to you questions.
1. No, I have not tried reading the CF in windows/Linux.
2. I have only played with the one CF so far and it was formatted MS-DOS 
6.22. (Or may have been pre-formatted, I actually don't remember now. I 
know it used to boot to MS-DOS 6.22.)
3. The code is from CVS. I saw your patches, but I figured I'd wait 
until someone decides to commit them before trying them out. Unless you 
think this may be the problem.
4. I don't have the code at home. I can provide a code sample next week.

Thanks for your advice. I was definitely planning on getting around to 
testing the more when I get back next week.

Thanks
David Brennan
