The IDE interface in eCos does work quite well. But there are a couple
of items to look at.
- Do you have the current version of the IDE code because there was a
bug fix a few months ago concerning the reading and writing of a block
of data from the IDE drive?
- Is the hard drive partition that you are trying to read formatted as a
fat32 filesystem?
I have not used the eCos test software so I don't know if it is OK. You
might want to insure that debugging output is enable for the drives and
file system. Hopefully, that will give you more information about what
is happening.
Have a great day,
Don
