RSteger and all,
If you go to the S08JM product page and select the "documentation" tab, then scroll down to the app notes, the DRM104 app note has the DRM104SW.zip right under it. Is this the firmware you wanted?
I've seen DRM104 links on other pages with the corresponding software link NOT on the page. This is the only page I've seen with both.... had to remember where the heck it was and how to get there.
I used the base SPI routines from the DRM104 software as examples to modify some SD card apps for 9S12xx to get an SD card working with a 9S08QE32 with FatFS. But the DRM104 doesn't do the whole FAT file system -- it just handles a few simple SCSI commands/responses between the PC and the SD card -- read a sector, write a sector, device status. The PC really does all the work.... cheaters! Now getting FatFS shoehorned into a QE32 -- THAT was quite a trick with only 2k of RAM!
Anyway, the DRM104SW code is not too bad. You should have no problem getting your SD card going with it.
