Hi Eric, thanks for the datalogger link, lots of useful info re: SD on there! From the comments I gather you had the same problem where 1/4 bit data path made no difference… and it looks like there are some other driver inefficiencies and so forth… but I would expect that a processor with a specific SDHC interface (as opposed to simple SPI) should attain respectable write speeds. Still because of time, I used ChaN's FATFS library to handle files. The errors may come from gmake or more commonly from one of the build tools: compiler, linker or XDCtools.
