Seems chip 0x8033 doesn't follow specs definied by sdcard.org ?! I got the TI 0x803C by reading out driver details from a windows machine (HP Laptop) in a shopping mall :) > What's the current level?

I forgot the prefix "0x". the line now says: if (sc->firstBARat>0x05 || sc->slots>0x50) ... > The code should use more of the higher level interfaces in > FreeBSD for accessing the pci bus. Could you please give me hint on that ? I thought bus_space_* is already an abstraction of the PCI bus (guess, I realy have to walk through the pccard sources). > The code should stive to be more style(9) compliant. Its style is so > different from the usual as to be difficult to read. I printed out the man pages and had it as my bedtime lecture ;) The code has been now "styled" a bit. I'll later setup a web page with current codefile. for now the code is available at: http://www.sashi.de/downloads/freebsd/sdhci/sdhcidd-current.tbz Regards, Sashihome | help
