You could consider using John Calixto's CMD passthrough ioctl for this, and writing your tests in userspace: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=cb87ea28ed9e75a41eb456bfcb547b4e6f10e750 It would be great to include your finished tool in a testsuite, both for testing card commands and for testing the ioctl functionality itself. :) Thanks! - Chris. -- Chris Ball <cjb@xxxxxxxxxx> <http://printf.net/> One Laptop Per Child -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
