--- Comment #21 from Gary Jennejohn <gljennj...@gmail.com> --- (In reply to Alexey Dokuchaev from comment #20) I've been looking at Henri's driver for some time. Unfortunately, there are DMA errors when trying to read larger amounts of data from the SD card. I've been adding debug output to the driver but haven't yet been able to pinpoint the cause of the errors. The DMA errors result in the Controller Timeouts you've seen because no interrupt is being raised. As a result e.g. CMD7 fails. This is a very important command which is part of the card intialization process. The SD card protocols are rather complex which makes understanding what is going on kind of difficult. Since FreeBSD policy dictates that new drivers have to land in HEAD first, it will probably be some time before the driver appears in older versions. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
