First, please disregard everything I said about `CONFIG_SERIAL_DEV_BUG` -- = got another Baytrail device mixed up with this one, my bad. That said, the actu= al problem, according to my notes, is the UART's `baud_base` (2764800), result= ing in framing errors with common baud rates (i.e. 3000000 and 3500000). The sp= eed the controller is pre-set to is 3768000. I've dug the tablet up and with semi-recent musl-based Void rootfs and kernel 6.18.35 (CONFIG_SERIAL_DEV_BU= S=3Dm, btw) got `btattach -B /dev/ttyS1 -P ath3k` working by manually setting the speed with a `TCSETS2` ioctl. I=E2=80=99ve managed to pair and test some BT peripherals. @Paul, since, ultimately, this isn=E2=80=99t a kernel bug (though a patch f= or rfkill-gpio is still required), should this discussion be continued on GitH= ub? --=20 You may reply to this email to add a comment.
