Not tried this myself, but does the DTS at: https://github.com/wens/linux/commit/b3df2aa9dfb48d58ee590c9686dfc0e3946de5fc help at all? Atleast to upload the firmware. I'm not sure mainline AP6210 driver for BT works because there is a problem setting up the clock on the chip. I recently added a few links about AP6210 on the linux-sunxi Bluetooth wiki page if that helps: http://linux-sunxi.org/Bluetooth Hope that helps a bit, Al -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
